Wireless Controller User Manual Chapter 1. Introduction D-Link Wireless Controller (DWC), DWC-1000, is a full-featured wireless LAN controller designing for small network environment. The centralized control function contains various access point management functions, such as fast -roaming, inter-subnet roaming, automatic channel and power adjustment, self -healing etc.
Wireless Controller User Manual 1.2 Typographical Conventions The following is a list of the various terms, followed by an example of how that term is represented in this document: Product Name – D-Link Wireless Controller.
Chapter 2. Configuring Your Network: It is assumed that the user has a machine for management connected to the LAN to the controller. The LAN connection may be through the wired Ethernet ports available on the controller, or once the initial setup is complete, the DWC may also be managed through its wireless interface as it is bridged with the LAN.
Wireless Controller User Manual To configure LAN Connectivity, please follow the steps below: 1. In the LAN Setup page, enter the following information for your controller: IP address: (factory default: 192.168.10.1). If you change the IP address and click Save Settings, the GUI will not respond. Open a new connection to the new IP address and log in again.
Wireless Controller User Manual Domain Name: Enter domain name WINS Server (optional): Enter the IP address for the WINS server or, if present in your network, the Windows NetBios server. Lease Time: Enter the time, in hours, for which IP addresses are leased to clients. Enable DNS Proxy: To enable the controller to act as a proxy for all DNS requests and communicate with the ISP‘s DNS servers, click the checkbox. Relay Gateway: Enter the gateway address.
Wireless Controller User Manual 2.1.1 LAN Configuration in an IPv6 Network Advanced > IPv6 > IPv6 LAN > IPv6 LAN Config In IPv6 mode, the LAN DHCP server is enabled by default (similar to IP v4 mode). The DHCPv6 server will serve IPv6 addresses from configured address pools with the IPv6 Prefix Length assigned to the LAN. IPv4 / IPv6 mode must be enabled in the Advanced > IPv6 > Routing mode to enable IPv6 configuration options. LAN Settings The default IPv6 LAN address for the router is fec0::1.
Wireless Controller User Manual Figure 2: IPv6 LAN and DHCPv6 configuration If you change the IP address and click Save Settings, the GUI will not respond. Open a new connection to the new IP address and log in again. Be sure the LAN host (the machine used to manage the router) has obtained IP address from newly assigned pool (or has a static IP address in the router‘s LAN subnet) before accessing the router via changed IP address. As with an IPv4 LAN network, the router has a DHCPv6 server.
Wireless Controller User Manual The following settings are used to configure the DHCPv6 server: DHCP Mode: The IPv6 DHCP server is either state less or stateful. If stateless is selected an external IPv6 DHCP server is not required as the IPv6 LAN hosts are auto-configured by this controller. In this case the controller advertisement daemon (RADVD) must be configured on this device and ICMPv6 controller discovery messages are used by the host for auto -configuration.
Wireless Controller User Manual 2.1.2 Configuring IPv6 Router Advertisements Router Advertisements are analogous to IPv4 DHCP assignments for LAN clients, in that the router will assign an IP address and supporting network information to devices that are configured to accept such details. Rout er Advertisement is required in an IPv6 network is required for stateless auto configuration of the IPv6 LAN.
Wireless Controller User Manual Figure 3: Configuring the Router Advertisem ent Daemon Advertisement Prefixes Advanced > IPv6 > IPv6 LAN > Advertisement Prefixes The router advertisements configured with advertisement prefixes allow this router to inform hosts how to perform stateless address auto configuration. Router advertisements contain a list of subnet prefixes that allow the router to determine neighbors and whether the host is on the same link as the router.
Wireless Controller User Manual IPv6 Prefix Length: This value indicates the number contiguous, higher order bits of the IPv6 address that define up the network portion of the address. Typically this is 64. Prefix Lifetime: This defines the duration (in seconds) that the requesting node is allowed to use the advertised prefix. It is analogous to DHCP lease time in an IPv4 network. Figure 4: IPv6 Advertisement Prefix settings 2.
