Please help: A beginner VPN two broadband connections together

Dear all,

Myself and a friend both have broadband internet connections, one being 512k and the other being 1mb. We both have similar setups at home using a DSL modem/router to plug the broadband into the wall then having a win2k ad server to act as active directory, DHCP, etc etc for the rest of the clients on the network
we would love to setup a VPN connection between our 2 sites but both being pretty inexperienced with VPNs (having never used them before) we are having issues making it work.
We have RRAS installed on the server and I would really really apprieciate someone to help me try to get this working.
I have heard so many different idea floating about like "oh you need 2 NIC's installed" or "no you don't need 2 NICs that just makes it harder" and quite frankly I am confused.
The whole idea of us getting this working is to enhance our knowledge and get something funky like this to work, plus its just fun :)

My friend has a static IP from his ISP and I have a dynamic IP mapped to a DNS name using 3rd party software (don't see this being a problem, but then if I knew all about this then I woudn't be here now!)

So basically what i'm saying is that i'm totally dumb when it comes to this and will take any help and advice I can get.

Many many thanks for any help

P.S. the two routers that we're using are a Thomson Speedtouch 510 and Netgear DM602

If you want to save yourself a whole lot of asparin (for those headaches), replace the two routers with VPN capable routers, like the Linksys BEFVP41, RV0x, BEFSX41, WRV54G, and in two minutes you can have a LAN-LAN VPN tunnel between the two routers and have full access to each other's networks. Only one word of caution - make sure the two networks have different IP subnets, or they will never be able to talk to each other..

In order to familiarize yourself with what you need to do, you should read 'Virtual Private Networks for Windows 2000' (

After that, you can take a look at 'Planning and Installing a Windows 2000 Remote Access VPN Server' ( for instructions on how to set up the VPN server.  Windows XP and Windows 2000 come with a built in VPN client that you can use to connect to the VPN server.  If you are using a different Windows OS, you can download the client from links in the first article above.

Lastly, you can read about how to make a secure VPN connection to the VPN server here: 'How to Configure a L2TP/IPSec Connection Using Pre-shared Key Authentication' (;EN-US;Q240262&ID=KB;EN-US;Q240262&LN=EN-US&rnk=1&SD=gn&FR=1&qry=Q240262&src=DHCS_MSPSS_gn_SRCH&SPR=CHS&).

BTW - this would be much easier using two VPN routers, but then you'd miss out on the fun :)

Actually, skip that - lrmoore said it better in the interim  :)

Thanks for the information so far guys, the issue with getting two VPN capable routers is a money factor i.e. I have absolutly none of it left (another long story)

I think we have everything in place to be configured. We installed RRAS on one of the servers and started the setup wizard when it asks you to specify the connection that the server uses (<No internet connection> or Local Area Connection)

If I specify Local Area Connection then it gives me a msg box stating that 'You have choses the last available connection as the internet connection. A VPN server requires that one connection be used as the private connection'

Is this the bit where I need to install 2 NIC's?

Sorry for being dumb when it comes to this but you gotta learn somewhere right!!?!
