I have want to send message in UDP mode to a remote device(which has a ip address) from a s60 device(I'm haveing a E51 with a 3G enables SIM card).

I'm starting a 3G connection using the RConnection Class(the connection is getting started). I'm opening a UDP Socket and sending the message through this socket. But I'm not able to receive the same at the remote device..

I tried sending to the same device frm which I'm sending by creating another socket which listens on particular port. I can receive the message when i give the address as ''. But when I give the ip address, I'm not able to receive the message.

Can anyone tell me why i'm not able to receive the msg? I tried sending 10-15 times but never got anything on the listening port
