Apologies if this is the wrong forum but it seems the closest to possibly helping us with our problem.
We have Internet service via cable (RoadRunner) and were having trouble with a VPN connection to one of our branch offices. The VPN would properly establish (to the public IP address), but we were unable to access hosts on the branch LAN.
The inside subnet at the branch is 10.32.0.0/16.
What we discovered is that RR was routing that subnet on the public side of our network. I did not think that it was permissible for an ISP to route private address spaces on the public side, but they claim that they can and do.
Now, I would have thought that our requests from remote client to VPN site would go through the tunnel, but somehow because RR is routing that private subnet it never gets there.
I agree with Paolo that in most VPN implementations the ISP does not see your priviate addresses and can not route them. Perhaps it would be helpful if you would post the configuration of the branch office device that implements the VPN? What is the branch office device that implements VPN?
Is it possible that your cable provider sold you a package (such as SoHo) that does not allow VPN usage? I know with some cable companies the lower end packages do not allow for VPN connectivity - just a thought.
