Answer

Problem

WOL is not starting the client machines

Environment

- All GFI LanGuard versions

 - All supported platforms

Solutions

Solution 1:

If you have routers between the client machine and the GFI LanGuard machine, the router and the GFI LanGuard machine must be configured to allow Wake-on-LAN broadcast packets on UDP port 9.

If there are no routers or if the problem persists check the next solution.

Solution 2:

Configure Wake-on-LAN on the client machine:
