What is the reason why if i use this iptables:
> # (APACHE)
> $IPT -A INPUT -p tcp -d x.gabrix.ath.cx --dport 80 -m state --state !
> INVALID -j ACCEPT
> $IPT -A INPUT -p tcp -d tor.gabrix.ath.cx --dport 443 -m state --state
> ! INVALID -j ACCEPT
the hostnames you see get resolved to their pubblic ips.This is on an
inside lan pc but this doesn't happen on the gateway pc right before it
where iptables says it can't resolve the hostnames .Why this ?I have
debian sarge kernel 2.6 on all machines.
Thanks !

What is the DNS for the gateway? Have you allowed the gateway to send
DNS in the OUTPUT chain? - John
