VPN ports are virtual network ports that VPN protocols use to handle secure connections between a client and a VPN server. Through these ports, traffic travels securely through an encrypted tunnel. Default VPN ports depend on a VPN protocol. However, a user can customize them. The most common VPN ports include 1194 for OpenVPN UDP and TCP port 443, 500 for IPsec/IKEv2, and 1723 for PPTP.
