In my case, you may need multiple simultaneous connections between computers A & B, so each client will need its own port. i think i'm going to use one port to accept connection requests and it'll respond with the port that should be used.
Not intended as criticism of your design, just for information: multiple connections between the same client and server computer do not require multiple ports on the server. The client will use multiple ports - one per connection - but you don't have to worry about that, the operating system takes care of it. You can open multiple connections to the same port on the server regardless of whether the source is one computer or several. I think the multiple ports approach will be more complicated, you'll have to worry about issues like what to do if a client connects, receives a port number, and then never establishes a connection on that port - will it hold that port open, listening forever for a connection?
