Setting Up Port Forwarding on Your Router

In that case, experts would advise enabling port forwarding and port triggering. Thankfully, you’ll be able to access these features easily in just a few simple steps.

To put it in the simplest way possible, port forwarding is a process of opening ports and choosing devices from the network that would receive those requests.

The information the firewall receives could be easily forwarded to a new destination. This process requires you to specify the originating source and the new destination.

The easiest way to set this feature up on your Xfinity router is to go to your account on the Xfinity website. After logging in with your password and ID, you should go to the Connect menu. You’ll need to find the “See Network” option in the menu and click on the “More Options.”

Then, find the Advanced Settings in that menu and select “Port Forwarding.” The website will then allow you to add a port forward. You can also enable port forwarding via the Xfinity app. The process is almost the same.

Port triggering is pretty useful in maintaining your security online. Using this feature, you can make a rule for a port to be open for any traffic only when you start a session with that port. As soon as you stop using it, the port should shut off, which helps you protect your network from threats.
