UDP is obviously a send-and-forget protocol. For example, during an NMap UDP scan, the only way to definitively prove that a UDP port is open is if you receive a response from that port. Keep in mind that many services may not reply to arbitrary data and require protocol or application-specific requests in order to warrant a response. When testing TCP ports, you can check with tools like nmap or nc only from the outside, but the nature of UDP is that it doesn't send anything back so you need to monitor the port on the receiving server to see if you receive any packets from the remote server. You can do this easily using tcpdump and nc. Ready to Probe. Our server is ready to send traffic to your computer. You may select either of two methods. If you would like to simply generate some event traffic on your computer to test the event notification dialog and see some events in the log choose the simple probe.

Port Checker is a simple and free online tool for checking open ports on your computer/device, often useful in testing port forwarding settings on a router. For instance, if you're facing connection issues with a program (email, IM client etc) then it may be possible that the port required by the application is getting blocked by your router's
