I was looking for a good reference website for redundant OBSD transparent firewall setups and came across this website (http://seattlecentral.edu/~dmartin/docs/bridge.html). Although the document states that it uses 3.6 for the setups but I think it's still quite relevant and applicable. I've also searched through undeadly for any similar posts on this topic and found nothing, so I was thinking it might be useful to post this topic to undeadly as anyone might find it useful.
The article mentioned uses Cisco switches with STP as the fail over mechanism since CARP doesn't work with bridges. As well, using STP for fail over is not very timely (30 seconds to a minute minimum) but definitely another approach to the problem.