Wireless Controller User Manual will allow traffic from LAN hosts belonging to this VLAN ID to pass through to other configured VLAN IDs that have Inter VLAN Routing enabled. Figure 5: Adding VLAN memberships to the LAN 2.2.1 Associating VLANs to ports In order to tag all traffic through a specific LAN port with a VLAN ID, you can associate a VLAN to a physical port. Setup > VLAN Settings > Port VLAN VLAN membership properties for the LAN and wireless LAN are listed on this page.
Wireless Controller User Manual to the switch port on the controller will be tagged. Data passing through the phone from a connected device will be untagged. Figure 6: Port VLAN list In Access mode the port is a member of a single VLAN (and only one). All data going into and out of the port is untagged. Traffic through a port in access mode looks like any other Ethernet frame. In Trunk mode the port is a member of a user selectable set of VLANs. All data going into and out of the port is tagged.
Wireless Controller User Manual Figure 7: Configuring VLAN membership for a port 2.3 Configurable Port: DMZ Setup This controller supports one of the physical ports to be configured as a secondary WAN Ethernet port or a dedicated DMZ port. A DMZ is a subnetwork that is open to the public but behind the firewall. The DMZ adds an additional layer of security to the LAN, as specific services/ports that are exposed to the internet on the DMZ do not have to be exposed on the LAN.
Wireless Controller User Manual Figure 8: DMZ configuration In order to configure a DMZ port, the controller configurable port must be set to DMZ in the Setup > Internet Settings > Configurable Port page. 2.4 Universal Plug and Play (UPnP) Advanced > Advanced Network > UPnP Universal Plug and Play (UPnP) is a feature that allows the controller to discovery devices on the network that can communicate with the controller and allow for auto configuration.
Wireless Controller User Manual Advertisement Period: This is the frequency that the controller broadcasts UPnP information over the network. A large value will minimize network traffic but cause delays in identifying new UPnP devices to the network. Advertisement Time to Live: This is expressed in hops for each UPnP packet. This is the number of steps a packet is allowed to propagate before being discarded. Small values will limit the UPnP broadcast range.
Wireless Controller User Manual 2.5 Captive Portal LAN users can gain internet access via web portal authentication with the DWC. Also referred to as Run-Time Authentication, a Captive Portal is ideal for a web café scenario where users initiate HTTP connection requests for web access but are not interested in accessing any LAN services.

Wireless Controller User Manual Figure 23: Connection Status information of Option1 The WAN status page allows you to Enable or Disable static WAN links. For WAN settings that are dynamically received from the ISP, you can Renew or Release the link parameters if required. 3.3 Features with Multiple WAN Links This controller supports multiple WAN links.
Wireless Controller User Manual Setup > Internet Settings > Option Mode To use Auto Failover or Load Balancing, WAN link failure detection must be configured. This involves accessing DNS servers on the internet or ping to an internet address (user defined). If required, you can configure the number of retry attempts when the link seems to be disconnected or the threshold of failures that determines if a WAN port is down. 3.3.
Wireless Controller User Manual and let low-volume background traffic (such as SMTP) go over the lower speed link. Protocol binding is explained in next section. Spill Over: If Spill Over method is selected, WAN1 acts as a dedicated link till a threshold is reached. After this, WAN2 will be used for new connections. You can configure spill-over mode by using folloing options: Load Tolerance: It is the percentage of bandwidth after which the controller switches to secondary WAN.
Wireless Controller User Manual Figure 24: Load Balancing is available when multiple WAN ports are configured and Protocol Bindings have been defin ed 3.3.3 Protocol Bindings Advanced > Routing > Protocol Bindings Protocol bindings are required when the Load Balancing feature is in use. Choosing from a list of configured services or any of the user -defined services, the type of traffic can be assigned to go over only one of the available WAN ports.
