Thank you for the speedy response!
Regarding "Delphi Internet", I am referring to the UDPSocket component that
installed when I installed Delphi that resides under the "Internet" tab.
Sorry I didn't make that more clear.
I cannot see how to bind the ports using that component. I took a look at
the exposed methods/properties of TBaseSocket and binding is not an option.
The component has the localPort, remotePort properties, but setting them has
no effect.
Perhaps there is a way to bind after setting those properties, but I don't
see how.
Regarding the Indy UDP client:
I have attempted what you suggested, but still the source port is arbitrary.
Essentially, I just want to source and destination ports to be the same.
idUdpC.Binding.Port := 1020;
idUdpC.Binding.Bind;
results in the destination port being any number other than 1020.
idUdpC.Binding.PeerPort fails as it is a read only property.
Thanks again,
Craig
