Learn how to enable Port Forwarding on CGNAT in simple and easy steps.
What is CGNAT?
CGNAT stands for Carrier Grade Network Address Translation. Most ISPs, including Starlink, use CGNAT to conserve their IPv4 pool. The IPv4 protocol only supports 4 billion IP addresses. ISPs perform CGNAT to assign a single IP address to multiple users, saving their already depleted IP pool.
CGNAT is a solution for ISPs who want to preserve their IPv4 infrastructure while still offering IPv6 services to their consumers. Thanks to NAT, multiple users on an IPv4 network can share a single public IP address. When users connect to the internet, their private IP address is translated to a public IP address.
Why is Port Forwarding a Problem on CGNAT?
Port Forwarding is a problem on CGNAT because your ISP assigns a private IP to you using Network Address Translator (NAT), also known as Carrier-Grade Network Address Translator (CGNAT).
The problem is that ISPs enable CGNAT, and users cannot access their friends or own host machines. Accessing remote cameras, workstations, games, or any application becomes a problem.
How to Get Around CGNAT

Host Server with a Dedicated IP and Port Forwarding
CGNAT is a solution for ISPs who want to preserve their IPv4 infrastructure while offering IPV6 services to their consumers. Thanks to NAT, multiple users on an IPv4 network can share a single public IP address. When users connect to the internet, their private IP address is translated to a public IP address.
We recommend PureVPN. PureVPN’s efficient service allows you to open ports with a few simple clicks. Having problems with CGNAT? Not a problem! PureVPN’s dedicated IP and Port Forwarding add-on bundle offer a one-click solution to circumvent CGNAT.
