If it is, I see no rule like : # iptables -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT Which might help to accept incoming packets that are a reply of an outgoing packet. If it isn't, it could be that you have set policy to DROP for the OUTPUT chain and have to ACCEPT rules for the OUTPUT chain : netfilter will not let any (locally generated) packets out. To check : if you start the service, type : # iptables -P OUTPUT ACCEPT and then try to ping or something. Gr, Rob
