Is it possible to Bridge (passing MAC and all ethernet traffic so no need to route IPs) on all three
ports (lan+wan+opt1) transparently?
I've successfully used the tips on this listserv to Bridge between OPT1 and WAN _OR_ LAN, but not
all three at once.

And, if bridging all three is possible, will m0n0wall behave more like an ethernet Switch (pass MAC
traffic to destination only) or Hub (pass traffic everywhere)?
