I'm not proof in firewalling, but with this line, I'm adding a rule to table OUTPUT in witch I've no restricion. I don't think this could help me; but I could be in wrong too ;).

My trouble is why on an interface I can receive a ping (ppp0) and not on an another (eth0) if I've not added an interface specification to the rules?
