![]() ![]() It's important to remember that since this is typically sent over the data link layer, the target machine's IP address is irrelevant. This payload can be sandwiched anywhere in the broadcasts payload. The Magic Packet does not have to be exactly 102 bytes, but its relevant payload is. The packet is basically 6 bytes of 0xFF followed by 16 repetitions of the destination interface's MAC address (102 bytes total). Das läuft hier auf einem ProCurve 5406 fehlerfrei. The listening interface just looks for a Magic Packet with its MAC address encoded in the WOL scheme. Angenommen, du willst das WoL-Packet aus dem VLAN 55 (10.20.55.0/24) in das VLAN 11 (10.20.11.0/ 24) senden, dann musst du im VLAN 55 folgendes via CLI eintippen: conf t VLAN 55 ip forward-protocol udp 10.20.11.255 9 Die 9 ist der Port der verwendet werden soll. If you are looking for a tepid overview of the core components of this project in the form of a blog post: see here Magic Packets (of what?) Wake-on-LAN (WOL) describes a simple data link layer protocol which tells a listening ethernet interface to power the target machine up.Įach target system typically exposes a setting in its BIOS which enables or disables the system's WOL capabilities (since this can slowly consume a small amount of standby power). n.2.Wake on LAN magic packet generator for golang. Generate the magic packet from the server and the PC should wake up. ![]() Note: In this example with 'wakeonlan', the MAC address required to build the magic packet has to be reversed compared to the PC real MAC address (00:11:d8:12:89:17)įor more information, please look at the linux man page Linux wakeonlan command line used in this example: #3 : Static ARP entry to force destination MAC for the magic packet to be a broadcast #2 : Policy to allow general traffic to the PC #1 : Policy to allow the Wake On Lan "magic packet" using its dedicated IP Note : using the PC IP (instead of another IP) in the static ARP entry would work to wake the PC up, but this may break other traffic destined to the PC. Forwarding the packet as a broadcast is achieved with a static ARP entry with mac FF:FF:FF:FF:FF:FF. ![]() For this, we use a different IP address for the magic packet to reach the PC than the main PC IP address (choose an IP address not used on the PC subnet). The main problem is to get the magic packet forwarded as a broadcast once routed to get it recognized by the PC NIC. Packet is received from "PC to wake up" network interface and triggers the Wake on Lan startup. The Machines must be configured to respond to wake-up packets received by the network adapter and in the Machines BIOS. The WOL packet is received from the FortiGate DMZ and routed to "PC to wakeup" as an Ethernet broadcast. "Server" sends a Wake On Lan Magic Packet to "PC to wake up". This is the particular case which is discussed here. In some cases, a unicast destination IP can be used which makes the routing straight forward, however most generally the destination MAC of the magic packet must be a broadcast which causes a routing problem. There are different types of Magic Packets that can be used depending on the NIC manufacturer and driver. This requires the PC network interface and BIOS to support WOL. The idea of Wake On Lan (WOL) is to trigger the "wake up" (boot-up) of a device from the LAN via a specific Ethernet packet called 'Magic Packet'. This example is based on broadcast type of Wake On Lan "magic packet". This document provides an example of how to configure the FortiGate to route "Wake On Lan magic packet". ![]()
