Most of the VPN services I've found online are for accessing external websites, but that's not the kind of VPN I'm looking for.

I'm looking for a VPN service where two machines from the internet can connect to each other as if they were in a LAN, something like a virtual office.

Does anyone here have any experience with this type of VPN? It'll be for 5 computers max (maybe even fewer).

Any advice is welcome.
