Here is my network config. I have been going crazy trying to find the solution...

 

I have a SBS 2003 R2 with 2 Nics. One is connected to the Cisco Router, One is connected to the Network Switch. My inside address is 192.168.0.1, outside (to the Cisco Router) is 10.10.10.2 (Router is 10.10.10.1). Cisco Router is connected to the Interent, and has DMVPN that is working between with a Tunnel up between other Cisco Routers at remote locations.

 

I can ping and access desktops at remote locations from the 192.168.0.0 subnet, but I cannot access file shares on the 192.168.0.0 subnet from remote locations. I can RDP to the 10.10.10.2 side of the SBS with only the Tunnel up, but cannot RDP to the 192.168.0.1 NIC unless I first create a VPN to the Server.

 

I am thinking what I need to do is to open a port on the 10.10.10.2 NIC in RRAS, but perhaps I need to create a static route, I am not sure. Any suggestions are greatly appreciated....

From the way that you can ping the 10.10.10.2 interface from outside a remote network but not the 192.168.0.1 interface, my assumption is that it is with the firewall. I have the firewall in RRAS disabled, but still with no success.

 

I can even remote desktop to a different 192.168.0.0 network machine without a VPN, with only the tunnel in place between the Cisco routers.

 

I am assuming that there is a port in the SBS that need to be opened to allow communication between the 10.10.10.0 side and the 192.168.0.0 side. It is what seems reasonable.

 

I have tried allowing ports 135, 138, & 139 by creating rules on the 10.10.10.2 interface in RRAS, but still no reply from the 192.168.0.1 interface.

 

Thanks again for any help...

Hi Jim,

Did you figure this out yet?

Hi Iain,

 

You will never be able to achieve that if you are using 2 nics in the SBS server, as the VPN tunnel is terminating at the external side of the network.
