For IPSec VPN, the following ports are to be used: Phase 1: UDP/500. Phase 2: UDP/4500. Below is a list of some common VPN protocols and the ports that they use: PPTP (Point-to-Point Tunneling Protocol) – This protocol uses port 1723 TCP. L2TP (Layer Two Tunneling Protocol) – This protocol uses port 1701 TCP, Port 500 UDP, and port 4500 UDP.
For L2TP/IPSEC VPN connections, you need to open UDP port 500 for Internet Key Exchange (IKE) traffic, UDP port 4500 (IPsec control path) and UDP port 1701 for L2TP traffic. IPsec ESP traffic also uses IP protocol 50. SSTP connections use TCP port 443 (SSTP traffic to/from the VPN server)

For the purposes of this tutorial, we will give our VPN server an address of 10.0.5.1 on the VLAN, and connect a second server over the VLAN at 10.0.5.2.
