Port Forwarding Page
Path:
Advanced > Port Forwarding
Port forwarding is a method of making a computer on your network accessible to computers on the
Internet, even though you are behind the Gateway. The Port Forwarding page lets you configure
port-forwarding services that allow Internet users access to predefined services such as HTTP (80),
FTP (20/21), and AIM/ICQ (5190) as well as custom-defined (other) services. You perform port
forwarding by redirecting the WAN IP address and the service port to a local IP address and service
port.
Every program on your computer that uses the internet is programmed to send its packets through
specific ports. Ports are virtual pathways over which information on the Internet travels. A good analogy
is to think of ports like extensions on a phone system. Sometimes the ports are selected arbitrarily by
the programmers of the software, but other times programmers use a standard port, depending on the
functionality of the software. Examples of industry-standard uses for common ports are:
HTML pages: port 80
FTP file transferring: port 21
POP3 email: port 110
MSN Messenger: port 6901 and ports 6891-6900
