4.4.8.2    Port Forwarding Table 
 
Because NAT can act as a "natural" Internet firewall, your router protects your 
network from being accessed by outside users, as all incoming connection attempts 
will point to your router unless you specifically create Virtual Server entries to 
forward those ports to a PC on your network. 
 
When your router needs to allow outside users to access internal servers, e.g. a web 
server, FTP server, Email server or game server, the router can act as a "virtual 
server". You can set up a local server with a specific port number for the service to 
use, e.g. web/HTTP (port 80), FTP (port 21), Telnet (port 23), SMTP (port 25), or 
POP3 (port 110). When an incoming access request is received, it will be forwarded 
to the corresponding internal server.

This function allows any incoming data addressed to a range of service port 
numbers (from the Internet/WAN Port) to be re-directed to a particular LAN 
private/internal IP address. This option gives you the ability to handle applications 
that use more than one port such as games and audio/video conferencing.
