- Open the Comcast Network settings page and select the Network option.
- Click Advanced Settings followed by LAN & WAN, and edit the DHCP range to cover the Static IP address of your device.
- Make sure that you configured the correct ports and check whether the IP address of the server is listed on the Router setup page.
- If the static IP is not in the required range, the port forwarding will not take place.
- Click the Back button and select Port Forwarding to add the correct ports to solve Comcast router port forwarding not working.
- Now, reset the DHCP range to the default values. Check whether the port responds to the Internet.
- Also, check if you can access the server from another computer that is on the same network to verify the Internet connection.
- If the connection fails, check if the default gateway is configured in the server correctly.
- If the Comcast router port forwarding not working problem persists, check the firewall settings in the router and ensure that it is allowing the incoming server.
