What it fixes

Crash

World-state crash storm

A forged world-state network event crashes every player that receives it, so one cheater can take the whole server down in seconds. The server now refuses to relay it.

Crash

Fake parachute task crash

A forged parachute task is pushed into the sync data, and every player who streams that entity crashes. The update is dropped on the server and never reaches anyone.

It never bans anyone by itself. It drops the forged packet and reports the sender. With FeloxAC installed, the sender is punished automatically.

Requirements

  1. FXServer artifact exactly 38435. Check it with the console commandversion
  2. Access to your own server files. Managed hosts that lock them cannot use this build.
  3. Any game build from 2060 – 3570 works. If you don't set one, FXServer starts on its newest game build, which this release doesn't cover yet. Pick a supported one in server.cfg, for example:set sv_enforceGameBuild 3570

Install

  1. Stop the server.
  2. Next to FXServer.exe, rename the original file so you can go back later:citizen-server-state-fivesv.dll → citizen-server-state-fivesv.stock.dll
  3. Copy citizen-server-state-fivesv.dll from the zip into the same folder.
  4. Start the server and run this in the console. It prints 2 when the fix is active.fac_netGuard

Turn off or revert

set fac_netGuard 2Block (default)
set fac_netGuard 1Only report the sender
set fac_netGuard 0Off

To revert, stop the server and rename citizen-server-state-fivesv.stock.dll back to citizen-server-state-fivesv.dll.
