natd + ipfw question

[Leo Bicknell]

Can someone explain to me why:

ipfw add 1000 divert natd ip from any to any via fxp0

works, and yet:

ipfw add 1000 divert natd ip from any to any recv fxp0
ipfw add 1001 divert natd ip from any to any xmit fxp0

doesn't?  Yes, I want to do something fancier treating inbound and
outbound traffic differently, but this basic case doesn't seem to
work, and it seems to me like it should.  What am I missing?
