We have a remote office which connects to the main office over VPN; before setting up that VPN, people in the remote office could access services on the server in the main office using its public IP address or fdqn. Since setting up the VPN, the can no longer do so. I'm guessing its something to do with loopback or the public IP address of the main office server/modem being the same as the VPN's endpoint.

Any ideas?

(The reason we want it to work in particular is so people with laptops can work inside the remote office and outside it and access the things on the main office server using its public IP address/fqdn in both places.)

thanks,
