I travel quite a lot and I am getting really tired of applications, websites and businesses causing problems because I'm not at home.

What I'm hoping to do is setup a self-hosted VPN or proxy in my home country (not interested in my own hardware, computers would be turned off when away from home), I am happy with a single IP address and don't care about it being tracked, but I need it to be secure. I just want every bit of traffic from my device(s) to appear to come from my home country without any possibility of others knowing I am elsewhere *or* that I am using a VPN.

Is this possible? I've been looking into Wireguard and obfuscation. I was planning to install that on a dedicated host. Is this the right direction? Appreciate any help!
