I need guidance on how to implement a "hardware VPN" between two customer offices--or at least I "think" that is what I need, but I know almost nothing about all this which I why I need guidance. Here is the situation I'm dealing with:
At this small customer Office 1 and Office 2 each have one Win10 PC on a garden-variety router from their area ISP Centurylink. Office 1 needs to be able to map a drive letter to the share on Office 2 PC and transfer data--just as though both computers were in the same building on a LAN. To do this in the past I've used Radmin set up as a software VPN, which has worked far better than LogMeIn Hamachi in the past, but it is still not reliable.
Meanwhile I was at a customer site with a similar situation and they had a VPN set up using a Sonicwall device at both offices. I asked a few questions about the setup and was told that the equipment is pricey and requires an annual subscription, but that it does provide a reliable connection between offices.
And then I see new high-end routers being advertised as the best for a VPN, but I don't know what all they provide.
So to help me with my lack of knowledge, I have these initial questions:
1) What direction should I go in for this small two-office customer that will give them reliable drive mapping and data transfer--at a reasonable cost?
2) Would I continue using their Centurylink routers, or would I be replacing their routers with different hardware?
3) I get the impression that setting this up correctly is going to be quite complex. Having never done this before, where can I go to get the knowledge I need to do this right? It is OK if there is a cost to getting tech support to get me going.
