My understanding from speaking about this with the Fed in the past is that yes, you would need to have a separate VPN set up from each physical location. So, if you wanted 1) the bank president to be able to access FedLine Advantage from home and you wanted 2) to be able to access FedLine Advantage from your Disaster Backup site and you want 3) to be able to access FedLine Advantage from the bank as usual, you'll need 3 VPN's set up. Part of me can't really believe that there's no other way to do it, but this is what our Fed support guy and our Fed rep told us.
The algorithms used by the Fed to allow/disallow access by token definitely take into consideration the physical location of the user, and the system will for sure "know" that the user is not in the bank.
Somewhere on FedLine Advantage there is a form to submit to make changes to VPN's and locations. You may want to look at that for clues. Good luck!
