umm well should it? you're sending everything to the QUEUE table but do you have 
a rule in the QUEUE table telling anything to move on past the QUEUE table?

ughhhh... actually it does to me... i don't use any kind of inline or iptables 
rules for snort in my installs and it detects traffic and alerts on it quite 
well... perhaps you are confusing methods of operation? or perhaps there's some 
specific confusion being thrown into the equation somehow from somewhere?

my snort installs read the rules and sit and alert... they do not attempt to run 
in iptables more or use the iptables blocking methods... my snorts simply read 
the packets and sound alerts in their alert files... i think the KISS principle 
plays a large part in this aspect ;)
