LAN (192.168.x.x) is your local network — devices on the same WiFi/router.

Host's LAN IP, Docker's virtual network, and localhost are three parallel, isolated layers.

Communication between layers requires explicit bridges: -p for Docker↔host, port forwarding for LAN↔internet.

To let a friend access your local Besu: router port forwarding → public IP → host → Docker port map → container.
