Problem with new Tailscale install to bypass ISP CGNAT (lemmy.ml)

submitted 5 months ago by [email protected] to c/[email protected]

I have a cloud VPS running Ubuntu with Tailscale installed directly. I also have Tailscale installed on my home server.

I'm trying to access my self-hosted applications from outside my home network which I did easily until I switched to fiber internet that uses CGNAT.

Tailscale is working locally but not outside my home network. A suggestion was to disable IP v4 on Tailscale since it conflicts with the CGNAT IP my ISP is using. However when I add the "disableIPv4": true to the config file in the access control area of Tailscale, I keep getting various errors.

Any help would be appreciated.

I did some more testing and I can access my Nginx Proxy Manager from outside my network. The issue appears to be accessing the self-hosted applications on my home server, mainly Jellyfin. I still think the issue is the IP conflict with Tailscale. NPM is fairly easy to configure and is setup correctly with my domain name.

the way i got around this is to set my DNS settings on my domain to be the IP of my NPM server's tailscale address.

i.e. 100.12.34.56 A record for mydomain.com, but leave all the local addresses the same
