Does Port Forwarding Work on FibreTel’s Network? #
IPv4 and CGNAT #
FibreTel uses Carrier-Grade NAT (CGNAT) for IPv4 addresses, which means multiple customers share a single public IPv4 address. This setup enhances efficiency but prevents direct port forwarding for IPv4 connections, as there’s no dedicated public IP address to forward traffic to your device.
IPv6: A Direct Solution #
For customers with IPv6-enabled devices, port forwarding isn’t necessary because IPv6 provides a direct connection between your device and the internet. This eliminates the need for NAT, and your IPv6-enabled applications can communicate seamlessly without additional configuration.
What Can You Do? #
Leverage IPv6
-
- Ensure your device or application supports IPv6.
- IPv6 offers direct connectivity, so there’s no need to configure traditional port forwarding.
Why Does FibreTel Use CGNAT for IPv4? #
IPv4 addresses are a finite resource, and CGNAT allows us to serve more customers efficiently while maintaining excellent service quality. For modern use cases, IPv6 is the way forward, offering unlimited address space and eliminating the need for NAT entirely. Most internet traffic travels over IPV6 and our network is fully IPV6 enabled.
