L2TP (Layer Two Tunneling Protocol) – This protocol uses port 1701 TCP, Port 500 UDP, and port 4500 UDP.
High Compatibility – TCP is the most widely used protocol on the internet. That means most networks and firewalls play nicely with it, ensuring broad compatibility. Even in very controlled networks, ports 53 (DNS), 80 (HTTP), and 443 (HTTPS) are typically left open to allow for normal internet traffic. The Cons of Using OpenVPN With TCP
