Can you provide an example? I’m a little confused by what you mean.

Happy to help!

Side note, if you want to make publicly available services, you could use cloudflare tunnels. They work in a similar way – letting your services be accessible over the Internet without needing to open ports. Some other people in the comments have mentioned that Tailscale funnel can also work for this, but i haven’t used it so I can’t really advise on that front

To my understanding, yes! I touched on it in the post but since tailscale is a VPN that doesn’t require open ports to access other devices in the tailnet, you don’t need to worry about CGNAT
