I currently have a server running Unraid as the OS, which has some WireGuard integration built in. Which I've enabled and been using to remotely access services hosted on that server. But as I've expanded to include things like Octopi running on a Pi3 and NextcloudPi running on a Pi4 (along with AdGuardHome), I'm trying to determine the best way to VPN to my home network with the goal of reaching services I'm hosting, and do it safely of course.
I have a Netgear Nighthawk that has some VPN functionality built in that uses a OpenVPN account. Is that ok or would it be advisable to come in a different way?
As others have said, I'd play with routing/IP forwarding such that being VPN'd to one machine gives you access to everything --- basically I would set it up as a "road warrior" VPN (but possibly split tunnel on the client [yes I know, WireGuard doesn't have servers or clients but you know what I mean]).
Alternately, I think you could do some reverse proxy magic such that everything goes through the WireGuard box --- a.lan goes to service A, b.lan to service B, etc., but if you have non-http services this may be a little more cumbersome.
