In addition to Andy's good suggestion, you should think about what the second negated rule would mean. "If the destination is not $D_INT and the source is not x.x.x.x, log this packet not exceeding 10 per second." The source is y.y.y.y, so your rule matches, and it's logged. The next packet is from x.x.x.x, so the rule does NOT match and is not logged. *Both* packets then proceed to the next rule. So then your next rule might be: -A AUDIT-RULE -d $D_INT ! -s y.y.y.y -m limit --limit 10/s -j LOG The packet from source y.y.y.y does not match and is not logged. But the following packet from x.x.x.x DOES match, and IS logged. Was that what you wanted? I bet not. You probably want something like another user chain, or maybe some RETURN rules before a blanket LOG rule at the end of this one, e.g.: -A AUDIT-RULE -d $D_INT ! -s x.x.x.x -j RETURN -A AUDIT-RULE -d $D_INT ! -s y.y.y.y -j RETURN -A AUDIT-RULE -d $D_INT -m limit --limit 10/s -j LOG -- http://rob0.nodns4.us/ -- system administration and consulting Offlist GMX mail is seen only if "/dev/rob0" is in the Subject: -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
