You need a -current kernel from 20010817 or later with `pseudo-device
bridge', and you will need to build brconfig.

To use, simply configure the bridge0 device with `ifconfig', then add
interfaces with `brconfig'.

I did this quite happily with 1.5 userland, but there are other tools
that need to be updated (such as gas) to build -current kernels on 1.5.
Alternatively, you could grab one of the latest snapshots from and install that,
it has everything ready to go.

As I understand it, filtering on a bridge with ipf is not yet possible
(someone please correct me if that is no longer the case).
