This includes a network card that isĬapable of receiving the WOL signal, as well as the appropriate software to In order to use WOL, a computer must be equipped with the necessary hardwareĪnd software to support the technology. Large number of computers that need to be turned on and off at specific times. This can be particularly useful for individuals orīusinesses that need to access a computer remotely, or for those who have a Wake on LAN (WOL) is a technology that allows a device to be turned on remotely Possible that you would need to set broadcast-forward to enable for this to work as well.Cisco IOS - Wake on LAN (WOL) not working anymore Wake on LAN 192.168.10.255) and an arbitrary destination port should get you what you wanted. If you definitely can't directly route to the destination for one reason or the other, creating a UDP port forwarding rule from the reachable interface at an arbitrary port to your designated network's broadcast IP address (e.g. Using port forwarding to a broadcast address E.g.: your client subnet is 192.168.10.0/24, you would generate a WoL UDP packet to 192.168.10.255 and get it routed, your last routing hop would send it as a broadcast over the interface connected to the 192.168.10.0/24 network.Īccording to the reference documentation, FortiOS command for enabling directed broadcast forwarding would be config system interface edit set broadcast-forward enable 2. Routing a directed broadcast packetĪ "directed" broadcast would be a packet destined for a foreign IP subnet which would be addressed to that subnet's broadcast IP address and sent out as a broadcast by the last hop in the routing path. You also would need to configure your Fortinet router accordingly using one of these choices: 1. For Windows, Gammadyne's wol.exe would do pretty much the same. Many utilities available would just send a raw Ethernet frame to a local network so they would not meet the requirements.įor Linux, there is the wol utility which can do this. Generation of UDP WoL packets would require a utility which is able to craft a packet with a specific destination address. As you need the packet routed, the UDP protocol is the obvious choice - it is encapsulated in IP and thus routable, it is connectionless and thus broadcastable. WoL is quite protocol-agnostic, so basically any broadcast frame meeting the specific criteria would do. How to generate a WoL packet destined for a foreign network The generating host does not have to be your machine - it can be any host capable of sending packets to the destination network. I have no experience with Fortinet gear, but if the WoL Packet generation is unsupported by the router in question, the commonly taken approach would be to generate the packet on a different network and let it get routed to the destination. ![]()
