I'm looking for a service that can manage multiple VPN connections. I'm a developer and my goal is to connect to a specific VPN whenever I need to code and debug on a specific target.
Looking on the Internet I found a lot of "VPN" services but they are for surfing privately... instead I want to create VPNs with my own machines running in remote places.
Question 1: what are the correct English search terms to find this kind of VPN services avoiding the ones related to surfing privately?
Question 2: I'm able (with some effort) to create a VPN between to machines using OpenVPN but it's not very straighforward... and because I'm going to manage dozen of machines it would be a nightmare. Is there a software that make this task easier? Like Zoho Assist for remote desktop where you can easily connect to your machines without dealing with IP/NAT and so on.
