Can dsp.UDPSender work over a network?

Hello,

I'm trying to get dsp.UDPSender to send a message to another computer via UDP in real time. However, I'm having trouble using dsp.Sender/Receiver. My code is as follows

Sender computer

i=0;
send=dsp.UDPSender('RemoteIPAddress','www.xxx.yyy.zzz')
for i <30
  info=uint8(255*rand(1,32));
  step(send,info);
  i=i+1;
  pause(.5)
end
release(send)

Receiving computer

udpr=dsp.UDPReceiver(remoteIPAddress','www.xxx.yyy.zzz')
step(udpr)

while the sender is in the loop, im spamming the receiver's step call. However, all i recieve is an empty 0-by-1 matrix. both IPs are the same (sender computer's IP address). Both have LocalIPPorts of 25000. Can someone please help me to get this workig!

I do not see at the moment where you are defining the destination port number?

Have you tried something like WireShark to see what packets are going out?

It may be necessary to run Matlab as an administrator if you are not seeing any network activity.
