Title: Setting up port range forwarding on Linksys wireless-N routers and gateways

Article ID: 17241


Port range forwarding is done so the 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.

ii.   Setting up port range forwarding

Things to do before you begin

      •    Consult your device's documentation or online support site to find out what ports you need to trigger for your device as they differ depending on the application being used.

      •    Take note of the IP address of your device and the computer where you need to forward the ports to.

Setting up port range forwarding

In this example, the ports for a computer application and Xbox LIVE® game console will be forwarded.

NOTE:  For instructions on how to setup an Xbox 360® behind a Linksys router using port range forwarding, click here.

Computer application and Xbox LIVE® ports:

TCP and UDP ports:  80-88, 3074-3074, 4267-4269

Step 1:
Access your router’s web-based setup page.  To know how, click here.  If you’re using a Mac computer, click here.

QUICK TIP:  If you have Linksys Connect installed on your computer, you may access the router’s web-based setup page by clicking Router Settings > Advanced Settings.

 

If you encounter problems accessing the web-based setup page of the router, you may need to do some troubleshooting steps to successfully get in.  You can find the troubleshooting steps here.

Step 2:
Click Applications & Gaming > Port Range Forwarding.

 

Step 3:
Under the Application Name column, enter “Xbox1” and “Comp1” to represent the gaming device and computer application.

NOTE:  You may enter a different name if you like.  In this example, a total of two (2) Xbox1 lines and one (1) Comp1 line are allocated.

 

Step 4:
Enter the port numbers and IP address of the computer application and Xbox LIVE® in the required fields.

NOTE:  In this step, completing each field entry starts from left to right.

      •    Xbox1 line 1 – Enter the first value which is ports 80-88.  Since these ports are both TCP and UDP, select Both as the Protocol.  Enter the Xbox LIVE®’s IP address in the To IPv4 Address field then check Enabled.

      •    Xbox1 line 2 – Enter the second value which is port 3074-3074.  Since this port is both TCP and UDP, select Both as the Protocol.  Enter the Xbox LIVE®’s IP address in the To IPv4 Address field then check Enabled.

      •    Comp1 line 3 – Enter the third value which is ports 4267-4269.  Since these ports are both TCP and UDP, select Both as the Protocol.  Enter the computer application’s IP address in the To IPv4 Address field then check Enabled.

 

QUICK TIP:  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.

NOTE:  In this example, 192.168.1.30 is used as the Xbox LIVE®’s IP address, and 192.168.1.32 as the computer application’s IP address.

Step 5:
Click Save Settings.

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.  For instructions on how to upgrade your router’s firmware to the latest version, click here.  After the upgrade, perform the port forwarding process again.

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.
