Is it not possible to send a message with TIdUDPClient and then receive the
answer with a TIdUDPServer that is listening on a specific port?
I am using Delphi 7 and Indy 9
/HK

Yes, I dont know how to do it :)
I want to send a datagram to a remote server with TIdUDPClient, then that
remote server will send a reply back to me, but how do I tell the remote
server that it should send the reply on a specific port. The port I want the
reply on is the port I have set in the TIdUDPServer.
Right now when I send a datagram the port the remote server is told to send
the reply to is just a "randomly" selected port.

One immediately obvious way is to send the port number in the datagram.

I found a way, like this:
IdUDPClient1.Binding.Port:=12452; // or some other portno.
IdUDPClient1.Binding.Bind;
just before I call SendBuffer
