Hi I've set up VPN through SBS4.5 so I have a dedicated server running my
VPN server. The SBS server has two nic cards one for the internal stuff and
the other for the external VPN and SMTP server.

What you need to do is to certainly put two nic cards in the PC that is
going to be the server.

One of the nic cards needs to be assigned an external address - and you
associate the VPN server to that address and plug it into your router so the
world can access it. You should stealth this address so that only known
machines can get to it.

I hope this points you in the right direction.

Regards

Kev
