Zone based firewalls
Posted on 2011-02-18
I am new to the world of firewalls... and going over the ZBFWs. I am not sure what is the motive for creating such a FW, I see am example where the INSIDE and outside are grouped as int zones and the traffic is inspected with policy maps, all within a router. Well, all this could be done with prev int based ACL rules. What is something that is pushing for the need to have ZBFWs.
