I am working on a project where we just implemented a new Layer2 P2P connection between two of our locations. Currently all the routing and everything is done on one Sonicwall at the main office. We have a second Sonicwall and an Internet connection at the remote office and now we need to setup the second Sonicwall at the remote location.
How can I set this up so traffic primarily goes over the P2P connection and has a failover option to go over a Site-to-Site VPN tunnel?
