Wake On LAN (VNC) over the Internet (WOL)

If you wish to use Wake On Lan over the internet you will need to set up your destination firewall/router to allow "Subnet Directed Broadcasts". Most routers and firewalls disable this option by default.

You will then need to allow traffic through on your firewall/router on a specific port. The choice of ports is up to you.

While the topic is old, the subject is always of interest. The Draytek Vigor 2820 series routers (and presumably other models) have two relevant facilities:
1. You can establish a VPN from a remote machine directly to the router (this is an actual VPN connection, not pass-through to a VPN server running on a network machine).
2. The routers web setup supports Wake on LAN if the MAC address of the machine to wake is known (or the MAC address can be bound to a fixed local IP address, and the IP address used).

So you can wake up a machine on the network by establishing a VPN to the router, then using the router's WoL support. You can accomplish the same end by allowing password-protected Internet access to the router setup (less secure than VPN) and using telnet commands.

I do this - very useful.
