I think we are confusing ourselves with Stateful Packet Filter vs. Stateful Failover.
Stateful Failover, IIRC, is exactly for the 'higher layer protocols' ... maintaining sessions, etc. Thanks!

I would think that stateful inspection at the application layer would be doing the same...(at least....maybe even extra stuff) So if you have an smtp session open through a device that had statefull inspection enabled for the application layer, then it would track the actual communication and not the session per se....of course... It would almost seem weird to have stateful inspection in the higher levels without layer 3....things that make you go hmmm..... Tiem to go do some research...hehe -Patrick >>> "Steven A Ridder" 02/28/02 12:17PM >>> I think it means the ability to check other layers such as 4-7.
