Port Range Forwarding is done so that data for Internet applications can pass through the firewall of the router or gateway. An example of an application port is Port 25 which is assigned for Email or Simple Mail Transfer Protocol (SMTP).
IMPORTANT: Ensure that you have the port numbers for the Internet application you are forwarding ports for. This may be obtained from the Application’s documentation or their website.
To set up Port Range Forwarding for Linksys routers and gateways, follow these steps:
Step 1:
Access the gateway or router’s web-based setup page by opening a web browser such as Internet Explorer or Safari . On the Address bar, enter your router’s local IP address then press [Enter] . When the login prompt appears, enter your device’s user name and password .
NOTE: The default local IP address of Linksys routers is 192.168.1.1 . For detailed instructions on how to check the IP address of your router, click here .
QUICK TIP: If you have Cisco Connect installed on your computer, you may access the router’s web-based setup page by clicking Router Settings > Advanced Settings .
Step 2:
Click the Applications & Gaming tab then click on the Port Range Forwarding sub-tab.
Step 3:
Under the Application Name , type any name you want to represent the ports being forwarded. Enter the required ports to be forwarded under Start ~ End Port , then choose the appropriate Protocol and enter the IP address of your computer or gaming console under To IP address .
NOTE: In this example, we will use the required ports for Xbox Live ® (XBOX1) and ports for a computer application (COMP1):
XBOX1: Start ~ End Port: 80 to 88; Protocol: Both (TCP and UDP)
XBOX1: Start ~ End Port: 3074 to 3074; Protocol: Both (TCP and UDP)
COMP1: Start ~ End Port: 4267 to 4269; Protocol: Both (TCP and UDP)
NOTE: To add a second computer or several wireless devices for port forwarding, add an Application Name different to that assigned for the first device and use the assigned IP address of the wireless device you wish to add to the port forwarding list. If you are using an iPhone/iPod, connect first to the wireless network then determine the IP address that is assigned by the router to your device.
Step 4:
Check the Enabled box after the IP address value and click .
NOTE: After saving, you might want to check if the settings have been properly saved. To do this, click on the Port Range Forwarding sub-tab under Applications and Gaming . If the settings have not been saved, do a router firmware upgrade. This will fix issues and possible errors on the router.

You should now have set up Port Range Forwarding on your router. In case you are still not able to do this successfully, you may connect your computer straight to the modem and check if you are able to use the Application properly.
