Using a pair of PIX firewalls, OS ver 7.2, in a failover setup.
The outside interfaces of the two PIXes are connected to provider on two separate circuits.
Provider claims that in such a configuration, stateful failover does not work, and we need to hook up a switch (or a couple switches) between the pair of PIXes and the two circuits.
Somehow that doesn't ring true to me. I thought stateful failover has nothing to do with the way the outside interfaces are hooked up.
Which way is it?
Can somebody point me to a document that supports either one version or the other?
For how the firewalls should be connected:
