It seems that I cannot get IPFW to work (no doubt due to a lack of knowledge of PPP and it's associated protocols). I have used similar rulesets with Ethernet NICs, no problem. I've done an "ipfw add 5 allow lo all from any to any", and I see entries like this in the log, which I suspect might have something to do with my problem: > /kernel: ipfw: 5 Accept P:88 209.212.118.85 224.0.0.10 in via hdlc0 Can anyone explain what P:88 is, and how to construct a rule to accept/reject it? Also, why is the destination address 224.0.0.10 - That's a multicast address if I am not mistaken? You can tell that I'm a little out of my depth here - any help would be much appreciated.
