VPN Demand Dial Router to Router

I am trying to set up a Router to Router VPN. The main site is running
Microsoft Small Business Server 2003 Standard.

We have a evaluation of Windows Server 2003 in the other site. I have
successfully managed to set up the Demand Dial connection with this.
However, we can not currently afford to purchase this software, and so need
a alternative solution.

I have install FreeBSD on another machine, this will successfully make a VPN
connection as a mobile user. If I try and use the Demand Dial username and
password the connection is unsuccessful.

Am I correct, that when a demand dial connection is made, both servers log
on to each other. If this is the case would installing a VPN server on my
FreeBSD machine result in my demand dial connection being successful.

Thanks,

Martin Mitchell

I doubt it. Router to router connections work quite differently from
client-server connections. With a client-server connection, the client
usually sets up a default route to the server, but the server only sets up a
host route back to the client. By using demand-dial interfaces, RRAS allows
you to set up routing between subnets across the link.

It is possible to set up a limited version with only one RRAS server (at
the main office) and using something like XP at the branch. If the branch
machine calls the server using the demand-dial interface as its username, it
will connect to the dd interface and set up the route back to the "calling"
router's subnet. But you would have to always call from the branch, and you
would have to rely on default routing on manual config of routes to get the
routing right at the branch end. Only RRAS lets you create demand-dial
interfaces and link the routes to those interfaces, so that the routing is
automatically set up when the connection is made.

I have been successful in getting this to work. I used the package mpd on
the FreeBSD machine.
