Port Forwarding Overview
Port forwarding allows you to forward incoming traffic from the outside network, to a range of
WAN ports on an IP address on the LAN. You can also enable traffic from local network to a
specified port range to be allowed to go outside of the network in medium firewall settings.
All the settings on this page are associated with a Service Profile in the Current Profile
drop-down list. If no profile has been created, the default profile is used.
To configure port forwarding, you need to know which inbound ports the application needs.
You usually can determine this information by contacting the publisher of the application or
the relevant user groups or news groups.
A typical application of port forwarding occurs when a remote computer
’s browser needs to
access a web server running on a computer in your local network. Using port forwarding, you
can tell the gateway, “When you receive incoming traffic on port 80 (the standard port number
for a web server process), forward it to the local computer at 192.168.1.123.”
The following
sequence shows the effects of the port forwarding rule you have defined:
