I don't think you can achieve that. NORMAL action will only work on
ports of a bridge.
There are some options that I can think of (whether it is of any use
to you, depends on your use case):
* You can create a tunnel on the bridge such that the remote_ip of the
tunnel is reachable via your third port. In that case, your remote end
point should be capable of decapsulating the tunnel header.
* You can create another OVS bridge and attach the independent
interface as a port of that bridge and then use a patch port to
connect them. You can also use a veth pair like openstack does.
