RRAS demand dial between two sites

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance



I have two remote sites, both with ADSL connections.

Each site hosts a domain controller for the domain.
SiteA has subnet 192.168.0.0/24
SiteB has subnet 192.168.1.0/24
Each network has a DSL router with the address 192.168.x.1
The IP address of the servers is 192.168.x.2

e.g.

SiteA Server
192.168.0.2
|
SiteA Router
192.168.0.1
|
Internet
|
SiteB Router
192.168.1.1
|
SiteB Server
192.168.1.2

Port forwarding is enabled on each router to allow PPTP, and VPN
connections can be successfully established to either site.

What I'm trying to do is to enable seamless routing between the two
networks for all clients, without having to purchase any more
hardware.

I'd like to configure this using RRAS, but I'm not 100% sure how to do
it. I've attempted to do this using a demand dial interface to form a
VPN connection to the other site (and the same in the opposite
direction), but having two VPN connections (one from SiteA to SiteB
and another from SiteB to SiteA) doesn't seem right. Should I be doing
this with a single VPN connection, that can be used in both
directions? If so, how can I accomplish this?

For info, both servers are domain controllers for the same domain
(SiteA is SBS2003, SiteB is Server 2003 Std), each server is placed in
separate site, and the DCs can replicate, but this isn't very reliable
due to the link problems I'm seeing.

Kind regards,
Bryan
