hi all:

in my case, my physical machine has one ethernet, i want to use both bridge and nat network.

i create a bridge outbr0(addif eth0), when creating NAT network, there are 3 options for forward-dev

1.<forward mode="nat" />

2.<forward mode="nat" dev="outbr0"/>

3.<forward mode="nat" dev="eth0"/>

i do not know which one is the best?

thanks
