Port forwarding for your Router

If you choose to boost the level of protection on your router, some of your favourite apps may become unavailable. In such instances, experts advise enabling port forwarding or port triggering. Thankfully, these capabilities are simple to use and can be accessed in just a few steps.

You can easily forward the information that firewall receives to a different destination. This requires that you specify the source and destination.

You may quickly configure this function on your Xfinity router by logging into your account on the Xfinity website. Go to the Connect menu after logging in with your password or ID. To get the “See Network” option, go to the menu and select “More Options.”

Then, in that menu, go to Advanced Settings and pick “Port Forwarding.” You can then add a port forward on the website. You can also use the Xfinity App to enable port forwarding. This is a similar procedure.

The port should be shut down as soon as it is no longer being used. This helps protect your network against threats.
