Nokia MW1122 Wake-On-LAN over internet settings

[cj]

Is this possible? When I go overseas, I would like to be able to wake
my computer up remotely.

I have tried routing incoming UDP traffic on my MW1122 to
192.168.1.255 (which should be a broadcast to the entire 192.168.1.x
network), but to no avail. I have a feeling that the MW1122 is
ignoring my broadcast request.

I know WOL works on my computer, since I can actually wake it up from
within the network, and I have a WOL magic packet sniffer that tells
me I am picking up the packet from within the network. It is when I
try to do this from over the internet it fails.

Are there any specific settings on the MW1122 I have to change to
enable this? Any help is much appreciated!

regards,
john c.

The WOL app i am using is from depicus.com. And i am also using their
WOL packet sniffer to test on the machine i want woken up. Port 7 is
also the UDP port I am using (though im sure this doesn't matter).

I used a subnet mask of 255.255.255.0 though... perhaps i should try
255 at the end as well.

sigh, im not going to be changing my MW1122 to anything else anytime
soon so hopefully it is just a setting that ive missed out on it.

regards,
john

Yes its possible. Possibly not with the M1122, but it should be.
I'm successfully doing Wake on Lan over the Internet using an Alcatel
Speedtouch 510v4.

I'm doing the same thing - except that I'm only forwarding a specific UDP
port, and using a Wake on Lan app that lets you specify the port. I'm
forwarding port 7 UDP to 192.168.1.255. Most wake on Lan apps don't allow
you to specify the port.

Most likely its the Wake on Lan app you're using, is not suitable for
sending the request over the internet. I had to try 4 different Wake on Lan
apps until I found one that worked over the Internet.
The one I use is called "Wake on Lan - Magic Packet" and is from
http://www.depicus.com and as fate would have it, their site is down
today...GRR.... I can send you a copy though if you like, its very small.
Mac Address (mac address of the machine you're trying to wake up, naturally)
Internet Address (outside ip address of your Jetstream connection)
Subnet Mask (when doing WOL over the internet it needs to be 255.255.255.255)
Send Options (A choice between Internet and Local Subnet - Internet)
Remote Port number (I use port 7, arbitarily)
Most Wake on Lan apps assume you're on the same lan and wont let you
specify a single host subnet mask, and also wont format the request as a
UDP packet to a specific port. (Since a Wake on Lan packet over a lan can
be ANY kind of ethernet frame that includes the magic byte string)

Hi John,

I have done a fair bit of playing around with WOL. As far as I know, a WOL
magic packet is sent via the network as a layer 2 packet, meaning that it
references the MAC address of the NIC as opposed to the IP address. Since
the Internet works on layer 3 (IP addresses), standard WOL will never work
over the Internet, unless you have some sort of VPN or other tunnel which
will transport layer 2 traffic to your home LAN.

There is one exception to this, and that is 'Wake On Ping'. WOP sets up the
NIC to listen for layer 3 pings to it's assigned IP address. I have had
this working within a LAN, but I've never attempted to get it working over
the Internet (I'm not even sure if it's technically possible).

I'm actually about to look into this for a client of mine so if I find any
magic (excuse the pun) cures I'll let you know :)

Sam.

I already replied to John offlist, but just for the record, thats wrong -
it is possible to use Standard Wake on Lan over the internet with a little
bit of cunning - I know, because I use it all the time to wake up my home
PC remotely.

A wake on lan packet can be ANY kind of packet provided that it has the
magic sequence in it which includes the MAC address of the network card.
All you need is some way of getting the Jetstream router to emit such a
packet on the lan when the PC is off (and thus isn't responding to ARP
requests) in response to some outside source.

Port forwarding an unused UDP port to the broadcast address of the LAN as
John is doing is the easiest way, and as long as your Wake on Lan sending
app can send the right kind of packet it will work.

From John's reply it sounds to me like he is doing everything right (even

using the same Wake On Lan app that I do) but I suspect that the M1122
will not port forward to a broadcast address.

My Speedtouch 510v4 will happily port forward to the broadcast address,
and therefore it works. Another way to do it (for a single LAN machine)
would be to add a static arp entry on the router - again the Speedtouch
can do that, but I don't know if the M1122 CLI can support static arp
entries.

If the M1122 can indeed support static ARP entries, that would be the next
thing to try, set up a static arp entry for an unused ip address on the
same subnet and port forward to that instead of the broadcast address.

Simon

So this app from depicus.com does the embedding of the magic sequence in an
L3 packet? What is the web site for this? www.depicus.com doesn't seem to
work for me!

Yes, in a UDP packet.

Yes, it seems to be down. I downloaded it some months ago... hopefully its
only temporary, as it seemed to be the best one of the bunch when I was
trying to find one that would work over the internet...maybe there is a
mirror site somewhere.

hmmm, I will try what u have suggested, however I am no MW1122 admin,
and all I have managed to do is to pinhole so that certain apps and
games will work over the internet. All the other settings (especially
via CLI) might as well be written in some other language.

from what i have tried so far, people tell me that it *should* work,
however, the MW1122 seems to be blocking all broadcast traffic from
outside. sigh... anyone out there know how to properly configure the
M(W)1122??
