This article guides you on how to set up Wake-on-LAN on a Windows operating system for the GFI LanGuard to wake up the target machines.
The motherboard and the network interface card of the computer running GFI LanGuard must support Wake-on-LAN.
Wake-on-LAN (WoL) is an Ethernet computer networking standard that allows a computer to be turned on or woken up by a network message. WoL enables GFI LanGuard to wake machines from the following states:
- Powered off
This is done by the GFI LanGuard sending a message to the same local area network or to another network by using Subnet directed broadcasts.
IMPORTANT: If you have routers between the client machine and the GFI LanGuard server, the router and the GFI LanGuard server must be configured to allow Wake-on-LAN broadcast packets on UDP port 9.

For some network cards, it may be necessary to configure additional settings in the Advanced tab. For example:
NOTE: refer to your network card provider technical manual and support for more information. card.
