How to open ports behind CGNAT 

What if your ISP performs CGNAT? Most ISPs perform CGNAT (Carrier-grade Network Address Translation) to conserve bandwidth and assign a single IP address to multiple users connected to the same internet network. However, CGNAT makes it difficult for you to open ports on the router. 

To get around the CGNAT issue, you can use the Port Forwarding add-on to bypass this problem and port forward routers without hassle. 

Here’s more information on how to use PureVPN’s Port Forwarding add-on and bypass CGNAT in a few clicks.

A secure way to open all ports

To most people, port forwarding is quite a demanding task. For starters, every router has a different console, which often makes it difficult to navigate to specific settings.

Secondly, you won’t always be able to open Lineage ports on your router if your ISP restricts the ports. Yes, you heard that right! ISPs are notorious for blocking ports due to security reasons. If ISP isn’t the reason behind a blocked port, then perhaps it could be your operating system’s firewall.

Well, you can eliminate all these problems and enjoy smooth online gaming on all your desired systems with PureVPN’s Port Forwarding add-on. Through the port forwarding add-on, you can allow all ports, disallow all ports, and allow specific ports.
