Anybody could generate a magic packet, ostensibly from the server, to the directed broadcast address of the client's LAN, and wake up the client (if they know the MAC addresses, which is difficult from a remote location). Of course, it is not 100% secure because the broadcast (like almost all broadcasts) is connectionless. That will allow the server to generate the directed-broadcast and nobody else. Make a standard access list containing just the address of the server, and attach it to the ip directed-broadcast command. Yes, you can make this more secure by restricting the ip directed-broadcast on the client LAN to an access list. Once there, it will be transmitted as a broadcast, but only if ip directed-broadcast is enabled. This will be forwarded to the remote (V)LAN. (If there are several remote LANs, you need one command for each. If the computer is already awake then there’s no trouble connecting though. Went through the wake on LAN directions and attempted to wake w/both the team viewer id & public access. I am going to try the wake on lan on my local network and see if it works. I tried unassigning the computer then reassigning it. So on the (V)LAN where your server resides, you need an i p helper-address to the directed broadcast address of the (V)LAN where the client resides. Teamviewer has the option to send the wake on lan signal to a public address (I already set up the FreeDNS subdomain and everything) and I have my NIC set up through windows to accept magic packets. (If anyone knows otherwise, please let me know.) When a server is addressing a client on a remote LAN, I'm not sure whether it is intelligent enough to send its packet to the presumed directed broadcastĪddress of the remote LAN, but I assume not - I assume it broadcasts it splat regardless of its location.
It has to be a broadcast because a client in standby is unaware of its IP address.

Also see our article covering the best free Wake-on-LAN tools. Also, it’s a good feature to have on if you’re using the computer as a file server or game server. The magic sequence consists of six bytes of FF followed by the MAC address of the target, repeated 16 times. Wake-on-LAN is ideal to be used in conjunction with a program like TeamViewer or VNC. The server wakes up the client by generating a broadcast that contains, somewhere in the packet, a magic sequence.
