      Hi there!

      I have recently been attempting to enable WOL for a few of my PC's in my network. The aim is for guacamole to send a WOL packet whenever it attempts to connect to certain PC's.

      At the moment, I have been able to send WOL packets from other PC's/phones. For example, I am using an app on my phone at the moment which can wake the PC up fine. However, with the same settings in guacamole I am unable to wake the pc.

      Could this be a port issue with cloudron blocking the default UDP port 9?

      FYI: If the computer is on, I can connect via RDP, just no WOL when pc is off.

      Thanks,
      Matt

        We don't block outbound ports but maybe we need some additional configuration to forward WoL - https://www.mail-archive.com/user@guacamole.apache.org/msg07125.html

        Not an expert but it seems WoL is sent as a broadcast - https://en.wikipedia.org/wiki/Wake-on-LAN#Magic_packet . This means that something has forward this WoL packet from the internal docker network to the external one somehow.
