If it doesn't work *at all*, you might have forgotten the rule to accept incoming connections if they're part of an established or related to an established connection, something like this: iptables -A INPUT -i interface_to_the_internet -m state \ --state ESTABLISHED,RELATED -j ACCEPT If sometimes it works and sometimes it doesn't, then it's *probably* not related to your iptables setup. If you think it's the fault of iptables anyway, you might want to post your iptables rules.
