In the client bind the socket to port A, and in the client bind to port B. It's as simple as that. The server shouldn't really know A, but get it from the messages it receives messages from the client (using something like ReceiveFrom.

Remember that using UDP, the client has to be the first to send messages, otherwise it's not really a client-server system but more distributed system.

If you were using TCP rather than UDP as part of the constructor of the TCPClient you can specify which EndPoint you want the outgoing connection to use.

It's not possible to do this, since an endpoint consists of only one IP address and one port number. You would need to use two different sockets and establish two connections with the server in order to use port A and port B.

This is exactly how it happens already. The source port for a client is a random port chosen by the OS.
