  3. Navigate to the port forwarding section of your router.
  4. Click on Port Forwarding.

PureVPN’s Port Forwarding Add-on

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 Apache Tomcat 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 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.
