PUREVPNHow to Port Forward on Xfinity Routers and Get Around CGNAT

What is CGNAT?

Carrier-grade NAT, also known as large-scale NAT, is a type of network address translation used in IPv4 networks. In IPv4 networks that are the last remaining bastion of home computers running Windows XP and the ISPs who support them. CGNAT offers a transitional method that can extend the life of global addresses and assign a single IP address to multiple consumers on the same network.

How do I know whether I am behind CGNAT

To find out if you are on a CGNAT network, what you can do is you can visit the following websites and compare the IP address listed to the public/WAN IP address that is assigned to your internet gateway.

You can search and find your public IP address by going to the status page in the administrative interface of your Xfinity router. If the two IP addresses differ, you’re likely on an Xfinity CGNAT network.

Why is port forwarding an issue on Xfinity in Canada?

The short answer is CGNAT (Carrier-Grade NAT). Most ISPs perform CGNAT to conserve IP addresses and assign a single IP address to multiple customers, and those customers rely on the same IP address on a private network. Due to CGNAT, you can’t port forward routers even if your router is configured for port forwarding. Any port forwarding requests gets automatically rejected when your ISPs perform CGNAT.

How to forward ports and bypass CGNAT on Xfinity routers

Usually, Port Forwarding is done through your home network or Cable/DSL router when you want to get around NAT or Internet connection firewalls. However, it’s not possible with Xfinity because they apply all the NAT rules and perform CGNAT.

To allow port forwarding behind Xfinity, you’ll need PureVPN’s port forwarding add-on. With a dedicated VPN tunnel set up between your device and a VPN server, any traffic sent to this IP will bypass CGNAT rules and allow you to port forward routers.
