Hi, I'm trying to follow the advice fount in the handbook by configuring the IP address on the bridge0 interface rather than on a member interface. Then I've configured my rc.conf like that: cloned_interfaces="bridge0" ifconfig_bridge0="addm bge0 addm xl0 DHCP" ifconfig_bge0="up" ifconfig_xl0="up" But, with this configuration, the dhclient didn't start automatically on the bridge0 interface. After a reboot, my bridge0 status is: [olivier@d630]~>ifconfig bridge0 bridge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 ether 82:03:c8:73:85:cc id 00:00:00:00:00:00 priority 32768 hellotime 2 fwddelay 15 maxage 20 holdcnt 6 proto rstp maxaddr 100 timeout 1200 root id 00:00:00:00:00:00 priority 32768 ifcost 0 port 0 member: xl0 flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP> ifmaxaddr 0 port 5 priority 128 path cost 55 member: bge0 flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP> ifmaxaddr 0 port 2 priority 128 path cost 55 I need to manually start the dhclient on the bridge0 for getting my IP address: [root@d630]~#dhclient bridge0 DHCPREQUEST on bridge0 to 255.255.255.255 port 67 DHCPNAK from 192.168.100.254 DHCPDISCOVER on bridge0 to 255.255.255.255 port 67 interval 6 DHCPOFFER from 192.168.100.254 DHCPREQUEST on bridge0 to 255.255.255.255 port 67 DHCPACK from 192.168.100.254 bound to 192.168.100.58 -- renewal in 432000 seconds. I'm ussing current: [root@d630]~#uname -a FreeBSD d630.freenas.org 8.0-CURRENT FreeBSD 8.0-CURRENT #14: Thu Mar 12 14:17:22 CET 2009 root@d630.freenas.org:/usr/obj/usr/src/sys/DellD630 amd64 What is the good rc.conf parameters for using a dhclient on a bridge interface ? Thanks, Olivier
