> The simplest way to do it is just setup both ethernet ports into a bridge:


ip link add *br0* type bridge
ip link set *br0* up
ip link set eth0 up (or whatever your ifnames are)
ip link set eth1 up
ip link set eth0 master br0
ip link set eth1 master br0

With this, both ethernet ports will get DHCP from your existing router.
