[Plugin] OSC for UE4

Hello!
How to configure the receiving port on the client to exactly the same as when sending data?

What I mean:
I pointed out to the reception port 8000
I send data to :9000

On the server side raised node.js and node-osс.
I can see that the client has ip and port 64027 (each time a different client port is opened), so here I am on the side of the server can send back data on :64027 but the client is configured on port 8000 and the data can not be considered to the customer.
So the question arises, how to automatically substitute the client port on the wiretap data? in my case it has to be 64027 (same as the port and is set automatically when sending data)
