ddns-updater VS tailscale

Setup https://github.com/qdm12/ddns-updater to keep you IP address updated for your Google DNS record. This is only need for inbound access while you are remote so that your DNS record is updated if you IP address changes.

Do you mean something like ddns-updater?

This assumes you have your DynDNS mechanism set up by any means other than the Fritz!Box internals (for example, I use this docker image, in combination with my cloudflare managed domain to achieve DDNS behavior). This means that the Fritz!Box needs to be reachable with the domain you intend to use for your VPN connection. For example, I use vpn...

SOLVED: Thanks to some of the suggestions here I realized the WAN IP wasn't actually changing. The DDNS updater I use: https://github.com/qdm12/ddns-updater uses a bunch of different sources, both http and DNS to determine the current public IP. At lease one of the http sources was no longer working and I have no idea how the DNS sources are supposed to know what my current IP is, that doesn't make sense to me.

I use ddns-updater.

Take a look at qdm12/ddns-updater

Use https://github.com/qdm12/ddns-updater. You can buy a standard domain, and this will keep it pointed at your IP.

if youre public IP isnt static, you will need a dns-updater too.

Use a dynamic DNS service like noip.com. You either use one of their domains like myusername.someDDNScompany.com or you use your own domain. Then you run software like ddns_updater on a raspberry pi or a docker container on your NAS that periodically checks and updates the DNS record with your current home IP.

Tailscale

I'm using the GitHub version of tailscaled on one of my Macs as a background daemon launched at boot. To upgrade to the latest version, try the following:

Tailscale is a VPN service that makes the devices and applications you own accessible anywhere in the world, securely and effortlessly. It enables encrypted point-to-point connections using the open source WireGuard® protocol, which means only devices on your private network can communicate with each other.

Might be possible to do using a VPN as long as you can get broadcast/multicast packets forwarded.

Tailscale unfortunately doesn't support it...yet?

Tailscale - Make depaware output patch compatible

Tailscale is another way of doing it. I'm using it to access my Pi's Samba shares from my phone but it works from Windows as well.