Wireless Controller User Manual applicable when load balancing mode is enabled and more than one WAN is configured. Figure 25: Protocol binding se tup to associate a service and/or LAN source to a WAN and/or destination network 3.4 Routing Configuration Routing between the LAN and WAN will impact the way this controller handles traffic that is received on any of its physical interfaces. The routing mo de of the gateway is core to the behaviour of the traffic flow between the secure LAN and the internet.
Wireless Controller User Manual NAT is a technique which allows several computers on a LAN to share an Internet connection. The computers on the LAN use a "private" IP address range while the WAN port on the controller is configured with a single "public" IP address. Along with connection sharing, NAT also hides internal IP addresses from the computers on the Internet. NAT is required if your ISP has assigned only one IP address to you.
Wireless Controller User Manual Figure 26: Routing Mode is used to conf igure tr affic routing between WAN and LAN, as well as Dynamic routing (RIP) 51
Wireless Controller User Manual 3.4.2 Dynamic Routing (RIP) Setup > Internet Settings > Routing Mode Dynamic routing using the Routing Information Protocol (RIP) is an Interior Gateway Protocol (IGP) that is common in LANs. With RIP this controller can exchange routing information with other supported controllers in the LAN and allow for dynamic adjustment of routing tables in order to adapt to modifications in the LAN without interrupting traffic flow.
Wireless Controller User Manual 3.4.3 Static Routing Advanced > Routing > Static Routing Advanced > IPv6 > IPv6 Static Routing Manually adding static routes to this device allows you to define the path selection of traffic from one interface to another.

Wireless Controller User Manual Chapter 5. Securing the Private Network You can secure your network by creating and applying rules that your controller uses to selectively block and allow inbound and outbound Internet traffic. You then specify how and to whom the rules apply.
Wireless Controller User Manual may use the IP address if a static address is ass igned to the WAN port, or if your WAN address is dynamic a DDNS (Dynamic DNS) name can be used. Outbound (LAN/DMZ to WAN) rules restrict access to traffic leaving your network, selectively allowing only specific local users to access specific outside resou rces. The default outbound rule is to allow access from the secure zone (LAN) to either the public DMZ or insecure WAN.
Wireless Controller User Manual Figure 62: List of Available Schedules to bind to a firewall rule 5.3 Configuring Firewall Rules Advanced > Firewall Settings > Firewall Rules All configured firewall rules on the controller are displayed in the Firewall Rules list. This list also indicates whether the rule is enabled (active) or not, and gives a summary of the From/To zone as well as the services or users that the rule affects. To create a new firewall rules, follow the steps be low: 1.
Wireless Controller User Manual Service: ANY means all traffic is affected by this rule. For a specific service the drop down list has common services, or you can select a custom defined service. Action & Schedule: Select one of the 4 actions that this rule defines: BLOCK always, ALLOW always, BLOCK by schedule otherwise ALLOW, or ALLOW by schedule otherwise BLOCK. A schedule must be preconfigured in order for it to be available in the dropdown list to assign to this rule.
Wireless Controller User Manual External IP address: The rule can be bound to a specific WAN interface by selecting either the primary WAN or configurable port WAN as the source IP address for incoming traffic. This controller supports multi-NAT and so the External IP address does not necessarily have to be the WAN address. On a single WAN interface, multiple public IP addresses are supported.
Wireless Controller User Manual Figure 63: Example where an outbound SNAT rule is used to map an external IP address (209.156.200.225) to a private DMZ IP address (10.30 .30.
Wireless Controller User Manual Figure 64: The firewall rule configuration page allows you to define the To/From zone, service, action, schedules, and specify source/destination IP addresses as needed. 5.3.1 Firewall Rule Configuration Examples Example 1: Allow inbound HTTP traffic to the DMZ Situation: You host a public web server on your local DMZ network. You want to allow inbound HTTP requests from any outside IP address to the IP address of your web server at any time of day.
