I am in no way an expert on bhyve (have not used it) so I am going to look
at this from a pure network standpoint.

A bridge is a layer 2 connection and is used to bridge two separate
networks over layer 2. That means they share the same IP subnet, but have
no other means of connecting together physically (note: to connect two
networks with different IP Subnets IE: 10.10.1.0/24 and 172.16.32.0/24 you
use a router since that is layer 3). So with an example like using
VirtualHost, when you add a VM and set it to bridge, you are telling
VirtualHost you want the VM to be on the same network as your physical
machine. Thus from the standpoint of the rest of you network, it "looks"
like it is a separate machine. It could even DHCP from your LANs DHCP
server and get a LAN IP if you wanted.

So your bridge needs to contain the physical interface you want to pass
traffic out on (like your wlan0 or lagg0). Then you add your bhyve guests
as taps to that bridge to get them access to the same physical network over
the bridge. You really do not need to set an IP on the bridge interface,
unless say for example you where going to bridge two physical networks
together on like em0 and em1. You would assign an IP to bridge0, not em0 or
em1 to be able to access/admin the server from either LAN.

I hope this helps some...
