What I am missing?

You cannot bridge the tap and wlan device.
This only works with fixed ethernet devices. What you can do is set up
NATing with pf / ipfw so your bhyve VMs are "behind" your host.


Why not? The handbook doesn't say that only specific devices can be bridged?

I tried to set up the network following this guide:

http://www.krizna.com/centos/how-to-setup-network-in-centos-6/

The dhcp option didn't work (can't obtain the IP). When assigning the IP 
statically the network can be started but then only the host is visible. 
Neither the DNS nor the gateway are visible:
