The data for the selected Port will then be displayed in the WAN IP Account section. WAN IP Account • User Name – The PPTP user name (login name) assigned by your ISP. • Password – The PPTP password associated with the User Name above. This is assigned by your ISP, and used to login to the PPTP Server.
4: Advanced Configuration Overview The following advanced features are provided. • Host IP Setup • Virtual Servers • Custom Virtual Server • Special Applications • Dynamic DNS • Multi DMZ • Advanced Features • UPnP This chapter contains details of the configuration and use of each of these features. Host IP Setup This feature is used in the following situations: • You have Multi-Session PPPoE, and wish to bind each session to a particular PC on your LAN.
Figure 4-1: Host IP Setup Settings – Host IP Setup Host Network Identity This section identifies each Host (PC) • Host List – When adding a new Host, ignore this list. To edit an existing entry, select it from the list, and click the "Select" button. The data fields will then be updated with data for the selected entry. • Host name – Enter a suitable name. Generally, you should use the "Hostname" (computer name) defined on the Host itself.
Host Network Binding • Bind WAN port/Session – Select Enable if you wish to associate this PC with a particular PPPoE Session. All traffic for that PC will then use the selected PPPoE port and session. • Binding Method – Suppose your PC is bound to WAN1 port, now you are selecting “Strict Binding”. If WAN1 port is disconnected, your packets cannot go out through WAN2 port, if WAN2 port is still alive.
Virtual Servers This feature allows you to make Servers on your LAN accessible to Internet users. Normally, Internet users would not be able to access a server on your LAN because: • Your Server's IP address is only valid on your LAN, not on the Internet. • Attempts to connect to devices on your LAN are blocked by the firewall in The Load Balancer. The "Virtual Server" feature solves these problems and allows Internet users to connect to your servers, as illustrated below.
Figure 4-3: Virtual Server Settings – Virtual Server Enable Use this to Enable or Disable each Virtual server as required. Server Type Select the desired Server type. If the type of Server you wish to use is not listed, use the Custom Virtual Server screen to define your own type. LAN IP Address Enter the IP address of the PC on your LAN which is running the required Server software. Each PC should have a fixed IP address, or have a reserved IP address.
Custom Virtual Servers This screen allows you to define your own Server types, for situations when the desired Server type is not listed on the Virtual Servers screen. Figure 4-4: Custom Virtual Servers Settings – Custom Virtual Servers Select Custom Server Name Server List If creating a new entry, ignore this list. To edit an existing entry, select it, and then click the "Select" button. The screen will update with data for the selected entry.
Buttons Custom Virtual Server List • Protocol Type – Select the network protocol used by this sever type. • LAN Port Range – Enter the range of port number used for outgoing traffic from this Server. If only a single port is required, enter it in both fields. • WAN Port Range - – Enter the range of port number used for incoming traffic to this Server.
Special Applications If you use Internet applications which have non-standard connections or port numbers, you may find that they do not function correctly because they are blocked by the firewall in The Load Balancer. In this case, you can define the application as a "Special Application" in order to make it work.
Outgoing Port Range Enter the beginning and end of the range of port numbers used by the application server, for data you send. If the application uses a single port number, enter it in both fields. Incoming Protocol Select the protocol used by this application, when receiving data from the remote server or PC. Incoming Port Range Enter the beginning and end of the range of port numbers used by the application server, for data you receive.
Dynamic DNS Dynamic DNS is very useful when combined with the Virtual Server feature. It allows Internet users to connect to your Virtual Servers using a URL, rather than an IP Address. This also solves the problem of having a dynamic IP address. With a dynamic IP address, your IP address may change whenever you connect to your ISP, which makes it difficult to connect to you. You must register for the Dynamic DNS service.
Settings – Dynamic DNS Dynamic DNS Service Use this to Enable/Disable the Dynamic DNS feature, and select the required service provider. • Disable – Dynamic DNS is not used. • TZO – Select this to use the TZO service (www.tzo.com). You must configure the TZO section of this screen. • Standard Client – Select this to use the standard service (from www.dyndns.org or other provider). You must configure the Standard Client section of this screen. • 3322(in China) – This is available in China.
