So here is what I would like to do, but I feel like I'm missing something
2 Locations (A,B) connected via VPN Tunnel
Outside clients should not know that location B exists but just connect to all resources as if local to location A, should a resource be located at B than the traffic should be routed via A - VPN -> B
The clients don't have to know about the VPN right? Why should they? The clients can access everything if behind VPN or local at A?
What I feel like I'm missing is the following: How do I have to setup the routes at A so the routing works? Because the traffic should be routed through the VPN if necessary but not always of course, and since the IPs of the VPN and the local Network should be in the same IP subnet I don't get my head around the routes in that case.
Thanks, I don't really know what to look for, so any pointers are helpful
Extending on the Scenario, which this might be useful and is kind of what I want to do: Relocation of a Server to a 2. Site temporarily without having to update any hardcoded IPs or anything like that. The Server or maybe Servers are supposed to keep their IP under which they are reachable, just now they are reachable via VPN Tunnel to the 2. Site but Clients don't have to know that.
I Guess that means a Roadwarrior setup for any Servers relocated.
