It's really late/early this morning and I was just checking the rule set
on a clients machine I just built. When I saw this:
65534 195 14104 deny log ip from any to any
65535 1 76 deny ip from any to any
Now maybe it's my lack of sleep but how did that amazing wonder packet
on rule 65535 sneak by 65534 :-) A fluke? A 1 in a million chance?
A posessed packet? This isn't exactly the kind of thing that instills
confidence in ones choice of firewall software :-)
It's ipfw BTW if you cant tell from the syntax, not ipfilter.
I have NEVER seen this happen before, so im guessing it's just a freak
accident. But it is curious nonetheless.
