CGNAT port forwarding

Your solution to accessing and forwarding ports behind CGNAT

Your ISP could be utilizing CGNAT to preserve IPv4 addresses, preventing you from being able to forward or even access ports on your router. As your device behind CGNAT is lacking a public IP address, it isn’t accessible over the internet.

As a result, your router could be allocated a private IP address by the ISP’s network. Before being transmitted to the internet, this IP address is turned into the CGNAT gateway’s public IP address.

In simple words, the process of forwarding ports on the CGNAT gateway may be lengthy and could necessitate additional adjustments.

Furthermore, not all ISPs enable their customers to utilize the CGNAT gateway to set up port forwarding rules, and some might even impose extra fees.
