==Wake on Internet==
{{See also|Bonjour Sleep Proxy}}
The originator of the wakeup signal (magic packet) does not have to be on the same [[local area network]] (LAN) as the computer being woken. It can be sent from anywhere using:

# A [[virtual private network]] (VPN){{snd}}which makes the originator appear to be a member of the LAN.
# The Internet with local broadcasting{{snd}}some routers permit a packet received from the Internet to be broadcast to the entire LAN;<ref>{{cite web |url=http://portforward.com/english/routers/port_forwarding/routerindex.htm |title=Router Port Forwarding Guides |work=portforward.com |access-date=28 October 2015 |archive-url=https://web.archive.org/web/20151104035214/http://portforward.com/english/routers/port_forwarding/routerindex.htm |archive-date=4 November 2015 |url-status=dead}}</ref> the default TCP or UDP ports preconfigured to relay WoL requests are usually ports 7 ([[Echo Protocol]]), 9 ([[Discard Protocol]]), or both. This proxy setting must be enabled in the router, and port forwarding rules may need to be configured in its embedded [[firewall (computing)|firewall]] in order to accept magic packets coming from the internet side to these restricted port numbers, and to allow rebroadcasting them on the local network (normally to the same ports and the same TCP or UDP protocol). Such routers may also be configurable to use different port numbers for this proxying service.
# The Internet without local broadcasting{{snd}}if (as often) the firewall or router at the destination does not permit packets received from the Internet to be broadcast to the local network, Wake-on-Internet may still be achieved by sending the magic packet to any specified port of the destination's Internet address, having previously set the firewall or router to forward packets arriving at that port to the local IP address of the computer being woken. The router may require reservation of the local IP address of the computer being woken in order to forward packets to it when it is not live.
