Assign an IP address to a bridge fail

[Pierre Dupond]

Hi all,

          I am facing a strange problem. Just after installing a fresh

Freebsd 12 on an Pc Engines APU machine, I build a bridge with the 4

network cards.


If I try to setup the address of the bridge in the "/etc/rc.conf" file,
I can not ping (outside the address

given to the bridge). But if I comment the line for setting the address
in the file

"/etc/rc.conf" and I set the address manually with the command

"ifconfig bridge0 inet 172.16.0.11 netmask 255.255.254.0" the ping works.

Do I have made an obvious mistake in the "rc.conf" file? What could be
the reason of this problem?

Any ideas would be greatly appreciated.


best regards,
