Looking to find out if this scenario is possible and if so, a little nudge in the direction I should look up to implement.
I have to Offices seperated by 40 miles. Branch A and B are connected with point to point fiber connection with an Ethernet hand off. For all intensive purposes, both offices function as one subnet.
I have MPLS Internet service in both offices. Branch A is the only one actually connected to the Internet. Branch B comes across the Point to Point for and goes out Branch A's default gateway(10.0.0.1). The Internet service in Branch B is directly connected to a video camera, for now. But that can be taken down anytime.
What I'd like to know, is it possible after connecting another firewall to Branch B, with a gateway of 10.0.0.2, to create a VPN tunnel to Branch A's firewall and have it work as a redundant connection in case the Point to Point ever goes down? Configuring the network to with the secondary gateway?
Both my Firewalls are Watchguard Core series.
Any help would be appreciated,
