I've attached a diagram on here to better describe my problem.
We have a warehouse at Site A. They have a VPN directly to our head office at Site B. At both of these sites we have a Sonicwall fireall (one is a TZ 210 and another an NSA 3500).
From Site B, have a VPn connection to our hosting provider. So we use a LAN IP to connect to a remote desktop services session using a 10.45.190.0/24 address.
However, we want people at site A to be able to remote desktop on to the 10.45.190.0/24 network by routing it via Site B. How can I do it so that somebody at a PC at Site A is able to remote desktop onto the 10.45.190.0 network in that way? (i.e. routing it via Site B)
2. At Site B - Create an Address Group that includes an object for Site A's network and the LAN of Site B. Make that the Local network for the VPN to External Company.
3. At External Company - Have them add the network for Site A to their Destination Networks definition for the VPN.
All objects specified would be members of the VPN Zone.
