I'm looking for a firewall appliance that supports high availability and spanning tree.
I have two ha-cluster nodes and I'd like to protect them with a firewall. To avoid a single point of failure, I'd like to have two ha-capable firewalls. And since I need redundant switches too the firewall must support the spanning tree protocol.
My preferred setup:
+------------+ +----------+ +--------------+
lan 1 --| firewall 1 |--| switch 1 |--| ha cluster 1 |
+------------+ +----------+ +--------------+
\/ |
/\ |
+------------+ +----------+ +--------------+
lan 2 --| firewall 2 |--| switch 2 |--| ha cluster 2 |
+------------+ +----------+ +--------------+
