Cisco IOS Zone-based Firewall issue

Pradeep H A

Level 1

Hi,

Can anybody clarify if the line "received 25 packets out of order" in the show policy-map type inspect output correspond to the log about session being dropped due to invalid Seq# ? because I am not seeing packet drops anywhere else in our network... what might be the possible issue?

Thanks a lot in advance
