PSENscan Configurator can't find devices over VPN

Problem

Using PSENscan Configurator software to scan for devices, like the Pilz Safety Laser Scanner, finds no devices over VPN.

Cause

Some software programs are compatible with UDP broadcast relay. However, this software scans for devices using a method of broadcasting that is not supported over VPN.

It broadcasts to 255.255.255.255. This broadcast address can only be used in local networks, as described in the internet standard RFC 919. Meaning the software is developed for local use only.

Solution

Unfortunately, this method of finding devices is incompatible with VPN connections.
