Remote controlling home PC using TeamViewer and Wake on WAN.

I spent some time a while ago wondering whether I should enable remote controlling on my PC and I reached the conclusion that it is worth it. Nowadays I can access my PC from anywhere using my tablet or even my phone.

In order to achieve the above I am using TeamViewer (which is free for personal use) and Wol Wake on Lan Wan by Brobble from Google Play.

The steps that I have followed are:

1. Set up account, install and configure TeamViewer with auto-login
2. Set up the router for port forwarding
3. Download the application from Google Play
4. Set up a profile for the app that would send the wake up packet to my route

No. 1 is pretty easy and I will not detail it. It is a straight forward process.

My router is from O2 and the in order to set it up for port forwarding the following steps are necessary:

• Login to the router with an administrative account
• Find Toolbox/ Game and application sharing
• Chose Create a New Game or Application
• Name it WOL and chose Manual Entry of Port Maps followed by Next
• Protocol - chose UDP
• Port range 9 - 9
• Translate to 9
• Trigger protocol - Any
• Click Add and Apply
• Chose the task Assign a game or application to a local network device
• Chose as Game or Application WOL
• As Device chose the laptop that you want to wake up
• Take a note of the MAC address of the laptop

In order to complete number you will need to setup the profile as follows{

• Name: whatever you wish, not important
• MAC: the MAC address of the laptop
• IP or Domain: your external IP or domain if you are using a forwarding service as DynDNS (you can find your external IP using a service as ipchicken.com)
• Port: 9
• Send Multiple: ticked
• Packet count: 5
• Interval: 1
• Tap Save

That's it. Oh yes, one more important thing, the laptop needs to be connected through a wire and not by Wireless to the router. 

UPDATE: you will need to make some changes on your O2 router in order to allow you to add a static ARP otherwise when the router re-starts or after a certain time of inactivity the above method will not work. I will not add this details here, you can use Google to find the way to do that.
