New specific Error code for port not allowed

[mikegorman-nf]

A failure of the port validation against the allowed range results in a ROUTER_ERR_GENERIC failure cause. It would be very useful to have a separate error code for this, as it indicates a misconfiguration, or an attempt to reach ports out of policy, possibly signaling malicious intent.
