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

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?

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

Jellyfin sees the docker bridge network

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

Jellyfin sees the 192.168.1.1

Q: Why did this work?

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

Jellyfin sees the docker bridge network

Wifi: on tailsacale: of Use exit node: off LAN access: off Jellyfin: LAN IP (via pihole DNS)
