Port Range Forwarding
This is one of the NAPT (Network Address Port Translation) features. The Port Range Forwarding
screen allows you to set up public services on your network, such as web servers, ftp servers, e-
mail servers, or other specialized Internet applications that use one or multiple port numbers
(e.g. video conference). The port numbers being used will not change while forwarding to the
local network. This allows users on the Internet to access this server by using the WAN port IP
address and the pre-defined port numbers. When users send these types of requests to your
WAN port IP address via the Internet, the NAT Router will forward those requests to the
appropriate servers on your LAN.
Application—Enter the name of the application you wish to configure.
Start—The beginning of the port range. Enter the beginning of the range of port numbers
(external ports) used by the server or Internet application. Check with the software
documentation of the Internet application for more information if necessary.
End—The end of the port range. Enter the end of the range of port numbers (external ports)
used by the server or Internet application. Check with the software documentation of the
Internet application for more information if necessary.
