Port Forward on BT Broadband and bypass CGNAT gateways

If you use BT broadband, you might have faced issues with port forwarding. Customers struggle to open up ports because BT broadband performs CGNAT to conserve the IPv4 pool. Port Forwarding, however, is essential as it helps to set up communication with external servers. 

But, if a router sits behind CGNAT, you won’t be able to connect to any such external device. This guide will walk you through the step-by-step process to forward ports on BT broadband and bypass CGNAT

What is CGNAT?

CGNAT (Carrier-Grade NAT) or large-scale NAT is an address translation mechanism that tackles the issue of IPv4 exhaustion by reducing the number of allocated IP addresses. With CGNAT, multiple private IPs are translated into a single shared public address. However, a shared IP address can complicate things when you try to forward ports on BT Broadband or any router for that matter. 

Why does BT Broadband perform CGNAT?

CGNAT is mainly employed to reduce the cost spent for attaining more usable IPv4 addresses. With fewer IP addresses remaining, it is difficult for internet service providers to get new IPs for customers. By performing CGNAT, ISPs can assign the same IPv4 address to multiple users on the network and reduce the number of addresses to be acquired.

But CGNAT can also create issues when you are port forwarding routers because of a shared IP address. Your IP can get blacklisted by the ISP if you are opening ports behind CGNAT. But, there’s a quick solution to this CGNAT issue.
