RE: Strange behavior of Catalyst4006

I'm sorry I made a mistake the subnet between catalyst4006 and customer's firewall is

10.10.1.213/30,  Catalyst4006's interface address is 10.10.1.213, firewall's interface
address is 10.10.1.214. 


Sorry.

Joe

On top of that, we have this discrepancy:

So the router's address isn't even on the same subnet as the firewall's.
Again, it's not clear how it ever worked.
