5. Save the settings and restart the router.

6. Go to and verify that the port is open.

7. Share your external IP address and port number (IP:Port) with people who you want to allow to connect to your server.

8. Ensure that your firewall allows incoming connections on the port you opened.

9. Launch the GMod server on your PC, and your friends should now be able to join it using your external IP address and port number.