Multi DMZ This feature allows each WAN port IP address to be associated with one (1) computer on your LAN. All outgoing traffic from that PC will be associated with that WAN port IP address. Any traffic sent to that IP address will be forwarded to the specified PC, allowing unrestricted 2-way communication between the "DMZ PC" and other Internet users or Servers. Note: The "DMZ PC" is effectively outside the Firewall, making it more vulnerable to attacks.
Settings – Multi DMZ Use this to enable or disable the DMZ setting, as required. Enable Name Enter a name to assist you to remember this setting. This name has no effect on the operation. For Static IP Public IP address Enter the WAN port (Internet) IP address you wish to associate to a PC. This IP address must have been allocated to you by your ISP. Private IP Address (LAN) Enter the IP address of the PC you wish to associate with this WAN port IP address.
UPnP With UPNP (Universal Plug & Play) function, it can easily setup and configure an entire network, enable discovery and control of networked devices and services. Figure 4-8: UPnP Settings – UPnP UPnP Option If you Enable UPnP, then this two wan router will become one of the entire local network. You can find out there is an icon show up on network neighborhood on the window XP OS. Every time you add a new network device with port mapping, The new network device will appear on the mapping list.
NAT NAT (Network Address Translation) is the technology which allows one (1) WAN (Internet) IP address to be used by many LAN users.
Settings – NAT NAT Configuration NAT Alias • NAT Routing – You can enable or disable NAT through the check box. If you disable NAT checkbox, it will act as a bridge or Static Router. Most features will be unavailable. • TCP Timeout – Enter the desired value to use on both WAN ports. The default is 300. • UDP Timeout – Enter the desired value to use on both WAN ports. The default is 120. • TCP Window Limit – Enter the desired value to use on both WAN ports. The default is 0 (no limit).
Advanced Features This screen allows you to change some advanced settings: • Remote Access Configuration – This feature allows you to manage The Load Balancer via the Internet. You can restrict access to a specified IP address or address range. • External Filters Configuration – These settings determine whether or not The Load Balancer should respond to ICMP (ping) requests received from the WAN port.
Settings – Advanced Features Remote Access Configuration • Remote Upgrade – If enabled, you can use the supplied Windows program to remotely upgrade the Firmware. If not enabled, upgrades must be performed by a PC on the LAN. • Remote Web-based setup - – If enabled, access to the Web-based interface is available via the Internet. (See below for details.) If not enabled, access is only available to PCs on the LAN. • Port – The port number used when connecting remotely. See below for details.
Interface Binding SMTP (Simple Mail Transport Protocol) Binding Unless you are using E-mail accounts from different ISPs on each port, you can ignore these settings. Some ISPs configure their E-mail Servers so they will not accept E-mail from IP addresses not allocated by themselves. If you are using accounts from different ISPs, sending E-mail over the wrong port may result in non-acceptance of the mail. In this case, you can use these settings to correct the problem.
5: Security Management Overview • URL Filter It can block specific or browse only certain website by configure IP address, URL or Key words • Access filter You can block all Internet access or select block well-known port or block user define ports by groups. • Session Limit It can eliminate users access Internet, and send email alert to the administrator.

Appendix C Troubleshooting Overview This chapter covers some common problems that may be encountered while using The Load Balancer and some possible solutions to them. If you follow the suggested steps and The Load Balancer still does not function properly, contact your dealer for further advice. General Problems Problem 1: Can't connect to The Load Balancer to configure it. Solution 1: Check the following: • The Load Balancer is properly installed, LAN connections are OK, and it is powered ON.
Solution 2: The Load Balancer processes the data passing through it, so it is not transparent. Use the Special Applications feature to allow the use of Internet applications which do not function correctly. If this does solve the problem you can use the DMZ function. This should work with most applications, but: • It is a security risk, since the firewall is disabled for the DMZ PC. • Only one (1) PC can use this feature.
