Best option for setting up OpenVPN between 2 locations?

[TexasUnraid]

Not really the place to ask this but not sure of a better place.

 

Long story short, I need to setup an openvpn connection between 2 locations so that I can share the lan connection between the locations.

 

I need to manage some systems in home 2 from home 1 primarily, so SSH/VNC/IPMI/HTTP access to the LAN in home 2. Being able to send files across via smb would be a big bonus but I could figure out alternate options if needed.

 

Home 1 has PFsense as a router, also my unraid server that runs almost 24/7 (been crashing randomly lately).

 

The hardware in home 2 is an Ausu AC68U with merlin.

 

Not sure what the best method would be, have an openvpn sever on pfsense and the client on AC68U with a bridged connection? What happens if it can't setup that tunnel? I need the internet on both ends to be unaffected regardless.

 

Setup a VM/docker on unraid that connects to home 2 and then manage things through that?

 

I am looking for noob friendly guides to watch/read to learn how to do this. Never messed with openvpn outside of PIA.

 

Anyone know where to look or the keywords to search?
