How to Block XBox LIVE on a Netgear Routerby John JohnstonUpdated September 22, 2017
Connecting Xbox LIVE to your Netgear router allows you to play games and communicate with other users online. However, if you wish to have the router connected to your Xbox 360 and block your console from accessing Xbox LIVE, you can do this by blocking the ports from your router. To do this you will need to access your router and enter the specific ports that Xbox LIVE uses.
Open an Internet browser on your computer.
Enter "192.168.0.1" in your address bar and press "Enter." This will load your Netgear settings.
Click on "Services" on the left side of the screen under "Content Filtering." Give the port a name such as "Xbox LIVE." Select the type as "UDP/TCP." Select both the "Start Port" and "Finish port" as "3074." Click on the "Apply" button. Repeat this process again using port number 53. Call the second service "Xbox LIVE 1" or something similar.
Open "Services" again but this time create a port using the port type as only "UDP." Give it the name "Xbox LIVE 2." Select the start and finish ports as "88." Repeat this process once more for "Xbox LIVE 4," but select the port type as "TCP" and the start and finish port as "80." By the end of this you will have four ports opened for Xbox LIVE called Xbox LIVE, Xbox LIVE 1, Xbox LIVE 2 and Xbox LIVE 3.
Click on "Firewall Rules" on the left side of the screen under "Content Filtering." Click on the "Add" button under "Inbound Settings."
Click on the "Service Type" menu and select "Xbox LIVE." Select the action as "Block Always."
Turn on your Xbox 360 and select "System Settings." Select "Network." Make a note of the IP address for your Xbox 360. Enter this address in the "Send to LAN Server" bar. Click on the "Apply" button. Repeat this process with service types Xbox LIVE 1, Xbox LIVE 2 and Xbox LIVE 3.
