Thank you, Quote: <<the local port and the remote port are two different things>> I am really getting confused. HostA is listening on 18002 and can still receive through 18001? I thought it is the unique distinction of sockets (IP and Port) that makes the difference?
HOST A HOST B ------------ ------ Listen 18002 nothing to send on 18002 Nothing to listen on 18001 sending RTP on 18001 to A Nothing to send at all nothing to listen at all So in my particular case above I am receiving on HOST_A_PORT_18002 datagrams from HOST_B (obviously through the RTP) with any random port numbers? Now I checked in Wikipedia that in the UDP header there is Source-Port and Destination-Port. But to which does it relate when I say : listen on 18002? (Source or Destination port of the incoming datagram?) Friendly Chris -----Ursprüngliche Nachricht----- Von: wkitt...@windstream.net [mailto:wkitt...@windstream.net] Gesendet: Sonntag, 18.
