RE: [FW1] Fw: unknown established tcp packet



I ran into exactly the same situation when I upgraded to SP3. Check out http://www.phoneboy.com/faq/0408.html. As of SP3, the default is to drop packets for connections not in the connection table. Prior to SP3, it would try to match up the connection with an existing rule. The FAQ has you uncomment the line "#define ALLOW_NON_SYN_RULEBASE_MATCH" in fwui_head.def, and re-push the policy.
 
Now, if someone could tell me why the connections are falling out of the connection table so soon, that would help.

Subject: [FW1] Fw: unknown established tcp packet

Once again another e-mail titled unknown established tcp packet.  I have
looked through the list but I was not able to find a definitive solution for
this error.  Here is my problem after applying the latest check point
service pack (SP4) I began seeing my logs fill up with dropped packets by
rule 0 with the unknown TCP error.  Now I have customers telling me that
they cannot ssh, run restores, ect through their firewalls which upon
further investigation I noticed that all the packets were being dropped by
rule 0.  I am also seeing lots of in-bound packet to customer web sites
being dropped by rule 0 with the same error.  None of this was happening
when I was at SP 1 or 2.  Anyone out there have a solution for this????
