I have a question as to whether the following scenario is possible to configured.
I have a main site, that needs to create a VPN tunnel to remote client sites, assumably via a LAN-2-LAN connection. I need to be able to access all routable subnets on each remote client subnet.
The problem is that the remote sites themselves may have multiple subnets connected to their VPN concentrator as a function of their overall corporate star topology VPN environment. These subnet schemes may overlap from client to client. So while I've seen examples of how to overcome this problem if the immediate remote sites overalap, I haven't seen anything that talks about how to access the additional remote network subnets.
Is this possible?
SITEA <--> CLIENTA (10.0.1.x) <--> CLIENTA-SUBITE (10.0.2.x)
and at the same time
SITEA <--> CLIENTB(10.0.1.x) <--> CLIENTB-SUBSITE (10.0.2.x)
I guess I need to say that x number of subnets on my side, map up 1-to-1 on the x number of subnets on the remote side.
Any thoughts on if this is possible, and how best to address?
