Or, if you still want to use the VPN, you can do something like setup
a batch file (if its a VPN client capable of command line commands)
that will establish the VPN, then run the route command as follows:

route ADD <IP Address of Exchange Server> MASK 255.255.255.255 <IP
Address of local end of VPN tunnel> METRIC 1


That will force a route over the VPN to the Exchange server.  When the
VPN is killed, the route will go down with it.  This works nicely with
Win2k/XP/2003 and the built in IPSec/PPTP client, which can activate
connections via the command line.

This would allow you to keep the Exchange server behind the firewall
and not have to expose it at all to the web (and thus avoid any future
exploits directed specifically at it).
