Monitor UDP Port

Our VPN (Mobility XE) uses UDP 5008 & 5009 to connect clients from the outside. I was trying to configure a PRTG probe to use a port sensor to connect to it, I just want to know that it is alive I don't need to login or anything. Anyway it fails because it is trying to connect to TCP/5008.

Is there a way to specify a UDP port?

I am sorry, the Port Sensor can only monitor TCP connections. Please consider writing your own script to monitor a UDP port, reporting the response time to PRTG. For more information on custom EXE/Script sensors, please see the user manual. For detailed information, see PRTG Manual: Custom Sensors.

Is this still accurate? Only way to monitor UDP ports is to use a custom script.

Will Paessler create a sensor than can monitor a UDP port? We would like to monitor our multiple tftp ports.

Probably not. As mentioned, the script sensors are the way to go here. Sorry!
