Now that you know what a VPN is, and what it does, it’s time to figure out which port it uses. VPNs use a port because they need to communicate with their server in order to work.

This can be done through a number of ports, but the most common ones are TCP and UDP port 443 and TCP and UDP port 22. .

Most VPNs will use either TCP or UDP, but not both. For example, NordVPN uses TCP and UDP, and IKEv2 uses both TCP and UDP.

This is because TCP is more secure, but UDP can be faster.

The only time a VPN might use a different port is if the server is only accessible on a specific port. For example, PureVPN uses UDP port 9293 because that’s the only port that the company’s servers are accessible on.

So, in conclusion, most VPNs will use either TCP or UDP, but not both.
