Port forwarding is a technique that allows external devices to access computers or services on a private network. This is often done when you connect to a game server, use specific VoIP applications, or access a computer behind a firewall.
However, you can’t port forward on AGL networks because it’s behind CGNAT. This guide explains how you can open ports behind AGL networks without hassle.
Most ISPs perform CGNAT(Carrier-Grade Network Address Translation) to conserve their usable IPv4 pool. CGNAT is a type of NAT technology that adds another layer of address translation and assigns a single public IP address to multiple users.
The world is transitioning toward a more advanced protocol, IPv6 but the process is relatively slow. ISPs still have to acquire more IPv4 addresses to meet the demands and the depleting pool of these addresses makes the entire thing quite costly. But by performing CGNAT, ISPs do not need IPv4 addresses at hefty costs and can allocate the same IPv4 address to multiple customers simultaneously.
ISPs assign a single IP address to different users on the same network. Since all your network devices share the same public address, you can’t open ports and have to configure each device individually. This is why AGL doesn’t allow you to change port forwarding rules and performs CGNAT.
You can use the PureVPN port forwarding add-on to make this process easier. This add-on will bypass CGNAT and allow you to set up port forwarding for your devices.
Here’s how:
Opening a port shouldn’t be complicated. With the Port Forwarding add-on, it’s as simple as 1, 2, and 3!
You need a dedicated IP with a Port Forwarding add-on if you wish to host a game server, get your IP whitelisted, or want your friends to connect to your at-home devices. A Dedicated IP allows you to create servers and allow external IP addresses to connect to your server without any IP mapping issues.
