I've made test with very simple iptables rules (after flushing all rules 
filter / mangles and also tried a reboot) :
iptables -F INPUT
iptables -F OUPUT
iptables -F FORWARD
iptables -A INPUT  -j QUEUE
iptables -A FORWARD -j QUEUE # (not needed this is a direct connection)
iptables -A OUPUT -j QUEUE

I still can't connect with ssh, but can i see an established connection 
on port 22 when looking in /proc/net/ip_conntrack

BTW, kernel is 2.4.27 / iptables 1.2.11 with some patch-o-matic 
extension applied.

Any ideas ?

Regards

Laurent
