CHAPTER9 APPLICATIONS SETTINGS
9.1 PORT RANGE FORWARD SETUP
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 AXIMCom„s Router 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, AXIMCom‟s Router 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.
