How many of you have an HA solution, which is open to the internet? (lemmy.world)

I'm running my own HA locally, in my house, but I would like to be able to access it also when I'm not home. So I've put it on my Zerotier One VPN, which works fine. Except for two things:

  1. HA no longer knows when I'm home - it thinks I'm always home;

  2. Other people in my household would also like to have remote access, but it's unrealistic to have them install and use the VPN.

So - can I just open it up, and rely on long, complex passeords? Or is that a complete no-go?

DDNS might help you with that

Yeah, I just made a quick script that queries my public IP every 5 minutes, then changes the a-records via the registrar's API, if it detects a change.

@dislabled
Nowadays there are lots of people without a routable IP V4 address. As providers don’t have enough addressspace for all their customers they use NAT.

Yeah I know, i have turned down 2 potential ISPs already, because they use cgnat. Too bad, because they are cheaper. Just wish ipv6 would really catch on soon.
