  Figure 4-53 The Forwarding menu 
There are four submenus under the Forwarding menu (shown in Figure 4-53): Virtual Servers, 
Port  Triggering,  DMZ  and  UPnP.  Click  any  of  them,  and  you  will  be  able  to  configure  the 
corresponding function. 
4.11.1  Virtual Servers 
Choose menu “Forwarding→Virtual Servers”, and then you can view and add virtual servers in 
the next screen (shown in Figure 4-54). 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.
