Applications - Port Range Forward
By activating the port range forwarding function, remote users
can access the local network via the public IP address. Users
can assign a specific external port range to a local server.
Furthermore, users can specify an internal port range
associated in a port range forwarding rule. When the device
receives an external request to access any one of the
configured external ports, it will redirect the request to the
corresponding internal server and change its destination port to
one of the internal ports specified. Therefore, if users do not
wish for destination port to be changed for a request, the
internal port range should be left empty.
Certain applications in a LAN are available only after activating
the port range forwarding, including servers and online gaming.
When an Internet request wants to access a port, the device will
dispatch it to the IP specified. Due to security reasons, users
are suggested to limit the use of port range forwarding, and
cancel it when the application is not used.
By enabling DMZ Host Function, you can set up a DMZ host at
a particular computer exposed to the Internet. In this way, some
applications, especially online games (if the traffic port numbers
of the applications are always changing), can be easily
accessed.
From the Applications menu, click on Port Range Forward. The
following page is displayed:
