Comment 8 for bug 125302

The script assumes that a bridge already exists and is the default route.

Adding this to the /etc/network/interfaces should get past this problem:

auto br0
iface br0 inet dhcp
bridge_ports eth0 eth1
bridge_stp off
bridge_maxwait 5

Replace 'eth0 eth1' with the physical interfaces you want in the bridge. In my cas

If the person who writes these scripts every reads this then for crying out loud put a comment in the damn things describing what you are trying to achieve please!!
