Socket Destination Port Problem
Hi everybody,
I have an application where two different socket connections run in order to communicate with a machine. Over the first one (UDP) I send a request packet to ask for data and over the other one connection (TCP) I receive the data.
I repeat this procedure two times that is, I request a block of data and when it's finished I request a second one.By the first time it works without problems but by the second time I discovered with wireshark that the request packet is sent to another port (not over the original port). I know I haven't made changes between the first request call and the second one because I have a function where I initialize all connections at the beginning and it works for the first transmission.
Could the operative system change the destination port?
Can anyone help me?
Thank you very much
