You can define the port used on your game by setting the port on the "Transport Port" field.



Once defined, both transport systems ( OnlineObjectTranport and UnityTransport ) will use this port as a reliable and unreliable delivery method. Nonetheless, ObjectNet is flexible and in case your custom transport system needs different ports for reliable and unreliable messages you can define this by setting TransportPortType provided by ITransport interface ( see API reference for more information's ).
