Colin,
Let me explain my scenario,
I want my remote branch users (5-10) to connect to the corporate office when the WAN connectivity fails, these users are all connected to a switch with a different network prefix than that of the corporate DC network. If i have to acheive this i am considering to deploy a RAP-3WN connected to the same switch where the users and the branch router is connected. The use case would be as under;
1) No VPN clients on the user machines, they have to connect seamlessly to the corporate network with the existing branch network prefix.(since their applications are mapped with their ips).
2) In case of wan link/router failure, the traffic to the corporate network should take the cellular route through the RAP.
3) In case of failure of the wired network port/cable of the user, the user should be able to latch on to the RAP via wireless and get access to the corporate network.
with the above conditions is it possible to configure the RAP-3WN for site-site VPN connectivity( I have gone through the document link sent by you and have seen there is an option for site-site vpn connectivity on the controller)
Please do advice on how this can be acheived.
Regards,
Mahesh
