connect two PC's over a windows configured VPN using a Netgear DG834G Modem Router

I have two PC's which have been joined to a domain and have been relocated to another office several miles away. When I try to connect to the Small Business Server 2003 R2 I can only connect one PC over the windows VPN connection. If I also try to connect the other PC the VPN dial up gets to "Varifying username and password" then hangs and comes up with error 721 and will not log onto the Small Business Server.
Does the Netgear DG834G Modem Router used at the same office as the two PC's only support one VPN connection? How can I connect several PC's simultaniously using the windows configured VPN connection?

Do you know which version of DG834G Modem/Router you have?
There are 5 version from V1 to V5 - it may make a difference to the answer.

Have you thought about using a site to site VPN? - the DG834G can handle this!
What is the router at the other end?
I am pretty sure that I have come across the same problem with the same routers and there seems to be a restriction to a single VPN passthrough connection.  I'm digging for confirmation at the moment.
If you create a site to site VPN, this should remove the problem.

Hi Alan
there is another DG834G but an earlier version. Then this connects to the SBS 2003 which has two network cards, one to the external subnet & one internal.

how do I configure the DG834G to connect to each other over a common VPN?

Have a look at the following Netgear articles: - download the reference manual from this link - it describes how to setup the VPN to another DG834G.  Chapter 6 Page 19.
