The Firewall > Single Port Forwarding window displays the specific port and other
settings associated with each public service that uses just a single por t.
Single Port Forwarding is one of the NAPT features and allows users of the
Internet to access this server by using the WAN port address and the matched
external port number.
When users send these types of request to your WAN port IP address via the
Internet, the NAT router forwards those requests to the appropriate servers on
your LAN.
To configure single port forwarding for the router, follow these steps:
STEP1 Click Firewall > Single Port Forwarding.
STEP 2 Configure single port forwarding settings for the router:
•Application—Enter the name of the application you wish to configure.
•External Port—Port number used by the service or Internet application.
Internet users must connect using this port number. Check with the software
documentation of the Internet application for more information.