Wireless Controller User Manual Service HTTP Action ALLOW always Send to Local Server (DNAT IP) 192.168.5.2 (web server IP address) Destination Users Any Log Never Example 2: Allow videoconferencing from range of outside IP addresses Situation: You want to allow incoming videoconferencing to be initiated from a restricted range of outside IP addresses (132.177.88.2 - 132.177.88.254), from a branch office. Solution: Create an inbound rule as follows.
Wireless Controller User Manual Web server host in the DMZ, IP address: 192.168.12.222 Access to Web server: (simulated) public IP address 10.1.0.52 Parameter E Value x Zone From Insecure (WAN1/WAN2) a TomZone p Service l Action e Public (DMZ) HTTP ALLOW always Send to Local Server (DNAT IP) 4 Destination Users : From 192.168.12.222 ( web server local IP address) Single Address 10.1.0.
Wireless Controller User Manual Figure 65: Schedule configuration for the above example. 2. Since we are trying to block HTTP requests, it is a service with To Zone: Insecure (WAN1/WAN2) that is to be blocked according to schedule ―Weekend‖. 3. Select the Action to ―Block by Schedule, otherwise allow‖. This will take a predefined schedule and make sure the rule is a blocking rule during the defined dates/times. All other times outside the schedule will not be affected by this firewall blocking rule 4.
Wireless Controller User Manual 8. The last step is to enable this firewall rule. Select the rule, and click ―enable‖ below the list to make sure the firewall rule is active 5.4 Security on Custom Services Advanced > Firewall Settings > Custom Services Custom services can be defined to add to the list of services available during firewall rule configuration. While common services have known TCP/UDP/ICMP ports for traffic, many custom or uncommon applications exist in the LAN or WAN.
Wireless Controller User Manual Figure 67: Available ALG support on the controller. 5.6 VPN Passthrough for Firewall Advanced > Firewall Settings > VPN Passthrough This controller‘s firewall settings can be configured to allow encrypted VPN traffic for IPsec, PPTP, and L2TP VPN tunnel connections between the LAN and internet. A specific firewall rule or service is not appropriate to introduce this passthrough support; instead the appropriate check boxes in the VPN Passthrough page must be enabled.
Wireless Controller User Manual Figure 68: Passthrough options for VPN tunnels 5.7 Application Rules Advanced > Application Rules > Application Rules Application rules are also referred to as port triggering. This feature allows devices on the LAN or DMZ to request one or more ports to be forwarded to them. Port triggering waits for an outbound request from the LAN/DMZ on one of the defined outgoing ports, and then opens an incoming port for that specified type of traffic.
Wireless Controller User Manual ports. The controller has a list of common applications and games with corresponding outbound and inbound ports to open. You can also specify a port triggering rule by defining the type of traffic (TCP or UDP) and the range of incoming and outgoing ports to open when enabled. Figure 69: List of Available Application Rul es showing 4 unique rules The application rule status page will list any active rules, i.e.

Domains added to this list are allowed in any form. For example, if the domain ―yahoo‖ is added to this list then all of the following URL‘s are permitted access from the LAN: www.yahoo.com , yahoo.co.uk, etc.
Wireless Controller User Manual Figure 71: Two trusted domains added to the Approved URLs List 5.8.3 Blocked Keywords Advanced > Website Filter > Blocked Keywords Keyword blocking allows you to block all website URL‘s or site content that contains the keywords in the configured list. This is lower priority than the Approved URL List; i.e. if the blocked keyword is present in a site allowed by a Trusted Domain in the Approved URL List, then access to that site will be allowed.
Wireless Controller User Manual Figure 72: One keyword added to the block list 5.8.4 Export Web Filter Advanced > Website Filter > Export Export Approved URLs: Feature enables the user to export the URLs to be allowed to a csv file which can then be downloaded to the local host. The user has to click the export button to get the csv file. Export Blocked Keywords: This feature enables the user to export the keywords to be blocked to a csv file which can then be downloaded to the local host.
