Greetings. There has been a recent thread (mine) on "questions" which has not been resolved - the last comment in this thread was from Doug White, "No Idea...". I need to know how to specify an ICMP subtype to IPFW, for instance, rather than killing *all* ICMPtype 3 messages using ipfw add 1 deny icmp from any to 123.123.123.0/24 icmptype 3 I need to kill only icmptype 3, subtype 11. How would I specify this? I have tried using icmptype 3.11, 3/11, 311, 3-11, etc... Thanks! J.A.
