That's not how "real" bridges/switches work. (I yes they don't have to.

Even bpf complains, moderately, if the interface does not have an address ... cheers luigi > > should probably go search the archives, as this has surely been > > answered before.) > > They don't - they just have to be up'ed. > > bashir:~$ grep ifconfig /etc/rc.conf > ifconfig_tx0="inet bashir/28" > ifconfig_tx1="up" > bashir:~$ grep bridge /etc/sysctl.conf > net.link.ether.bridge=1 > net.link.ether.bridge_cfg=tx0:0,tx1:0 > net.link.ether.bridge_ipfw=1 > > > -- > David Siebörger > drs@rucus.ru.ac.za > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-net" in the body of the message To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
