Hi Jean/Ramakrishnan,

           I have one query regarding NAT poke packtes.Currenlty I am
working on enhancement of RTSP client module for Motorola phones.For some
networks,after initiating streaming all the UDP/RTP packets sent from the
server are blocked by the network.It is observed that after disabling
sending NAT packets ,the network is allowing UDP/RTP packets to reach

Could you please tell me why network allows UDP packets after disabling NAT
packets sent from the client.what is the significance of disabling
sending NAT packets.

I appricaite your help.
