after boot mounts your partitions the network should be initialized
and if you have ifconfig_nic="DHCP" in your rc.conf dhclient should
look for a dhcp server first and probably gets an answer. If you
didn't daemonized the dhclient process it should stay until timeout
or getting the IP address and then run the rest of network setup.
So almost for sure dhcp goes first but is not getting an answer within
time and you do not noticed it.
May be your timeout in dhclient.conf is too low if your network
performance is poor. Or you may try increasing your retry value
may be you have an intrface problem and the -w option could be useful
for you or you consider configuring interface NIC { } in your
dhclient.conf
BTW what fbsd version are you referring to?

does not make so much sense starting ipfw before the initial network
setup what invokes certainly dhclient first if set ...
