UDP Port Scanner by DroidVPN allows you to discover which outgoing UDP ports are open on your network.

This app is usefull if you are connected on a very restrictive network because you can check what UDP ports are still open on your network's firewall.

How it works? The app simply sends UDP packets to our server and monitors if it will receive a reply for a packet that is sent on a particular port.

NOTE: If you are getting too many list of open ports then it means you are scanning on a network that already has those ports open. You should only scan when you are connected on a restricted network.

Its not the fault of our app if it cannot find an open port. Our app is merely a tool to check for open ports it will not magically open any port for you.
