Hey there! :slight_smile:

Thanks so much for your response. Some of it I don't quite understand, unfortunately. So, I hope you may be able to answer my follow-up questions:

  1. You're saying Vodafone and Cable is the issue, correct? Is that because I'm in a CGNAT? In other words, I share a public IP address with other people? Would internet from Telekom solve this issue? (my sister has that in her home)
  2. In case I stick to Vodafone, you're saying that Tailscale might be an option? Can you tell me what it depends on whether or not that is an option?
  3. In that guide you sent, they mention Astrorelay for people who are "in a CGNAT". Is that something similar / the same as Tailscale?
  4. In case I get a dedicated IP (let's say from Surfshark which I already use) would that significantly simplify this entire process? Can I just always connect to that IP address then with my travel router?

As you can probably tell, I'm quite the noob. So I really appreciate it! :slight_smile:
