Hi All,

Hope you can help out with this, I'll begin by explaining the situation.

My Mom lives in Spain and wants access to the UK based streaming services, a while back she got setup on boxpn VPN service so she spoof her IP as a UK one and view content on her laptop. What I wanted to do for her was take it one step further and make it so that all devices on the network automatically use boxpn, this will also allow her to use an XBOX 360 which has the best range of services available (Netflix, Lovefilm, iPlayer etc.)

So I checked out her current ADSL router which was a Netgear DG834PN and found that it had no options for passing all traffic on the network through boxpn. A little googling discovered that DDWRT supported VPN Client mode and seems to be able to do the trick.

So as the Netgear could be set to a Modem only mode thus removing all routing functions I thought if we pick up a DDWRT supported router like the TP-Link WR740N we could plug the Netgear into it and share the connection utilising DDWRT to push it through the VPN first, a simple task if I was dealing with a normal cable modem, not so much on an ADSL modem it seems. I am unable to get the TPLINK to pick up the connection from the Netgear.

I think the problem lies in the connection method. On the Netgear router for it to connect (when not just in Modem mode) it doesn't require a username and password which then assigns IP address etc. via DHCP. Instead you enter no login details but select a method called "Use IP Over ATM (IPoA)" which then requires you to manually enter your static IP information along with gateway and DNS servers but as I mentioned with no authentication.

I can only assume they operate some kind of static IP system rather than dynamic and assign that IP to a specific phone number so it can only be used at one house...or something along those lines.

The problem is with DDWRT there is no such option. I have tried both PPPoE which simply requires login information and left it blank, and also tried just static IP configuration entering all of the same details as I would in the IPoA section on Netgear but without luck.

As a side note the Netgear also has an option for static IP rather than IPoA and if I use that instead it also doesn't work, so IPoA seems to be the key factor.

The question is, how do I get this to work in DDWRT?

Any help (including alternative router configuration options that I haven't considered to achieve the VPN goal) is greatly appreciated!

Regards

Russ
 
Have you considered leaving the Netgear configured as a router and just connecting the TP-Link behind it? You'd be double NAting, but that isn't the end of the world.
 
Configure the Netgear so it makes the connection to the ISP as normal.

Connect the TP-Link's WAN port to a LAN port on the Netgear and configure it so that it picks up an IP using DHCP.

You'd need them to use different subnets for their LANs, but apart from that any machine connected to the LAN side of the TP-Link should be able to connect to the Internet more-or-less as normal.

The Netgear should allow VPN pass through, so configuring the VPN shouldn't cause too much of a problem.
 
Thanks for that.

Got it set up as follows now:

Netgear configured as router sharing the internet connection
TP-Link connected using ethernet from port on netgear to WAN port on TP-Link

Netgear on 192.168.0.*
TP-Link on 192.168.1.*

I now have a working internet connection if a connect to the TP-Link so I'm one step closer at least!

Now I'm struggling with the VPN portion of it.

On the TP-Link DDWRT control panel I am in Services > VPN and have it set as follows:

PPTP Client Enabled
VPN server details entered
Remote subnet & mask blank
MPPE Encryption blank
MTU&MRU 1436
NAT enabled
VPN Username & Password correctly entered

All settings applied, saved and router rebooted.

Alas it doesn't seem to be using them, I still have my internet connection but still showing as the Spanish IP
