Important information for successful configuration

When you click on Add New: a new dialogue box appears with the following entries to be filled.

The Service port number: this slot is reserved for the External service port numbers. You are free to provide a single port number or a list of port numbers.

Internal port number: here, you will have to specify the internal port number as configured in the computer running the application. It can be left empty if the internal port number is similar to the external port number.

The internal IP address: this is the IP address assigned to the appliance running the service. Usually part of the LAN IP addresses.

Communication protocol: some applications will use UDP protocol for communication while others will rely on TCP for communication. You are free to specify the protocol being used. Nonetheless, you can list both protocols as active.  

Port forwarding status: the status can either be enabled or disabled. When enabled, the virtual server entry will be operational. Likewise, when the virtual server entry is disabled, the virtual server entry will be inactive. Thus, this is an indicator of the operation status of the entry, whether active or inactive.

Lastly, you will come across the Common Service Port list. The list of the Common Service Port numbers is basically a suggestion of the commonly used port numbers. However, if the port number you intended to use is not available on this list, you are free to add your own.

After filling all the required information, just go ahead and save the settings. When you go back one step, you will be able to view the list of all virtual server entries made on the router.
