I'm trying to figure out the most efficient way to securely establish a VPN tunnel that will connect multiple customers to a customer dedicated NAS located at my office (1 per customer) . The purpose is secure off site data backups.
I'd also like access to the various customer networks for remote maintenance from my office PC.
Based on my research, I'll have to install a VPN router at the customer's site and configure the VPN connection. At my office end is where I'm questioning my logic.
To isolate the customer networks from each other, is a dedicated router at my office for each customer or VLAN the most appropriate. The NAS I plan to use has VPN capabilities, so I'm thinking that a VLAN might be the most cost efficient.
The idea is that each NAS would be always connected and available on the customer's network.
The router I plan to install at the customer's site is the RV320k.
What am I not considering or over simplifying?
