[Iptperl-general] Problem with tcp-flags - option

[Frank S. <fr...@sc...>]

hi all,

when i start my script i get the following error-message:

#############################################################
tcp-flags: field unknown at ./SITCo-Firewall line 320.
#############################################################

this are the lines, which causes the error:

##############################################################
%rule3 = ( %rule3, 'tcp-flags' => { mask => [ 'SYN','ACK' ] , comp => [
'SYN' ], inv => [ 'ACK' ]  } );

$filter->append_entry("OUTPUT",\%rule3) || die $!;
##############################################################

i tried many things and read the man-page serveral times, but i cant
find my mistake. Actually i try to find something similar to the
iptables-option "! --syn". Could anybody give me an Example.(I know,
this bitmask wouldnt make sense at all - it's only for testing the
syntax)

thanks for help

frank
