Forwarding
The Single Port Forwarding screen allows you to customize 
port services for various applications .
When users send these types of requests to your network 
via the Internet, the Router will forward those requests to 
the appropriate computers (also called servers) . Before using 
forwarding, you should assign static IP addresses to the 
designated computers (use the DHCP Reservation option on 
the Basic Setup screen; refer to DHCP Reservation, page 14) .
