Subject: TCP SYN FIN
Date: Fri, 02 Jul 2004 14:27:42 +0200	[thread overview]
Message-ID: <40E554BE.1010402@4Dllc.com> (raw)

Hi All,

I'm running Nessus to check my firewall rules, and its telling me :

"remote host does not drop TCP SYN packets with the FIN flag set .... "

I've tried adding the following rule :

$ipt -A INPUT -i $iface -d $network -p tcp --tcp-flags SYN,FIN SYN, FIN 
-j DROP

and a few permutations, but the warning still appears.

How do I fix this?

Best regards
Steve
