VPN / ISP redundancy architecture Hello, I am working on a solution with high-availibility and I would like to be sure about VPN and ISP redundancy. If I have a firewall A with 2 ISP (primary link with ISP1/backup with IPS2), and a VPN with a firewall B, do firewalls A and B have to be managed by the same SmartCenter for the VPN/ISP redundancy to work ? If a link fails on firewall A, how firewall B will know that it will have to go through the ISP2 link on the Firewall instead of ISP1 ? As the Firewall A will have 2 public addresses, how will Firewall B learn the second IP address as the object is defined with 1 IP address ? Can this work if the 2 Firewalls are not managed by the same smartCenter ? If both Firewall A and B use ISP redundancy, will the VPN redundancy still work ? Do I have to use interface VPN with dynamic routing for the redundancy ? I realize this is a lot of question but I would a have a best understanding on how this works exactly to implement it.
