How to Start VPN from Terminal – Internet Connection

Hello All, I'm trying to figure out how to start a VPN connection form a tunnel built in Internet Connection. I have a working config, I have shell access, and when the tunnel is up, I have ARD access. This host is behind a linksys in a remote office. The XServe is in a datacenter. I've tried to use Automater, Apple Script and scoured posts and the command line options. If I understand correctly, vpnd is for a VPN server, yes? The XServe is the VPN server in my case. I want a client session to be initiated from a working config. This is all Tiger based, latest updates. Thanks in Advance, Eddy
