# Game Filters: Per-Game DDoS Protection

These filters go beyond general packet filtering: they verify traffic using a challenge-response mechanism, effectively blocking attack traffic that would otherwise appear legitimate to a generic filter. All game filters listed below are enabled by default for the specified port ranges.

## Available game filters

<AccordionGroup>
  <Accordion title="FiveM (TCP/UDP)" icon="car">
    **Protocol:** TCP and UDP

    **Default ports:** 30000–32000

    FiveM protection operates at Layer 4 by default. A Layer 7 filter via our Layer 7 Cluster is also available request it by opening a support ticket.

    **Layer 7 filter behaviour:**

    * Caches `/info.json`, `/players.json`, and `/dynamic.json` for 1 minute
    * Custom modded content is not cached
    * Strict rate limits are enforced, clients that exceed the limit are banned for 8 hours
  </Accordion>

  <Accordion title="Minecraft Java (TCP)" icon="cube">
    **Protocol:** TCP

    **Default ports:** 25565–26000

    Covers the standard Java Edition port range. Only traffic matching the Minecraft Java protocol is permitted on these ports.

## Requesting a custom game filter

If your game is not listed above, Packets Decreaser can implement a custom filter tailored to its protocol.

<Info>
  Contact support with the game name, protocol (TCP/UDP), and the port range your server uses. The team will assess whether a dedicated filter is feasible and advise on implementation.
