Different ports for listening and reading

Should I use different ports for listening and reading in a peer to peer application? If so, why not a single port for both listening and reading?

If you're talking about TCP, you don't get the choice: accepted sockets use the same local port as the listening port (and outbound ports have to use a different port, if you need them). If you're talking about UDP, there's no reason to use more than one socket, so no occasion to use more than one port. So the answer in both cases is the same: use one port.
