If you have a computer on your local network you want to wake from the Internet and you have a TP-Link router (in this case a TL-WDR4300) you are in luck

First, create a “virtual server” (or port forwarding) in which we forward an arbitrary port to port 9 at the IP address of the machine you wish to turn on (Go to Forwarding → Add New):

Add virtual server

If you test as this point, it will work. But at a later point it will not. This is because the MAC address of the machine you wish wake will be flushed from the router’s ARP table.

The way to fix this is a bit illogical but it works. With the machine in questioned turned on, go to IP & MAC binding → ARP List, find the entry you need and click “Load”

Add ARP bind

Now, go to IP & MAC binding → Binding settings and tick of “Bind” for the entry of your machine (also make sure ARP binding is enabled) and then press save.

Create binding

You should now be able to wake your machine from anywhere in the world, using an online service or a client on your smartphone.

Wake on LAN from phone

I am aware of the potential problems of allowing this kind of traffic into my local network but since a malicious person would need to know both the external port and MAC address of the internal machine and is only able to start up my machine, I’m not too worried. If you worry, add a password to your wake on lan configuration.

I går, efter flere måneders test, åbnede QuickDNS dørene for offentligheden.

Hvorfor endnu en DNS-udbyder? Jeg har et ambivalent forhold til GratisDNS. Servicen er god nok (og prisen rigtig :) ), men jeg er ikke altid enig med Peter Larsen; specielt hans involvering i dotdk har gået mig på. Heldigvis ser det ud til at man nu kan vælge udbyder hvor det tekniske er i højsædet.

QuickDNS er en non-profit-tjeneste, der tilbyder DNS-service til vores brugere. Vi gør dette for at skabe en stabil, gratis og økonomisk uafhængig DNS-platform til internetsamfundet med udgangspunkt i danske forhold.

Servicen udbydes af fire dygtige folk (jeg kender de tre af dem) og uden tilhørsforhold til hverken firmaer eller organisationer.

Der mangler stadig småting rundt omkring, men mange af dem er på vej og jeg har selv valgt at flytte mine domæner til QuickDNS. Indtil videre er jeg svært tilfreds med både webinterfacet og name-servicen.

Godt gået!
