Hello,
I'm using FreeBSD 7-STABLE. I have 6 NICs as a bridged interface, one =
of which is a ath0 wireless NIC. I don't understand if this acting the =
way it should. If I try to dhclient on interfact ath0 I'll get the =
request no problems. But if I dhclient to bridge0 interface, it acts =
like there's no server - Even though its bridged. Also note if I =
connect a cable to any of the wired NICs, dhclient will then work on =
bridge0 interface.
The setup is kinda complicated, but i'm hoping someone may have a =
different view on it. One thing that confused me is that the line in =
/etc/rc.conf ifconfig_ath0=3D"WPA" - it does not matter if this line is =
before or after the bridge declaration.=20
