Bridge, dpcpd, sshd

Hi all,

I have a server machine that I use as DHCP server, sshd login etc, and since I have multiple Ethernet interfaces on it, I would like to use two of those for the internal network to avoid adding one more ethernet switch for just one extra machine. DHCP should configure hosts on both those interfaces and all the hosts should be on the same subnet. 

So, I set up a bridge interface as per the FreeBSD handbook (ch. 31.5), but now dhcpd is refusing to start during boot as it claim that the "bridge0" interface doesn't exist. If I manually start dhcpd with the same parameters after the machine has come up, it will start and it will also work as expected and assign addresses to users connecting from teh bridge interface.

sshd seems to do something similar, it refuses to start, but can manually be re-started later on.

Is this some kinf of expected behavior, or does it sound like I'm doing something badly wrong? Can I force bride0 to be configured earlier in the boot so it is always there when the daemons start waking up?

Configuration info below.


===== rc.conf extract ====
ifconfig_bridge0="addm dc0 addm dc1 up"

===== sshd.conf extract =====

=== the dhcpd.conf is quite standard and does not say anything about the interfaces, that info is in rc.conf above ====

=== /var/log/messages extract ====
 dhcpd: bridge0: not found
