I don't understand where you want to go... If I have no iptables rule, 
all is OK as I say in my first message. The problem is I use iptables to 
do state filtering and all FIN / RST packet are seen as INVALID (instead 
of ESTABLISHED...).

The solution mustn't be to remove iptables rules ;)

Nobody have this problem ? I think this behavior can be observed on all 
directors with iptables... (I run
2.6.18-4-686-bigmem on Debian machine with iptables 1.3.6.0debian1-5 and 
keepalived 1.1.13-1)
