To expose your services easily and securely look up tailscale it’s completely free and is setup per device, ex download on your moms phone and you can manage that phones access.

Tailscale uses wiregaurd and some weird ass NAT magic to make every device have direct connections to each other creating a “tailnet”

It’s a zero trust architecture so you have to whitelist every device on it. What that means practically is it’s very difficult to compromise and that’s by it’s nature. You don’t have to have a high technical level to be very secure using tailscale.

There is also twingate which I think is similar but I’m not as familiar with twingate

That’s fair but tailscale isn’t a traditional vpn, it makes direct connections between two devices. it was also designed to be extremely easy to setup and it’s free for up to 100 devices.

Again it’s fair if you don’t want to mess with it
