RE: [FW1] Unknown established TCP packet



The complete answer can be found on Lance's site
(www.enteract.com/~lspitz/fwtable.html).  It's not a good idea to just jump
in and implement the "fix" suggested in the link below, as the behavior is
by design.  Allowing non-SYN rulebase matches to be entered in the state
table (as was the default prior to 4.1SP2) exposes you to ACK or other
packet type floods.

Thanks as always to Lance for the info.
