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.
