Besides having multiple nics or bridging the container with the host's
eth0, you can also simply forward the ports you want to the container.
If only one container will use a given port on the machine then you can
forward port X on eth0 to port X on the 10.0.3.$(container), else you
can use custom ports.

(Or use ipv6 :)
