I would like to buy a mini computer that I will keep running 24x7 to do a few things:
1) It will run a small software program that I use for my business.
2) I also would like to use the same computer for openHAB to power the automation devices for my house.
3) I want to use it as a NAS to store a few files
I can get all of that set up but the challenge is I would like to be able to access this computer remotely when I need to. I don't really like the idea of opening any of the ports on my router's firewall so a direct remote desktop connection won't work. I don't have any experience with VPNs but my understanding is this could be a way to get around that. I could install openVPN on the computer and keep it connected to the VPN server. Then I can connect the computer/tablet that I am connecting from remotely to the same VPN server and login via remote desktop that way.
However, I've read that when you connect to a VPN it will change my IP address on my local network which will likely cause problems for openHAB and the NAS or any other connection on the LAN. Is this true and if so what can I do about it? Is there another solution? Thanks
