FreeBSD does not support bridging at the moment, but you can still configure it as a router between 10/100 networks. I have some bridging code available from my home page (compiles under FreeBSD, but it requires no OS to run -- either a .COM file or a ROM) which only supports "ed" cards (WD8xxx, NE2000, etc., both ISA and PCI). I am waiting for someone to add support for "de" cards (based on the 21x4x chipset) to netboot, at which point it will be straightforward to build a 10/100 multiport bridge. I have even tried to port the de driver myself but don't have enough time (and possibly, skill) to dedicate to this task.
