stateful inspection

[carl_townshend]

Hi all, with the asa firewall, does it perform stateful inspection both ways, i mean inside to outside, and outside to inside.

Are you talking about the 'regular' L3/l4 state table maintained by the firewall? or the Deep packet/Applicaion inspection.

The first one is both ways, meaning any traffic that is allowed to go back is allowed to come back in. Similarly any traffic coming from outside (that is allowed in) will be allowed out (as long as the traffic is part of the same flow).
