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?
