The dhclient.conf does not contain any interface configuration values
unless you write it. dhcp automatically reads dhclient.conf on startup,
so you just need to enable dhcp for the interfaces you want configured.
In rc.conf insert
interface_ath0="DHCP"
interface_bge0="DHCP"
Create dhclient.conf like this
interface ath0 {
default {
... the default configuration for your wireless nic ...
}
}
interface bge0 {
default {
... the default configuration for your wired nic ...
}
}
No need to mention any scripts in dhclient.conf. In the default
configuration you need to specify at least: ip address, netmask, router
and nameserver, see dhclient.conf(5) for the names of those variables.
You only need to create an interface specific section if you need to
configure the nic with values other than those provided by the dhcp
server. If your ath0 is always configured with dhcp (as I understood)
and you are happy with that, no need to make that section in the
dhclient.conf - or keep it empty.
Then run
# /etc/rc.d/netif restart
Cheers, Erik
