List of Ports for Special Applications

Note: Opening ports on a router can cause potential security risks. In particular, opening Terminal Services UPnP Port 3389 on Windows XP can allow Internet hackers to take over your computer if Windows XP is not patched with Microsoft's latest security updates.

Some applications require open service ports, such as Internet games, video conferencing, Internet telephony, and others. These applications cannot work with a pure NAT Router since all the ports are blocked by default. This is a result of the Router's NAT firewall function. Special Applications will allow some of these applications to work with a Router.

Trigger: This is the outbound port number that the application assigned first.
Incoming Ports: When the trigger packet is detected, the inbound packets to the specified port number are allowed to pass through the firewall.
Enable: This must be selected in order for a special application port to be activated.

This product provides some predefined settings in the drop-down menu on the bottom of the Web Page Interface. In the Popular applications drop-down menu, select an ID, and click Copy to copy a predefined setting.

Note: Only one computer can use a specific port number at a time.

The Web-based configuration utility can be used to change the settings of the Router. A brief description of these settings is provided below.

Start up and Login

Open an Internet browser and enter the Router's IP address. The following is the default IP address of the Router:

http://192.168.123.254

After the connection is established, you will see the Web User Interface for the Configuration Utility. There is no default password, so just click Login. Select Advanced (or Advanced Settings depending on your router) and then Special Applications.