Wireless Controller User Manual Figure 73: Export Approved URL list 5.9 IP/MAC Binding Advanced > IP/MAC Binding Another available security measure is to only allow outbound traffic (from the LAN to WAN) when the LAN node has an IP address matching the MAC address bound to it. This is IP/MAC Binding, and by enforcing the gateway to validate the source traffic‘s IP address with the unique MAC Address of the configured LAN node, the administrator can ensure traffic from that IP address is not spoofed.
Wireless Controller User Manual Figure 74: The following example binds a LAN host’s MAC Address to an IP address served by DWC-1000. If there is an IP/MAC Binding violation, the violating packet will be dropped and logs will be captured 5.10 Protecting from Internet Attacks Advanced > Advanced Network > Attack Checks Attacks can be malicious security breaches or unintentional network issues that render the controller unusable.

Wireless Controller User Manual Chapter 6. IPsec / PPTP / L2TP VPN A VPN provides a secure communication channel (―tunnel‖) between two gateway controller or a remote PC client. The following types of tunnels can be created: Gateway-to-gateway VPN: to connect two or more controller to secure traffic between remote sites. Remote Client (client-to-gateway VPN tunnel): A remote client initiates a VPN tunnel as the IP address of the remote PC client is not known in advance.
Wireless Controller User Manual Figure 77: Example of three IPsec client connections to the internal network through the DWC IPsec gateway 118
Wireless Controller User Manual 6.1 VPN Wizard Setup > Wizard > VPN Wizard You can use the VPN wizard to quickly create both IKE and VPN policies. Onc e the IKE or VPN policy is created, you can modify it as required. Figure 78: VPN Wizard launch screen To easily establish a VPN tunnel using VPN Wizard, follow the steps below: 1. Select the VPN tunnel type to create The tunnel can either be a gateway to gateway connection (site -to-site) or a tunnel to a host on the internet (remote access).
Wireless Controller User Manual 2. Configure Remote and Local WAN address for the tunnel endpoints Remote Gateway Type: identify the remote endpoint of the tunnel by FQDN or static IP address Remote WAN IP address / FQDN: This field is enabled only if the peer you are trying to connect to is a Gateway. For VPN Clients, this IP address or Internet Name is determined when a connection request is received from a client.
Wireless Controller User Manual Parameter Default value from Wizard Exchange Mode Aggressive (Client policy ) or Main (Gateway policy) ID Type FQDN Local WAN ID wan_local.com (only applies to Client policies) Remote WAN ID wan_remote.
Wireless Controller User Manual Figure 79: IPsec policy configuration Once the tunnel type and endpoints of the tunnel are defined you can determine the Phase 1 / Phase 2 negotiation to use for the tunnel. This is covered in the IPsec mode setting, as the policy can be Manual or Auto. For Auto policies, the Internet Key Exchange (IKE) protocol dynamically exchanges keys between two IPsec hosts. The Phase 1 IKE parameters are used to define the tunnel‘s security association details.
Wireless Controller User Manual Figure 80: IPsec policy configuration continued (Auto policy via IKE) A Manual policy does not use IKE and instead relies on manual keying to exchange authentication parameters between the two IPsec hosts. The incoming and outgoing security parameter index (SPI) values must be mirrored on the remote tunnel endpoint. As well the encryption and integrity algorithms and keys must match on the remote IPsec host exactly in order for the tunnel to establish successfu lly.
Wireless Controller User Manual Figure 81: IPsec policy configuration continued (Auto / Manual Phase 2) 6.2.1 Extended Authentication (XAUTH) You can also configure extended authentication (XAUTH). Rather than configure a unique VPN policy for each user, you can configure the VPN gateway controller to authenticate users from a stored list of user accou nts or with an external authentication server such as a RADIUS server.
Wireless Controller User Manual 6.3 Configuring VPN clients Remote VPN clients must be configured with the same VPN policy parameters used in the VPN tunnel that the client wishes to use: encrypti on, authentication, life time, and PFS key-group. Upon establishing these authentication parameters, the VPN Client user database must also be populated with an account to give a user access to the tunnel. VPN client software is required to establish a VP N tunnel between the controller and remote endpoint.
