I have a web server that cannot be accessed on port 80.  It is in the same
rule with other web servers that can be accessed with no problem.  The
initial problem I was getting when examining the firewall logs was from
SmartDefense "TCP sequence validator: dropped with invalid ACK number".

I disabled sequence verifier under the TCP SmartDefense settings.

Now the message I am getting in the logs is "th_flags:10 message info:
Unexpected post SYN packet". Before the drop entry in the logs I see a
successful accept for the host attempting to access the web server on port
80.

I just recently migrated to Check Point NG FP3 on Linux from NG FP2 on NT,
before I migrated I was not seeing this problem.  Any help would be
appreciated.  Thanks!
