Re: WLAN and Bridge

hi,

Yes and no.

Yes, it's another 802.3 interface.

No, not in STA mode, because in STA mode the only MAC address that can be
used is the MAC configured /for/ the station. You can use >1 MAC in
hostap mode and in WDS (4 address mode); however neither of them will do
what you really want (which is your wifi NIC to be a STA, and a bunch of
MAC addresses also work behind it.)

(Yes, this is what WDS is for, however no APs support it out of the box for
random clients.)

You'll need to setup a bridge interface for your bhyve VM tap interfaces
and then do pf/ipfw NAT.
