### Port forwarding
On your router, forward **UDP 24242** to the server computer's local
address (give that computer a fixed local address first). Friends join
with your public IP address. It needs no extra software, but your home IP
and that port are public, so set a `password`.

Why two: each land of the journey runs as its own server on the next port
up (24243 is the Cove's, when the server's on 24242). The server players
join (the Valley's) starts it when someone first goes there and stops it
when it's been empty a couple of minutes; everyone still joins on 24242.
Host Game and the server's log both say which ports to forward. With
Tailscale, or on the same Wi-Fi, there's nothing to do.
### A cloud server
Any small Linux server works (it needs little: a couple of GB of memory).
Install Godot, clone the game, use the systemd file, and open UDP 24242 in
the provider's firewall.

handles both; see `docs/SETUP_ON_NEW_MACHINE.md`.

- Next, J3c: a land server crashing (its players back to the hub), and the
Host page's extra ports.
*As built in J3c:*
- A land server that stops (crashed, or killed) tells its players "Lost the
connection to the Cove. Join the server again to carry on there."; the
hub notices it's gone (even mid-join) and joining again starts it afresh
and sends them back (their characters were saved by its autosave).
- The extra ports: `Lands.extra_ports()` / `ports_text()` ("UDP 24242 and
24243 (the Cove)"), on the Host page, in the "You're hosting" message, in
a hub's start-up log, and in docs/HOSTING.md.
- Tested in `test_net_lands.gd` (the Cove's server killed, Alice rejoins)
and `test_worldlet_pick.gd` (the Host page).
