Have you ever encountered VPN port forwarding and thought about using it? VPN Port Forwarding lets devices on the internet connect to your private network through a secure VPN connection. This can be helpful in faster torrents or remotely controlling the devices with the LAN.

How Does VPN Port Forwarding Work?
Generally, port forwarding means redirecting the incoming internet connections to the right device in the LAN. Every device has its ports through which it can be identified with the help of the services it is offering.
Advertisement Email servers use port 587, while website uses port 80. Unfortunately, even though over 65,000 available ports are available, only a thousand are standard. The rest is available for allocation.
