ipfw with nat - allowing by MAC address

[Lubomir Georgiev]

  OK people - here's the deal. I have tried the setup as described by *Patrick
Tracanelli at *click
<http://lists.freebsd.org/pipermail/freebsd-ipfw/2007-April/002956.html>
but the shitty thing still doesn't want to just let it be! Since I don't
want to

00500   468   30071 deny log logamount 100 ip from any to any MAC any
any layer2 via xl0


  I'm trying to integrate a rule that just skips the natd but still allows
normal client -> freebsd box communication. The problem is -   I can
manipulate layer2 any way I like e.g. use skipto with MAC as described and
everything but as soon as I add a rule like this

ipfw add 500 skipto 1400 /after the divert natd/ all from any to any not
layer2

  I lose worldwide connectivity. And if I don't add this rule my whole
192.168.1.0/24 segment in enabled because of the

01203 divert 8668 ip from 192.168.1.0/24 to any out via fxp0
01205 divert 8668 ip from any to me in via fxp0

  Can someone please explain this? And just give the word and I'll send a
more substantial part of the ruleset and the different strategies /of
rulesets :)/ that I've tried.
  The bottom line - Patrick's setup doesn't work, at least here. I'm certain
that I've written the rules they're supposed to be /just change ip ranges,
if names etc./

  10x in advance and please do bare with me...
