You mean outbound right?  And there really isn't such a thing as "vpn"; 
there is: PPTP, IPSec, VTUN, L2TP, OpenVPN, etc... all of which have
quite different connection characteristics.  What one(s) have you
tried?  If your internal net is 'NATed you'll definitely need some kind
of agent on the firewall in order to establish a VPN connection.

Yea, I've met those kind of people.  "within a couple of years" it isn't
usually Linux that is goes away; it's them.
