OpenVPN is a full-featured SSL VPN which implements OSI layer 2 or 3 secure network extension using the industry standard SSL/TLS protocol, supports flexible client authentication methods based on certificates, smart cards, and/or username/password credentials, and allows user or group-specific access control policies using firewall rules applied to the VPN virtual interface. 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. A VPN port is a networking port that is used within a VPN infrastructure. They are the logical ports that enable VPN traffic to pass in and out of a VPN client or server device. Our VPN service uses these ports for Firewall configuration: For OpenVPN, we allow connections via TCP or UDP protocols on ports 443 or 1194. The IPVanish software uses port 443; Both PPTP and L2TP need the PPTP & L2TP pass-through options in the firewall/router's management interface to be enabled (if applicable).
