the question is simple: i made a mistake in implementing
recv|xmit any, Oliver spotted it, i posted a fix.
Whether his example was a good one or not is rather irrelevant.
Hopefully the discussion has clarified that some checks
are redundant, but the compiler cannot possibly spot all useless

Yes, I also have a work-around with two rules, but I would
prefer an independend check within the "out" rule.

ok, so the problem is the following: when i implemented ipfw2
i thought that 'recv any' or 'xmit any' were effectively NOPs
so the parser erroneously removes them, together with any 'not' prefix
(which is processed before).
To fix this one should
- patch the function ipfw2.c:fill_iface()
so that

from the local host (i.e. non-routed) out through a
specific interface, i.e. packets that have _not_ been
received on some interface.
The manual page ipfw(8) says that "recv any" ma
18 matches
