Thank you,

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?)

should be able to use any local port to send to hostA on 18002... if hostA
is to respond to hostB, then hostA can also use any local port to send to
hostB on 18001...
