Hello

I'm wondering if state doesn't apply to ICMP packets.

iptables -A FORWARD -p icmp -m state -d 1.2.3.4 --state NEW -j ACCEPT
iptables -A FORWARD -m state --state NEW,INVALID -j REJECT

if I ping 1.2.3.4 the echo-reply is blocked from 1.2.3.4. Is this normal, I
thought that the echo-reply should be marked RELATED and therefore not
blocked?
