VPN Knowledge
 

Since their seems to a few intelligent people on this forum I thought i'd give this a shot.

Basically I'm wondering if soeone has a router with VPN passthrough on several protocals (IPsec, PPTP, etc.) if that router coudl be used with the N900 to make the N900 appear on that local network?

Reason I ask is becuase I'm having issues getting magic packets to be recieved via the internet (I believe my ISP is blocking them). SO I'd like to make the N900 appear (via VPN) local on the network so that I just broadcast the WoL package locally.

Any help would be much appreciated by myself and also mother earth and I can power down the computer when not needed (and be able to turn it on when needed).

THanks!

VPN passthrough is what they call routers with NAT and software that alows the use of ipsec vpns between clients on the 'inside' network to vpn endpoints on the outside.

WoL is a special form of Ethernet packet. It simply cannot be sent across an IP router. To send one of these, you will need to instruct a machine on that network to send the packet.

Re: VPN Knowledge
 

If you have a router on the local network (Considering a home network), why not access the router (which hooks you up to the internet) and let it send the MagicPacket.

For example the Fritz!Box is able to send WOL calls via a build in GUI.

There are modified firmwares for the vast of routers out there which enable them to to do the same (if not out-of-the-box)

This would be a way around.

Another way around is to access a PC in the local network via VPN, SSH, ${WHATEVER} to send the WoL signal (as jaark already implied)

Well it's a magic packet, coming from a website, or from a script run locally on the n900. (dslreports.com is one website which will send a magic packet via the internet)

The question though is will a router with VPN pass through for several protocols, allow me to set the n900 up on the LAN as a local machine to that LAN?

I was under the impression the router needed to be able to run as a VPN server and not just as a passthrough.

Blubbi: I'm using the DGL-4500, and I'm not sure their is a firmware for it outside of D-links. Would be nice, but d-links firmware is pretty complete, outside of the ability to send a magic packet.

THe other option of ssh'ing to another computer, would mean that this computer would need to be on all the tiem, which kind of defeats the purpose.

Re: VPN Knowledge
 

No, VPN passthrough allows a VPN 'client' to connect to a VPN 'server' (technically both just 'VPN endpoints') on either side of the router. If your router can be configured as a VPN endpoint (the cheaper home user ones generally can't) then you can connect to the network and send data via IP (TCP/UDP etc) as though you were on the local network.

WoL works at a level 'below' IP. Most VPNs work at the IP level and thus cannot transmit your WoL packet. you will need a machine that is actually on that network to generate the packet. A VPN would be a useful technology to connect to such a machine.

Re: VPN Knowledge
 

Well then an alternate firmware is your only hope.

There a different 3rd party OS for routers, just search them.

For example:
http://www.dd-wrt.com/
http://openwrt.org/

or just search this list of OS for your router:

Well I have an old Linksys router that I actuallyt had dd-wrt installed on. Loved it. Just didn't support wired 1000, and didn't have have wireless n.

I should be able to plug it in though, and put the computer on that router, and then just port forward all the traffic to the linksys router.

Re: VPN Knowledge
 

Thats might work.

Re: VPN Knowledge
 

blubbi, being a native of Germany you might be able to answer this but does telekom block udp traffic? (specifially in the range of port 9-9999)

Using their speedport router/NAT I've been unable to pick up a package sent to me via the internet using wireshark. Pretty frutrasting. Of course it's a rather mute point now, since the linksys will probably fix the issue without needing UDP at all (at least remotely).

Re: VPN Knowledge
 

My Internet connection is not provided by T-Online (Telekom) so I can't answer your question. But it could be an issue with either T-Online or the SpeedPort (Never had my hands on one of those)

A workaround would be to use OpenVPN via TCP.

Use any router that supports DD-wrt here is an excerpt from the help page on my router.

Wake-On-LAN:
This page allows you to Wake Up hosts on your local network (i.e. locally connected to your router). You can manually wake up hosts by clicking the Wake Up or you can program an automatic schedule wake up thanks to the WOL daemon.

You would log on to the router from the internet using Https and a strong password. and use the dd-wrt gui to wake the specific box.....

Hope that helps

I am using DD-WRT v24-sp2 (09/24/09) vpn on a Buffalo WRT54G/GL/GS router which is running openvpn server. The router is set up so that I can, with my N810, log in to the router via wlan/lan or connect to my local network via openvpn.

So with such a set-up I can wake up a box on my local network (with WOL) via the router wake on lan settings (without using openvpn) or do it via openvpn.

It took some time to set my system up but it works like a charm.:cool:

Some links that may be of help in setting it up.

Re: VPN Knowledge
 

Thanks guys. I got the router up and running. I was using v23 pre SP1 even. Upgraded it to v24 SP1 as I didn't want to use a not fully stable build.

Got it all up and running, and it SHOULD be working. But when I go in to trigger the WoL/Magic Packet, a lot of times the computer just ignores it. With the computer on, I used wireshark to ensure the packets are going out. They are.

It's really kind of wierd. Sometimes it works, and the computer wakes up, but the majority of the time it ignores the packet.

Anyone have any ideas. (I've tried with only except magic packets, and without checked in windows.)

can you put in another network card/driver to rule out an unreliable network card?
