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.

Frequently Asked Questions

How do I set up port forwarding for the game server?

Port forwarding is a way to allow specific traffic from the Internet to reach your game server. To do this, you’ll need to know the IP address of your game server and which port(s) it is using for game traffic.

First, you’ll need to log into your router’s web interface. This is usually done by entering the router’s IP address into your web browser’s address bar. Once you’re logged in, look for a section called “Port Forwarding” or “NAT”.

In the port forwarding section, you’ll need to add a new rule. For the protocol, select TCP. But, for the port range, enter the port(s) that your game server is using. For the target IP, enter the IP address of your game server. Save your changes and you should be all set!

Does port forwarding improve gameplay?

Yes, port forwarding can improve gameplay by allowing your computer to connect to game servers more quickly and easily. When you port forward, you are opening up specific ports on your router that will allow traffic from the outside world to come directly to your computer. 

Port forwarding can be useful for online gaming, as it can reduce lag and make it easier for you to connect to game servers. However, it is important to note that port forwarding can also make your computer more vulnerable to attacks from hackers. Therefore, it is important to be careful when setting up port forwarding and to only open up ports that you trust.
