SuperHub - Anyone Tried WOL - WAN to PC?

javadudd · 10-02-2011, 10:18

Just wondering if anyone has tried to remotely send a Magic Packet to wake a PC?

I know my current WRT320N doesn't support it unless I use CFW but getting the SuperHub installed tomorrow.

It won't work.

or know it isn't supported?

* Require hardware support of Wake-On-LAN on destination computer

Basically the WoL packet can't be passed from network to network (ie over the internet).

Sending a WOL packet over the internet will not work because the protocol does not function over the internet.

Sending a WOL packet from the Superhub will not work because it does not have the functionality to do so.

Your best bet would be to connect your WRT320N to the superhub, set it up with custom firmware, and use that via a port forward.

Sorry I should proboably correct my Terminology to WOL and WOW

Thanks to both of you for your replies although I might be misunderstanding how WOL/WOW works but I thought it would involve some sort of port forwarding rule to say forward this Packet to Port 9 either Static IP or MAC address?

qasdfdsaq are you also saying that this would not work LAN side i.e. True WOL not WOW as I should have said.

The wake-on-lan "packet" is not a packet but an ethernet frame. As an ethernet frame it can only be carried over a direct ethernet link, it cannot be forwarded over the internet. The internet has no concept of MAC addresses or ethernet.

You will need something on your LAN to directly generate a WOL packet from within your LAN.

The WRT320N does not by default support WOW but the DD-WRT custom firmware does.

Do you know how this is achieved?

Obviously capable but in one case enabled and the other it's not.

I have Android Phone App which allows me to do this currently so I take it will still work with Superhub?

I don't know how dd-wrt does WOW, as I have never seen or used WOW.

I do know that dd-wrt can perform normal WOL via the web interface, and this is what I use.

Not a chance. Most home routers won't, more as a security feature so spam packets aren't sent to the LAN broadcast address (x.x.x.255). If you really want this you need a seperate cable modem and router, with the router running DD-WRT or some other high-quality third-party firmware. Then you can log into the web GUI remotely (or the command line, if you want) and use DD-WRT to send a magic packet to the target MAC address internally. I do this and it's faultless: I can then remotely VNC control my PC, with the connection using 128-bit AES. Handy in cases where you're on a limited internet service (i.e. certain sites are blocked) and want to tunnel through to your home connection instead, or perhaps to retrieve a file.

Thanks for that.

Hopefully when the update comes out I'll be able to do just that i.e. turn off the router part of the SH.

You need to setup a Dynamic DNS service and input that information in your router:
http://www.dyndns.com/services/dns/dyndns/

Once you have an account, input that information into your router's admin page under "Setup" and then "DDNS" (enable DynDNS.org)
(usually 192.168.1.1)
(Note: I have a WRT320N as well and it is 192.168.1.1 for me but you may have changed it)

And then you need to change the subnet to something NOT 255.255.255.0 and setup up WoL port forwarding in the "Application & Gaming" tab under "Single Port Forwarding." I have it set up for both UDP/TCP on ports 7 & 9 to the internal IP address of the pc I want to enable WoL for. Obviously you have to have WoL enabled for that pc.

(Note: Everything I've researched says WoW doesn't work for the WRT320N)

There's an even easier way to WOL that involves DynDNS (or memorising your current IP at least) and setting up some scripts within a DD-WRT flashed router. Then sites like wakeonlan.me actually do WOW (Wake On LAN via WAN) correctly. For more information, have a look here.

I use this method and it's faster than logging into the web GUI or telnetting the router and inputting command line stuff, and has allowed me to create a simple batch script which WOW's one of my home computers, allows time for it to boot or wake from sleep then connects to the VNC server.

The only reason I need WoL is in conjunction with LogMeIn. I have one machine that runs 24x7 anyway but my laptop downstairs gets turned off and I sometimes need to access that remotely. Pre-Superhub this was no problem without doing anything special (20Mbps cable modem to WNR2000 and later to a Buffalo running Tomato firmware both worked).

To get WoL via LogMeIn working with the hub I had to use a fixed IP on the laptop and forward port 9 UDP to it. That works. The Superhub can't just send magic packets around all devices on the network as it doesn't support n.n.n.255 as a valid IP for forwarding.

This is simply not true. I’ve been using WOL over Internet for years. The only problem with this is that most cheaper routers don’t allow port forwarding to broadcast address. Check this tutorial http://www.mysysadmintips.com/index.php/clients/84 There even is web based WOL packet sender which works absolutely fine over Internet.
