You can use the Virtual Server to forward an individual port to one of your computers. You cannot forward the same port to multiple computers. In order to configure the Virtual Server you need to know the IP address of the computer that needs the port opened and the service port number. The links below will help you find the IP address of your machine. If you don’t know which port needs to be opened, try checking the software manufacture’s support website for information on use behind firewall.
Configuring the Virtual Server:
Step 1: Access the device configuration by entering 192.168.0.1 in your web browser. Login with your username and password. The default username is admin and the password is blank.
Step 2a: If the port you need to forward is a common port, it will be under the predefined virtual server list at the bottom of the page. Click the pad and paper icon next to the virtual server entry you want to use. The Protocol Type and Service Port fields are preconfigured. Click the Enable radio button to use the virtual server. Enter the private IP address of the computer that will use the service port. Configure the Schedule as needed, then Apply your settings.
Step 2b: If the port you need to forward is not listed under the predefined virtual server list at the bottom of the page, you can create a new entry for your application. Click the Enable radio button to use the virtual server. Give your virtual server a name. Next, enter the private IP address of the computer that will use the service port. Then, select the Protocol Type and enter the Service Port. If you don’t know how to use Private and Public port assignment, then just enter the same port number in both fields. Configure the Schedule as needed and Apply your settings.
