If you've got windows at one end, and linux at the other, using OpenVPN is probably your best bet.
This looks to be the way I need to go, but I've not got a lot of experience with OpenVPN and know that it's very flexible so I need pointing in the right direction.
I guess what I want is for my mail server to be an OpenVPN server (is it client/server?) and for the Windows boxen to connect to the server via whatever method they like. What I need, though, is that each Windows box always gets the same IP address on the VPN, and that different Windows boxes cannot talk to each other through the VPN (as they'd be different client's boxes).
Where do I start, is this quite straightforward?
OpenVPN (http://www.openvpn.net/index.php/open-source/overview.html) and Shorewall [iptables wrapper] (http://www.shorewall.net/) are probably where you need to start; they work happily together and the documentation is both excellent and mutually supportive.
There is a GUI for OpenVPN that runs on Window$ making a connection in for road warriors (which is effectively what the Exchange box would be when your mail server is an OpenVPN server) beyond trivial. You can find it at http://openvpn.se
There's a learning curve ahead, but lots of how-tos and tutorials on the respective web-sites. Good luck!
I'm sure there are others on this list apart from me who can do this, so ask away if you have problems.
Cheers, Laurie.
