I have a Snow Leopard Server behind a Cisco RVS4000 router/firewall. I have everything on the server working well except for the VPN. For what ever reason, I can connect to my VPN while in the LAN but outside of the LAN I can not connect to my VPN. I have tried turning off the firewall and opening up all the ports on the RVS4000 but still can not connect to the VPN. What am I missing and how do I get the RVS4000 to allow me to connect to the VPN running on my server from outside my LAN?
