![]() The received WOL Packet contains MAC Address 00E04C3103AC and empty password. The example below shows the packet sent from IP 192.168.1.4 to subnet-directed broadcast address 192.168.1.255 and destination port 7. Start your Wake-On-Lan tool which be used to send out magic packets. Start Wake-on-LAN Packet sniffer on the target (tested) machine.Last two ways requires configuration of the routers for each subnet. If the router or switch still has cached what port that computer is attached to, packet gets access to the machine. As the service uses UDP broadcast packets, it requires the source and destination. Unicast: the Packet sent directly to the machine IP address. Wake on LAN (WoL) allows to remotely power on PCs using a Magic Packet. ![]() The router or switch will forward the packet to all the machines on the subnet. Subnet-directed broadcast: the Packet sent to the target machine subnet.Limited broadcast: the Magic Packet sent to the limited broadcast address (255.255.255.255) it is received by all machines on the same subnet but not forwarded to machines on other subnets.There are three different ways to send Wake-on-LAN packets: This packet should contain a synchronization stream of 6 bytes of FFh and 16 times the repetition of the MAC address. The Magic Packet is a UDP broadcast message, that contains the Media Access Control (MAC) address of the network card of the target computer. Wake-on-LAN (WOL) technology is used for remote waking up machines from sleep state through special network packets (Magic Packet). Program will display all incoming "Magic Packets". It allows to check whether the target machine receive the packet or not. This will allow the usage of secure WoL magic packets even when the target device doesn't support this.Wake-on-LAN Packet sniffer is designed to troubleshoot and setup Wake-on-LAN in the Network. Otherwise the password will be stripped from the WoL magic packet. The password will be forwarded in the WoL magic packet sent to the device. For it to actually wake a sleeping computer, however, that computer must. If your device is configured for SecureOn you choose for "on". The WoL magic packet can be sent over a wireless network with no problem. SecureOn: Forward password to target device.The password can be either a string up to 6 characters or the hexadecimal representation of 6 bytes like for example f5e4d3c2b1a0. Format: IPv4 address or IPv4 address/subnet with a value between 8 and 32 or IPv6 address/prefix with a value between 8 and 128. If omitted or equal to 0.0.0.0 all IP addresses are accepted. IP address or subnet of the sender that is allowed to wake up the device.The Intel adapter allows 'Wake on Directed Packet', 'Wake on Magic Packet', 'Wake on Magic Packet from power off state', and 'Wake on Link'. To allow wakeup from powered-down state S5, wakeup on PME (Power Management Event) is also required. The devices that can be awakend are maintained in the Wake on LAN Gateway based on the attributes below: The machine's BIOS/UEFI must be set to allow Wake-on-LAN. We also advise you to define Wake on LAN access rules as this will ensure only WoL magic packets meeting the criteria will be broadcasted on your Local Area Network. When you have activated the firewall on your Synology NAS, make sure UDP port 19999 is accepted by the firewall. Wake on Lan (WoL) relies on a WoL enabled network card, we currently use Intel Pro 100 cards, and a motherboard with a WoL connector. Make sure your router forwards WoL magic packets to the IP address of your Synology NAS on UDP port 19999.
