PPP Settings The PPP Username, PPP password and the PPPoE Service Name entries are dependent on the particular requirements of the ISP. The user name can be a maximum of 256 characters and the password a maximum of 32 characters in length. For Authentication Method, choose from AUTO, PAP, CHAP, and MSCHAP.
• • • • device has only a single IP address to assign to a LAN device. NAT and firewall are disabled when this option is selected. The device becomes the default gateway and DNS server to the PC through DHCP using the LAN interface IP address. The device extends the IP subnet at the remote service provider to the LAN PC. i.e. the PC becomes a host belonging to the same IP subnet. The device bridges the IP packets between WAN and LAN ports, unless the packet is addressed to the device’s LAN IP address.
Enable WAN Service Tick the checkbox ; to enable the WAN service. Service Name: This is the WAN Service label. STEP 6: Upon completion, click Next. The following screen appears. This screen allows for the configuration of the CT-5361T LAN interface IP address, subnet mask and DHCP server.

Click Back if you wish to modify the settings. After clicking Save/Reboot, the router will save the configuration to the flash memory and reboot.
4.2.2 MAC Encapsulation Routing (MER) STEP 4: Enter the WAN IP settings as provided by your ISP. DHCP can be enabled if the Obtain an IP address automatically checkbox ; is checked. Configuring the default gateway or the DNS with static values will disable the automatic assignment from DHCP or other WAN connection. STEP 5: Click Next to display the following screen. Enable NAT If the LAN is configured with a private IP address, the user should select this checkbox ;.
Advanced Setup menu after reboot. If firewall is not necessary, this checkbox ; should be de-selected to free up system resources for better performance. Enable IGMP Multicast Tick the checkbox ; to enable IGMP multicast (proxy). IGMP (Internet Group Membership Protocol) is a protocol used by IP hosts to report their multicast group memberships to any immediately neighboring multicast routers. Enable WAN Service Tick the checkbox ; to enable the WAN service. Service Name is user-defined.
STEP 7: Click Next to proceed to the Wireless Setup screen. To enable wireless, tick the checkbox ; and click Next. If you wish to do so, you may also change the SSID (Service Set Identifier) at this point. STEP 8: Click Next to display the configuration summary. Click Save/Reboot if the settings are correct.

6.9 Port Mapping Port Mapping supports multiple ports to PVC and bridging groups. Each group will perform as an independent network. To use this feature, you must create mapping groups with appropriate LAN and WAN interfaces using the Add button. The Remove button acts to remove mapping groups and return the ungrouped interfaces to the Default group. As shown below, when you tick the Enable virtual ports on, the LAN interfaces (ENET1-4) in the default group will separate.
To create a group from the list, first enter the group name and then select from the available interfaces on the list. Automatically Add Clients With the Following DHCP Vendor IDs: Add support to automatically map LAN interfaces to PVC's using DHCP vendor ID (option 60). The local DHCP server will decline and send the requests to a remote DHCP server by mapping the appropriate LAN interface. This will be turned on when Port Mapping is enabled. There are 4 PVCs (0/33, 0/36, 0/37, 0/38).
6.10 Certificate A certificate is a public key, attached with its owner’s information (company name, server name, personal real name, contact e-mail, postal address, etc) and digital signatures. There will be one or more digital signatures attached to the certificate, indicating that these entities have verified that this certificate is valid. 6.10.1 Local CREATE CERTIFICATE REQUEST Click Create Certificate Request to generate a certificate-signing request.

It cannot be abbreviated. The two-letter ISO abbreviation for your country.
6.10.2 Trusted CA CA is an abbreviation for Certificate Authority, which is a part of the X.509 system. It is itself a certificate, attached with the owner information of this certificate authority; but its purpose is not encryption/decryption. Its purpose is to sign and issue certificates, in order to prove that these certificates are valid. Click Import Certificate to paste the certificate content of your trusted CA.
Chapter 7 Wireless The Wireless menu provides access to the wireless options discussed below. 7.1 Basic The Basic option allows you to configure basic features of the wireless LAN interface. You can enable or disable the wireless LAN interface, hide the network from active scans, set the wireless network name (also known as SSID) and restrict the channel set based on country requirements. Click Save/Apply to apply the selected wireless options. Consult the table below for descriptions of these options.
Country Wireless Guest Network A drop-down menu that permits worldwide and specific national settings.

Rename the Wireless Guest Network as you wish. NOTE: Remote wireless hosts cannot scan Guest SSIDs. 7.
Select SSID Select the wireless network name from the drop-down box. SSID stands for Service Set Identifier. All stations must be configured with the correct SSID to access the WLAN. If the SSID does not match, that user will not be granted access. Network Authentication This option specifies whether a network key is used for authentication to the wireless network. If network authentication is set to Open, then no authentication is provided. Despite this, the identity of the client is still verified.
WEP Encryption This option specifies whether data sent over the network is encrypted. The same network key is used for data encryption and network authentication. Four network keys can be defined although only one can be used at any one time. Use the Current Network Key list box to select the appropriate network key. Encryption Strength This drop-down list box will display when WEP Encryption is enabled. The key strength is proportional to the number of binary bits comprising the key.

Appendix A: Firewall STATEFUL PACKET INSPECTION Refers to an architecture, where the firewall keeps track of packets on each connection traversing all its interfaces and makes sure they are valid. This is in contrast to static packet filtering which only examines a packet based on the information in the packet header. DENIAL OF SERVICE ATTACK Is an incident in which a user or organization is deprived of the services of a resource they would normally expect to have.

Appendix D: SSH Client Unlike Microsoft Windows, Linux OS has a ssh client included. For Windows users, there is a public domain one called “putty” that can be downloaded from here: http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html To access the ssh client you must first enable SSH access for the LAN or WAN from the Management Æ Access Control Æ Services menu in the web user interface. To access the router using the Linux ssh client For LAN access, type: ssh -l root 192.168.1.
