Arma 3 Server Config Generator
Build a complete Arma 3 server.cfg with the security defaults Bohemia recommends — BattlEye, verifySignatures=2, the safe extension whitelists for loadFile/preprocessFile/htmlLoad, and signature-tamper kick handlers wired up. Seven tabs (Identity, Players, Voting, Security, Behaviour, Mission Cycle, Advanced) cover every documented field. Mission rotation builder generates the nested class Missions { class … } block correctly. Four presets: secure public, private friends-only, modded coop, headless-client friendly. Outputs a download-ready server.cfg with version-gated comments. Verified against the Bohemia community wiki.

};FAQ
Where do I put server.cfg?
Anywhere your dedicated server has read access — you point to it with the -config=path/to/server.cfg startup parameter. There is no default location; the file is only loaded if -config is specified.
Why is upnp marked as a warning?
Per the Bohemia wiki: "this setting may delay server start-up by 600s (standard UDP timeout of 10 minutes) if blocked on firewall or bad routing." Always disable upnp if you've manually port-forwarded — which you must do on a managed host like xgamingserver.
Is equalModRequired included?
No — Bohemia explicitly marks it as "Outdated". Modern servers should rely on verifySignatures = 2 instead, which is forced even if you set verifySignatures = 1.
What's the safe extension whitelist?
The de-facto-standard list of file extensions that are safe to load via loadFile / preprocessFile / htmlLoad on a public server. Restricting these blocks several script-injection vectors. Keep the toggle on unless you're running mods that explicitly need other file types.
How do I add an admin without giving them the password?
Add their Steam UID to admins[] in the Identity tab. Whitelisted UIDs can use #login with no password (since Arma 3 1.70). Server admins are first-come-first-served — only one logged-in admin at a time unless BattlEye RCon is in use.
Mission template format?
missionName.terrainName — e.g. MyMission.Altis for a PBO at MPMissions/MyMission.Altis.pbo. For addon missions loaded via mods, use the class name registered in CfgMissions, not the folder name.
What about basic.cfg / arma3.cfg?
Different files. basic.cfg tunes networking (MaxBandwidth, MaxMsgSend) and is set via -cfg. arma3.cfg is the per-profile settings file. This tool generates only server.cfg.
