Port Forwarding Closing

Sebw31 Thank you for reaching out via our Xfinty Community Forums. We understand how frustrating it is when a port forward randomly closes. This is a known hiccup with the Xfinity Gateway that often relates to how your device's IP address is managed.

Here’s the fastest fix to try right now:

1. Delete the Old Rule: Go to the Port Forwarding section in the Xfinity app and delete the closed rule.

2. Power Cycle: Unplug your Xfinity Gateway for 60 seconds, then plug it back in. This forces it to sync with the latest settings.

3. Re-add the Rule: Use the app to re-add the port forward to your device.

Pro Tip: Check that the device you're forwarding to is set to DHCP (Automatic IP), not a static IP, in your computer's network settings.
