Figure 5-31 The Forwarding menu
There are four submenus under the Forwarding menu (shown in Figure 5-31): Virtual Servers,
Port Triggering, DMZ and UPnP. Click any of them, and you will be able to configure the
corresponding function.

5.8.1 Virtual Servers

Choose menu “ForwardingVirtual Servers”, and then you can view and add virtual servers
in the next screen (shown in Figure 5-32). Virtual servers can be used for setting up public
services on your LAN. A virtual server is defined as a service port, and all requests from
Internet to this service port will be redirected to the computer specified by the server IP. Any
PC that was used for a virtual server must have a static or reserved IP address because its IP
address may change when using the DHCP function.