Wireless Controller User Manual Figure 82: PPTP tunnel configuration – PPTP Client Figure 83: PPTP VPN connection status Setup > VPN Settings > PPTP > PPTP Server A PPTP VPN can be established through this controller. Once enabled a PPTP server is available on the controller for LAN and WAN PPTP client users to access. Once the PPTP server is enabled, PPTP clients that are within the range of configured IP addresses of allowed clients can reach the controller‘s PPTP server.

Wireless Controller User Manual Figure 95: User configuration options 7.2 Using SSL VPN Policies Setup > VPN Settings > SSL VPN Server > SSL VPN Policies SSL VPN Policies can be created on a Global, Group, or User level. User level policies take precedence over Group level policies and Group level policies take precedence over Global policies. These policies can be applied to a specific network resource, IP address or ranges on the LAN, or to different SSL VPN services supported by the controller.
Wireless Controller User Manual Figure 96: List of SSL VPN polices (Global filter) To add a SSL VPN policy, you must first assign it to a user, group, or make it global (i.e. applicable to all SSL VPN users). If the policy is for a group, the available configured groups are shown in a drop down menu and one must be selected. Similarly, for a user defined policy a SSL VPN user must be chosen from the available list of configured users. The next step is to define the policy details.
Wireless Controller User Manual Figure 97: SSL VPN policy configuration To configure a policy for a single user or group of users, enter the following information: Policy for: The policy can be assigned to a group of users, a single user, or all users (making it a global policy). To customize the policy for specific users or groups, the user can select from the Available Groups and Available Users drop down.

Traffic from the remote user to the controller is detected and re-routed based on configured port forwarding rules.
Wireless Controller User Manual VNC (virtual network computing) 5900 or 5800 As a convenience for remote users, the hostname (FQDN) of the network server can be configured to allow for IP address resolution. This host name resolution provides users with easy-to-remember FQDN‘s to access TCP applications instead of error prone IP addresses when using the Port Forwarding service through the SSL User Portal.
Wireless Controller User Manual Figure 99: List of Available Applications for SSL Port Forwarding 7.4 SSL VPN Client Configuration Setup > VPN Settings > SSL VPN Client > SSL VPN Client An SSL VPN tunnel client provides a point -to-point connection between the browserside machine and this controller. When a SSL VPN client is launched from the user portal, a "network adapter" with an IP address from the corporate subnet, DNS and WINS settings is automatically created.
Wireless Controller User Manual Figure 100: SSL VPN client adapter and access configuration The controller allows full tunnel and split tunnel support. Full tunnel mode just sends all traffic from the client across the VPN tunnel to the controller. Split tunnel mode only sends traffic to the private LAN based on pre -specified client routes. These client routes give the SSL client access to spe cific private networks, thereby allowing access control over specific LAN services.
Wireless Controller User Manual Setup > VPN Settings > SSL VPN Client > Configured Client Routes If the SSL VPN client is assigned an IP addr ess in a different subnet than the corporate network, a client route must be added to allow access to the private LAN through the VPN tunnel. As well a static route on the private LAN‘s firewall (typically this controller) is needed to forward private traffic through the VPN Firewall to the remote SSL VPN client.
Wireless Controller User Manual The controller administrator creates and edits portal layouts from the configuration pages in the SSL VPN menu. The portal name, title, banner name, and banner contents are all customizable to the intended user s for this portal. The portal name is appended to the SSL VPN portal URL.

Wireless Controller User Manual Chapter 8. Advanced Configuration Tools 8.1 USB Device Setup Setup > USB Settings > USB Status The DWC-1000 Wireless controller has a USB interface for printer access, file sharing. There is no configuration on the GUI to enable USB device support. Upon inserting your USB storage device, printer cable the DWCwill automatically detect the type of connected peripheral.
