Thanks, Leonidas.

The bridge.ko is loaded via /boot/loader.conf, and both
bridge.enabled and bridge.config are set via /etc/sysctl.conf

bridge_ipfw is set in my script that was shown in the original
e-mail.

dummynet.ko is also loaded via /boot/loader.conf.  I believe I
have all the necessary ko's loaded and configs set.  Otherwise,
the second pipe wouldnt have worked.

Yes, I loaded the ko at start-up.

This thing just seems strange to me.  Maybe there is something
about bridging that I don't understand.
