Accessing Exchange through site to site VPN with exchange on different gateway
We have recently setup a site to site VPN with 2 Cisco Pix firewalls. The VPN connection works perfectly. The problem we are running into is the the offsite users can't access their Exchange e-mail because the Exchange server is on a different gateway.
Is there a way that we can keep the Exchange server on its own gateway but allow the remote users to access the Exchange e-mail through Outlook?

The answer is yes, but we need more information to help. In the pix point the route to the Exchange.
The only way I can think this is going to be possible is via some heavy modification of the route tables.
You would have to put in a new route for the subnet of the other site to use the other gateway.
Drop in to a command prompt and enter
route /?
to see the syntax and help for the route command.
Use
route print
to see what the current routes are.

Ok let me lay this out a little.
Let's say I my subnet for my main office is 192.168.10.1/24 and my subnet for my new offsite location is 192.168.20.1/24. My default gateway for my exchange server is 192.168.10.240 and the default gateway for all other machines using DHCP is 192.168.10.250.

Are you saying I may need to add a route to all the machines on the .20 subnet to the exchange gateway?
Thanks
