Connecting to my home network

I need to be able to connect to my home / business network from anywhere.
I need to pick a device that that work with my existing router device that will allow me to VPN into my network.

what device from the range is recommended - starting at budget level and working up the range.

I have not need for any other features other than remote connectivity

thoughts and advise please

First need to understand what protocol is your home router using? Openvpn or wireguard?

GL.iNet routers works with Openvpn and wireguard. If you have openvpn, you can geneate ovpn files and upload to the router.

To do that, you can choose AR750S or MT1300.
