How to make NFQUEUE ?

Hi all,

Some days ago, I present a question and I been oriented to NFQUEUE.
Ok ... but how does it work ?

Really strange behavior.



Data :

I said : "~# iptables -I INPUT -j NFQUEUE".

So, I suppose that I will have all packets of INPUT filter table playing
with NFQUEUE : am I wrong ?

Next, I rely this to some example programs in order to ACCEPT the
packet, like from net-perl-bindings : I made a network mirror like.



Questions :

First, not all packets get through NFQUEUE : with perl and more
dramaticaly with C too.

Second, not all packets get the policy ACCEPT, so my browser don't get
images ... but only text, perfectly indeed. Is there a way to get ACCEPT
on an handler that have no lenght ?

If someone know about this, I would happy to read an HowTo.

Thanks, best regards.
