Germany, dyndns and port forwarding (lemmy.world)

Hello,

I have a Nextcloud server installed at home that works well on my LAN network, but when I try to make the server accessible via a DynDNS service, I cannot connect to it. The request doesn't even reach my server. My question is whether the router immediately blocks the request, because when I set the router to be accessible (it has separately that option), I can connect without any issues over dyndns url. Could my ISP (O2) be blocking it? I can confirm that it's not a firewall issue, and it's also not because I'm connected to the same WiFi as the server. It's not a port forwarding issue either, as I've gone through all possible options. My router is a Fritzbox 6660, and there are no logs indicating that a request has even come through.

My second question is whether this is even allowed in Germany? Also, I've noticed that my ISP rarely changes my IP address; in fact, I haven't seen it change at all in the past few months, which is strange because in my home country, it changed every 24 hours.

Edit: First, thank you all for your help. I will try your suggestions over the course of this week or month (due to time-related issues :) and will report back with the results. Since I am clearly a noob when it comes to self-hosting and I plan to have only a Nextcloud server for personal use, what is the best way to secure the system in these situations and allow only certain devices to access it over the external network? (if I ever manage to access it at all)

Most likely you are under CGNAT, so your best bet is Tailscale, Wireguard, CloudFlare Tunnel or Zero Tier. Pick your poison.

Wireguard will only work if the cellular or ISP at, say the workplace, have an IPv6 adress or IPv4-to-6 translation

Usually German ISPs are giving you IPv6.

This so much of a lie.
Only the usual suspects (new fiber ISPs, Vodafone/KabelBW and O₂) do and usually on the coax and fiber contracts.

And that's the biggest ISPs, plus he can still use Tailscale or Zerotier and still be able to access his network. Plus IPv6 IPs should be easy to assign and won't be paid or limited.
