What port needs to be open to accept incoming VPN connections?

If you’re serious about setting up a VPN on Windows 10 using the OS built-in feature, you must understand that the setup involves a certain amount of technical knowledge.

Consumer VPN clients usually require a minimum amount of configuration. You just install them on the target computer, log into your account, and connect to the server of your choice.

Unfortunately, Windows 10-configured VPNs don’t come as easily and require a bit of elbow grease to get them working. Furthermore, you can’t select a VPN server from a different location.

One of the most important pieces of knowledge you need to acquire when it comes to Windows 10 VPN configuration is the port you need to forward to accept incoming connections.

We could just give you the answer here and you’d be on your way. The answer’s 1723; that’s the default port you need to open to accept an incoming connection.

But, for the sake of making sure nothing goes wrong, we’ll give you the full rundown.
