I have a machine that looks something like this:

fxp0 - public interface
fxp1 - private interface

I have natd running on fxp0, with ipfw diverting all traffic through natd.

If a packet comes in on fxp1 destined for fxp0, it goes through nat and
gets rewritten with fxp1's address, then gets sent back through ipfw
post-divert. At this point, is this packet still considered to be 'in via
fxp1'?

If a packet comes in on fxp0, gets rewritten by natd and ends destined for
fxp1, is it still 'in via fxp0'?

Thanks,

-----
