How can I check UDP connection to other server?

My network dep. telles me that they have opened the FW but my application still can not get through to other server. If it was TCP I could simply test it myself with "telnet", but how can I check it when the connection is UDP?

UDP is connectionless, so there's no way to tell whether it gets through except the normal response from the server. By connectionless, I mean that each UDP data packet is sent individually and separately, like tossed paper airplanes Smilie There's no setup phase like TCP, you just send and it either works or not.
