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.
Click Create to add a new port forwarding rule.
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.
Application: User defined application name for the current rule.
Helper: You could also select the application type you would like to apply for automatic input.
Protocol: please select protocol type
