A port forwarding add-on to bypass CGNAT

One of the most common scenarios where you’ll need your router’s IP address is while setting up port forwarding to grant access to a remote device or server to a specific device on your internal network. 

However, opening a port for port forwarding can be challenging, especially if your ISP is performing CGNAT to save bandwidth and share IP addresses among multiple users on the same network.

Want to avoid the hassle and protect your IP address? Try PureVPN’s port forwarding to turn the port forwarding process into a piece of cake! Here’s how it works:

1. Log into PureVPN’s member area.
2. Navigate to the Subscription tab.
3. Select Configure.
4. Apply the required port settings.
5. Click Apply.

Protect your IP address from getting blacklisted

Setting up port forwarding is exceptionally challenging on its own, thanks to the ISP/firewall blocked ports and the difficult-to-use interface on some routers. Add CGNAT to that mix, and port forwarding becomes almost impossible for some users. But don’t worry; PureVPN has a solution for all of this!

With PureVPN’s port forwarding add-on, you can easily allow, block, and open new ports in just a few simple steps. You can also prevent your IP address from getting blacklisted for trying to bypass CGNAT by hiding your IP address with PureVPN.
