    Hi Guys,

    Which ports does my router have to open in order for a VPN client to access this host?

    Thanks in advance,

    For PPTP VPN connections, you need to open TCP port 1723 for PPTP tunnel maintenance traffic and permit IP Type 47 Generic Routing Encapsulation (GRE) packets for PPTP tunnel data to pass to your VPN server's IP address.

    For L2TP VPN connections, you need to open UDP port 500 for Internet Key Exchange (IKE) traffic and UDP port 1701 for L2TP traffic.
