1. Open a browser on your computer that’s connected to your router.
2. Enter the router’s default IP address [typically 192.168.0.1] into the address bar.
3. Enter the username and password to login to your router [usually, the username is “admin,” and the password is “password” if you haven’t changed it].
4. Navigate to the port forwarding settings page by clicking “Advanced” or “Firewall.”
5. Find the “Add Service” or “Add Rule” button and click on it.
6. Enter a name for the new port forwarding rule [e.g., “HTTP” for port 80].
7. Select the protocol and port number you want to forward [TCP or UDP].
8. Enter the static IP address of the device you wish to forward the port to [if it doesn’t have one, then assign a static IP address to your device via the router’s DHCP settings].
9. Click “Apply” or “Save” to save the new port forwarding rule.
10. You may need to restart your router for the changes to take effect.

These are the general steps you’ll need to follow to set up port forwarding on your Cisco DPC3941t router.

Your solution to accessing and forwarding  ports behind GNAT

Your ISP may be using CGNAT to conserve IPv4 addresses, making it trickier for you to access or forward ports on your router. Devices behind CGNAT are not accessible from the internet because they don’t have a public IP address. 

So, your router may have a private IP address assigned from the ISP’s network. This IP address is translated to the public IP address of the CGNAT gateway before being routed to the internet.

To put it simply, the process of forwarding ports on the CGNAT gateway can be complicated and may also require additional configurations. Moreover, not all ISPs allow their customers to create port forwarding rules on the CGNAT gateway, or they may charge extra fees.
