W2K > VPN tunnel > Linux > M$ Exchange

I have been digging around the internet trying to find info on what I am trying to do.

Basically I am trying to allow a VPN connection into our work network to receive emails from our M$ Exchange box.

We have a SuSe firewall that currently has ports 22 and 25 open. Port 25 has postfix checking emails and sending them onto the Exchange Server. Port 22 is currently used for Admin file transfers only.

My question is what software / settings do I need to open/configure on the Linux distro to enable VPN connections through to the Exchange server.

All I know at this point is port 1723 and protocol GRE come into it somewhere.
I have also seen something called OpenVPN that seems to use the SSL port 22 ?? Is this correct, or am I barking ... up the wrong tree!

Can anyone point me in the right direction.
