N8N on Raspberry Pi with Starlink & OVH DNS - IP and DNS Modification Issues

Questions
1

Hello everyone,

I’m posting this message because I’m encountering significant difficulties setting up my project and I’m hoping to find some help from the community.

My goal is to host an instance of n8n on a Raspberry Pi. This Raspberry Pi is connected to Starlink via Ethernet.

I’m facing two major problems, which are likely related:

  1. IP Issue with Starlink: As you probably know, Starlink uses a dynamic and shared public IP address (CGNAT), which makes direct external access to my Raspberry Pi via its public IP impossible. I am well aware of this limitation and am looking for solutions to work around it.

  2. OVH DNS Modification Problem: I own a domain name with OVH. I’ve tried to configure a DNS redirection to point to my Raspberry Pi, but I’m unable to change the IP address associated with the DNS entry. The IP address remains fixed to the old configuration, and I can’t seem to update it, even after several attempts and waiting periods.

In summary, I want to be able to access my n8n instance hosted on my Raspberry Pi (behind Starlink) from the internet, using my OVH domain name.

I imagine the solution involves an approach to bypass Starlink’s CGNAT (VPN, SSH tunnel, services like ngrok, etc.) combined with adequate DNS configuration at OVH.

Do you have any leads, advice, or similar experiences to share that could help me solve these problems? Any help would be greatly appreciated.

Thank you in advance for your time and expertise.
