v1.15.23 reference: that update rewrote multiplayer on the current Steam networking API. The dedicated server is a Windows binary (appid 1247090); on Linux it needs Wine plus a persistent xvfb virtual display, and the upstream panel egg now uses 573090 with an account that owns the game. Config lives at server_data/server_config.xml and sets only the first port; the second is port + 1. This site does not implement the game's server query - join via the in-game browser or Join by IP.

Server notes
The server is a Windows binary, so Windows hosting is the least painful path; on Linux it needs Wine plus a persistent xvfb virtual display. server_config.xml cannot be edited while the server runs - restart after every change. Whether port forwarding is required is unproven; a developer reply said traffic may go via Steam. Physics runs server-side on one core, so vehicle complexity usually matters more than player count, and vanilla has no bulk vehicle removal. This page only emits commands and config fragments; it never installs, updates or stops a server.
