Interesting IPs between Jellyfin clients and server depending on tailscale and server address

#homelab #linux #tech

When connecting from my phone to jellyfin I'm seeing some interesting patterns.

Scenarios

Tailscale IP of phone is listed as local network to jellyfin

Wifi: off Tailscale: on Use exit node: on LAN access: on Jellyfin: LAN IP

Jellyfin sees 192.168.1.1, my router address

Wifi: off tailscale: on Use exit node: on LAN access: on Jellyfin: Tailscale magic DNS

Jellyfin sees the docker bridge network

Q: This might be because of traefik somehow

Wifi: off tailsacale: on Use exit node: on LAN access: off Jellyfin: LAN IP

Jellyfin sees the 192.168.1.1

Q: Why did this work even work?
