L2TP over IPSec To allow Internet Key Exchange (IKE), open UDP 500.

What is L2TP? L2TP stands for Layer 2 Tunneling Protocol, and it doesn’t provide any encryption by itself. L2TP VPN usually uses an authentication protocol, IPSec (Internet Protocol Security), for strong encryption and authentication, which gives it an ultimate edge on some other most used protocols like PPTP. The L2TP protocol uses UDP ports Which ports do you need to open on a firewall to allow To enable VPN tunnels between individual host computers or entire networks that have a firewall between them, you must open the following ports: PPTP.
