I'm trying to set up a site-to-site VPN using RRAS on two 2K8r2 servers since yesterday. The connection is working at this point, but I can't get it to send traffic from one site to the other one.

Set up: the set up is the same on both sites: the server is connected to a router that's connected to a modem. The routers act like a DHCP-server and assign IP addresses from the range subnet.21-subnet-.100. Both servers use a static IP address, subnet.11, and are set up as DMZ.

Configuration: the servers are configured using the wizard to set up a site-to-site connection. This works with a demand-dial interface and a PPTP VPN connection. As mentioned, the VPN connection work properly.

Problem: I can't get the servers to send the traffic for the other site, to be sent through the VPN connection. I added a static route on both server (home, office 1) and I can see the result in the IP routing table (home, office 1). I did this because the route didn't show up automatically. My guess is that this last step isn't right, for example because the routing table states "non demand-dial", which seems not correct.

Home:

  • Subnet: 10.0.1.0/24
  • Router: 10.0.1.1
  • Server: 10.0.1.11 (DMZ)
  • DHCP: 10.0.1.21-10.0.1.100
  • RRAS DHCP: 10.0.1.101-10.0.1.150

Office 1:

  • Subnet: 10.0.2.0/24
  • Router: 10.0.2.1
  • Server: 10.0.2.11 (DMZ)
  • DHCP: 10.0.2.21-10.0.2.100
  • RRAS DHCP: 10.0.2.101-10.0.2.150

I hope someone has an idea to get this route working!

what do you mean by server? Is this the server that works as the vpn server?

Because when you still have a separate internet connection with a router at .1 than that is used as the gateway for ip's not in de same range.

Try setting your default gateway on your client computers to .11

  • The server is the computer that runs 2K8r2. It's a simple setup with just one server on each site. So yes, that servers works as the VPN server. I tried to connect to the other site from the server itself, so the clients don't have a role at this moment. I just set the default gateway to .11 on the server on the outside site, but I lost my RDP connection and can't get connected now ;-) – Jonathan Feb 25 '11 at 21:27