Wireless Controller User Manual Figure 103: USB Device Detection 8.2 Authentication Certificates Advanced > Certificates This gateway uses digital certificates for IPsec VPN authentication as well as SSL validation (for HTTPS and SSL VPN authentication). You can obtain a digital certificate from a well-known Certificate Authority (CA) such as VeriSign, or generate and sign your own certificate using functionality available on this gateway.
Wireless Controller User Manual A self certificate is a certificate issued by a CA identifying your de vice (or selfsigned if you don‘t want the identity protection of a CA). The Active Self Certificate table lists the self certificates currently loaded on the gateway. The following information is displayed for each uploaded self certificate: Name: The name you use to identify this certificate, it is not displayed to IPsec VPN peers or SSL users.
Wireless Controller User Manual Figure 104: Certificate summary for IPsec and HTTPS management 8.3 WIDS Security 8.3.1 WIDS AP configration Advanced > WIDS Security > AP The WIDS AP Configuration page allows you to activate or deactivate various threat detection tests and set threat detection thresholds in order to help detect rogue APs on the wireless network. These changes can be done without disrupting network connectivity.
Wireless Controller User Manual Managed SSID from an unknown AP: This test checks whether an unknown AP is using the managed network SSID. A hacker may set up an AP with managed SSID to fool users into associating with the AP and revealing password and other secure information. Administrators with large networks who are using multiple clusters should either use different network names in each cluster or disable this test.
Wireless Controller User Manual AP is operating on an illegal channel: The purpose of this test is to detect hackers or incorrectly configured devices that are operating on channels that are not legal in the country where the wireless system is set up. Note: In order for the wireless system to detect this threat, the wireless network must contain one or more radios that operate in sentry mode.
Wireless Controller User Manual AP De-Authentication Attack: Enable or disable the AP de-authentication attack. The wireless controller can protect against rogue APs by sending DE authentication Messages to the rogue AP. The de-authentication attack feature must be globally enabled in order for the wireless system to do this function. Make sure that no legitimate APs are classified as rogues before enabling the attack feature. This feature is disabled by default. Figure 105: WIDS AP Configuration 8.3.
Wireless Controller User Manual In order to help determine whether a client is posing a threat to the network by flooding the network with management traffic, the system keeps track of the number of times the AP received each message type and the highest message rate detected in a single RF Scan report. On the WIDS Client Configuration page, you can set thresholds for each type of message sent, and the APs monitor whether any clients exceed those thresholds or tests.
Wireless Controller User Manual Rogue Detected Trap Interval: Specify the interval, in seconds, between transmissions of the SNMP trap telling the administrator that rogue APs are present in the RF Scan database. If you set the value to 0, the trap is never sent. De-Authentication Requests Threshold Interval : Specify the number of seconds an AP should spend counting the DE authentication messages sent by wireless clients.
Wireless Controller User Manual Figure 106: WIDS Client Configuration 160
Wireless Controller User Manual Chapter 9. Administration & Management 9.1 Remote Management Both HTTPS and telnet access can be restricted to a subset of IP addresses. The controller administrator can define a known PC, single IP address or range of IP addresses that are allowed to access the GUI with HTTPS. The opened port for SSL traffic can be changed from the default of 443 at the same time as defining the allowed remote management IP address range. Figure 107: Remote Management 9.
Wireless Controller User Manual 9.3 SNMP Configuration Tools > Admin > SNMP SNMP is an additional management tool that is useful when multiple controller in a network are being managed by a central Master system. When an external SNMP manager is provided with this controller Management Information Base (MIB) file, the manager can update the controller hierarchal variables to view or update configuration parameters.
Wireless Controller User Manual Figure 109: SNMP system information f or this controller 9.4 Configuring Time Zone and NTP Tools > Date and Time You can configure your time zone, whether or not to adjust for Daylight Savings Time, and with which Network Time Protocol (NTP) server to synchronize the date and time. You can choose to set Date and Time manually, which will store the information on the controller real time clock (RTC).
