WOL over Internet / WOW

Ozymandias · 9 Feb 2010 at 23:47

I have a WHS acting as a VPN behind a DG834GT. The WHS is set to sleep using LightsOut. I'm looking to wake it from the Internet when away from home and then VPN in.

Current I have enabled remote admin of the DG834GT with a strong password, allowing me to log into the router and use the WOL facility in the dgTeam firmware to wake up the WHS, log out of the router and VPN into the WHS. However I'm a bit worried over exposing the remote admin feature to the INternet.

As the DG834GT doesn't support WOL over Internet / WOW I'm thinking of maybe a new router that does. However issues seem to existing in having the WOW feature exposed on a router as well.

Any thougts on the best solution? - other than leaving the WHS up all the time

Hi,

I have been trying to wake up a PC on my home network remotely so I can then gain remote access.

I tried port forwarding on the router and using a WOl utility remotely to send the wake up packet but this didn't work, however it did work when I used the WOL utilty when I was at home on the same network.

Being a bit stumped in the end I used the Tomato Firmware on my Linksys router which enables you to log in to the router and then use the router to WOL using the mac address of the PC you want woken up.

It worked a treat and had no problems with this whilst I was away in Singapore and later New Zealand.

Obviously there is a risk of having your router accessible on the net, but you can configure which port to login on and have a decent strong password also.

There is the risk of your IP changing on the router but being on Blueyonder(now Virginmedia) I have had the same IP for 11 months now !

I have been having trouble getting this to work on DD-WRT whilst logged into the web interface or SSH.
Although I have a feeling this maybe do to the wireless bridge (only one mac for everything attached to it as seen from router), and/or a problem with the computer not leaving the NIC active on shutdown (Linux [ubuntu] Server).

I think the trick on the Linksys is to set up a static arp linking mac to ip and use port forwarding.

On the Netgear there seems to be no way of setting up a static arc and so after 5 minutes of the target machine being turned off the arp cache is cleared and so no link exists between the ip of the port foward and the mac of the machine. Beyond this Netgear seems to actively block wow packets across the wan/lan interface.

The correct way is to set up a broadcast of the wow i.e. xxx.xxx.xxx.255 but my Netgear does not allow this.
