Use a WoL Proxy for waking up thin clients

As of UMS version 5.02.100, you have the possibility to wake up thin clients even if they live in a different network which does not allow broadcast packets from the WAN. The trick is to set up one or more thin clients as Wake-on-LAN proxy. A thin client acting as Wake-on-LAN proxy will never fall asleep itself, as its job is to listen to a special wake-up call from the UMS. This wake-up call tells the Wake-on-LAN proxy to send magic packets to all thin clients or a selection of thin clients in its network. To support this functionality, the Wake-on-LAN proxy thin client must have IGEL Linux version 5.09.100 or higher.

For detailed information, see the Wake-on-LAN chapter in the manual.

To configure a Wake-on-LAN proxy:

  1. Go to UMS Administration > Global Configuration > Wake On LAN.
  2. Under Send the "magic packet to ...", choose the adress(es) to which the wake-up call shall be sent.
  3. Activate Wake On LAN Proxies.
  4. In the area below Wake On LAN Proxies, click on .
  5. Highlight the desired thin client in the left-hand column.
  6. Click on to select the thin client.
  7. Click on OK.

    The thin client will now function as a Wake-on-LAN proxy.

    A thin client that is configured as a Wake-on-LAN proxy can no longer be put on standby or shut down. This restriction applies as soon as the thin client receives the settings from the UMS.