Wireless Controller User Manual Figure 110: Date, Time, and NTP server setup 9.5 Log Configuration This controller allows you to capture log messages for traffic through the firewall, VPN, and over the wireless AP. As an administrator you can monitor the type of traffic that goes through the controller and also be notified of potential attacks or errors when they are detected by the controller. The following sections describe the log configuration settings and the ways you can access these logs.
Wireless Controller User Manual 9.5.1 Defining What to Log Tools > Log Settings > Logs Facility The Logs Facility page allows you to determine the granularity of logs to receive from the controller. There are three core components of the controller, referred to as Facilities: Kernel: This refers to the Linux kernel. Log messages that correspond to this facility would correspond to traffic through the firewall or network stack.
Wireless Controller User Manual Figure 111: Facility settings for Logging The display for logging can be customized based on where the logs are sent, either the Event Log viewer in the GUI (the Event Log viewer is in the Status > Logs page) or a remote Syslog server for later review. E -mail logs, discussed in a subsequent section, follow the same configuration as logs configured for a Syslog server.
Wireless Controller User Manual Example: If Accept Packets from LAN to WAN is enabled and there is a firewall rule to allow SSH traffic from LAN, then whenever a LAN machine tries to make an SSH connection, those packets will be accepted and a message will be logged. (Assuming the log option is set to Allow for the SSH firewall rule.) Dropped Packets are packets that were intentionally blocked from being transferred through the corresponding network segment.
Wireless Controller User Manual Figure 112: Log configuration options for traffic through controller 9.5.2 Sending Logs to E-mail or Syslog Tools > Log Settings > Remote Logging Once you have configured the type of logs that you want the controller to collect, they can be sent to either a Syslog server or an E -Mail address. For remote logging a key configuration field is the Remote Log Identifier.
Wireless Controller User Manual send a valid e-mail that is accepted by one of the configured ―send -to‖ addresses. Up to three e-mail addresses can be configured as log recipients. In order to establish a connection with the configured SMTP port and server, define the server‘s authentication requirements. The controller supports Login Plain (no encryption) or CRAM-MD5 (encrypted) for the username and password data to be sent to the SMTP server.
Wireless Controller User Manual Figure 113: E-mail configuration as a Remote Logging option An external Syslog server is often used by network administrator to collect and store logs from the controller. This remote device typically has less memory constraints than the local Event Viewer on the controller GUI, and thus can collect a considerable number of logs over a sustained period. This is ty pically very useful for debugging network issues or to monitor controller traffic over a long duration.
Wireless Controller User Manual Figure 114: Syslog server configuration for Remote Logging ( continued) 9.5.3 Event Log Viewer in GUI Status > Logs > View All Logs The controller GUI lets you observe configured log messages from t he Status menu. Whenever traffic through or to the controller matches the settings determined in the Tools > Log Settings > Logs Facility or Tools > Log Settings > Logs Configuration pages, the corresponding log message will be displayed in this window with a timestamp.
Wireless Controller User Manual Figure 115: VPN logs displayed in GUI event viewer 9.6 Backing up and Restoring Configuration Settings Tools > System You can back up the controller custom configuration settings to restore them to a different device or the same controller after some other changes. During backup, your settings are saved as a file on your host. You can restore the controller saved settings from this file as well.
Wireless Controller User Manual 9. To restore your saved settings from a backup file, click Browse then locate the file on the host. After clicking Restore, the controller begins importing the file‘s saved configuration settings. After the restore, the controller reboots automatically with the restored settings. 10. To erase your current settings and revert to factory default settings, click the Default button.
Wireless Controller User Manual IMPORTANT! During firmware upgrade, do NOT try to go online , turn off the DWC-1000, shut down the PC, or interrupt the process in anyway until the operation is complete. This should take only a minute or so including the reboot process. Interrupting the upgrade process at specific points when the flash is being written to may corrupt the flash memory and render the controller unusable without a low-level process of restoring the flash firmware (not through the web GUI).
