I noticed in my pf.conf that I had "set skip on lo".

I changed that to "set skip on lo0" (still advisable), and then created
an "lo1" using

  ipv4_addrs_lo1=127.1.0.1/24

in my /etc/rc.conf, and I can now route in and out just fine.

I don't know if ipfw has a similar "don't apply rules to lo0" option,
but if that's the case, create an lo1 instead.
