I love the Cosmos cases! I’m still using the Cosmos SE for my gaming pc. Computers should have handles!

Tailscale has a NextDNS integration, so I use that to point my made-up internal domain to the Tailscale ip of my NAS. Works well with subdomains. When I’m on my local network (and not connected to Tailscale), my pihole directs the same url to the local ip.

To clarify, when you’re external or on the tailnet, you want the Tailscale ip. On the local network, you want the local ip.
