Port Forwarding
Port forwarding allows you to run a publicly accessible server on your home network by specifying the
mapping of TCP/UDP ports to a local computer. This enables incoming requests on specific port
numbers to reach web servers, FTP servers, mail servers, etc. so that they can be accessible from the
Internet.
To map a port, you must enter the range of port numbers that want forwarded locally and the IP
address to which traffic to those ports should be sent. If you only want a single port specification, enter
the same port number in the start and end locations for that IP address.
A table of commonly used port numbers is also displayed on the page for your convenience. These are
some of the ports used by common applications:
