How to forward ports behind CGNAT on the Arris DG860 router

If you’re trying to forward ports on your Arris DG860 router while behind CGNAT, you will run into problems. CGNAT (Carrier-Grade Network Address Translation) is a type of NAT that internet service providers use to conserve IPv4 addresses. The problem is that CGNAT makes it nearly impossible to forward ports because it changes the IP addresses of devices on your network.

However, the good news is that you can use the Port Forwarding add-on by PureVPN. This add-on is designed to work with CGNAT, so you can easily forward ports while behind CGNAT.

It makes port forwarding as easy as clicking a button, with no technical knowledge required.
