I have 2 3260 Palo Alto firewalls in 2 data centers. I configured GRE tunnels between 2 Arista Switches and they are in front of Firewalls. I configured OSPF routing protocol. All prefixes are learned by OSPF. Both Firewalls can ping each other of management interfaces. GUI and SSH are not working remotely. I researched but not able to find the right solution. Please reply if you have any solution for this issue.
