Protecting Your Hytale Server: Anti-Cheat and VPN Blocking

Protecting Your Hytale Server: Anti-Cheat and VPN Blocking

As Hytale explodes into the gaming scene with its massive 2026 early access launch, the unfortunately inevitable wave of malicious actors follows close behind. Hackers utilizing aimbots, killaura, fly-hacks, and X-Ray resource packs will attempt to ruin the experience for legitimate players. Griefers will try to crash your world, and bitter rivals might even attempt to launch DDoS attacks against your IP.

Running a successful Hytale dedicated server requires far more than just high-performance hardware—it demands a fortress-like approach to security. In this guide, we dive deep into the essential configuration methods, server-side anti-cheat integration, and VPN blocking techniques required to keep your community safe.

The First Line of Defense: DDoS Protection

Before an attacker even logs into your server, they might try to take it down completely using a Distributed Denial of Service (DDoS) attack. If you host a server from your home network, your personal router will crash, cutting off your internet access entirely.

This is the primary reason why serious communities rely on professional hosting. Providers like Supercraft utilize enterprise-grade firewalls and Anycast networks to absorb massive traffic spikes. When choosing a host, ensure they specifically mitigate UDP attacks, as Hytale communicates extensively over UDP (port 5520).

Server-Side Anti-Cheat: How It Works

Unlike client-side anti-cheats (like Riot Vanguard or Easy Anti-Cheat), a Hytale server relies heavily on server-side verification. The server must constantly double-check the math of every action a player attempts.

Enabling Strict Movement Validation

By default, the server gives clients a slight benefit of the doubt to prevent rubber-banding due to high latency. However, hackers abuse this leniency to fly or move with impossible speed. You can tighten these constraints in the server's configuration files.

"security": {
  "enforce_movement_validation": true,
  "max_speed_tolerance": 1.15,
  "prevent_noclip": true
}

Setting `enforce_movement_validation` to true ensures the server calculates whether it's physically possible for a player to reach point B from point A within a given timeframe. If not, the server aggressively rubber-bands the player back to their valid position.

Implementing Custom Anti-Cheat Plugins

While the built-in validation is strong, the CurseForge plugin ecosystem is incredibly proactive in developing advanced heuristics. Community-developed anti-cheat plugins analyze combat patterns: if a player consistently lands critical hits on multiple targets surrounding them within milliseconds ("Killaura"), the plugin will silently flag, ban, and log the incident.

Always ensure your anti-cheat plugins are updated. Plugins are Java code that runs inside the server, so keep them as current as the server itself.

Ban Evasion, VPNs and Proxies

In Hytale a ban belongs to the account. /ban stores the player's account UUID in bans.json; this build has no IP ban command. A VPN or proxy therefore does not get a banned account back in. Evading a ban means signing in with another account, and the real defences are:

• The whitelist. Turn it on with /whitelist enable and add only people you know, with /whitelist add. A new account cannot join.
• A join password. Set Password in config.json and share it only with your community.
• The join permission. With RequireJoinPermission on in config.json, a player needs the hytale.server.join permission, which you grant to trusted players or a group.

If you do want to filter connections by IP address, do it where the traffic arrives: with firewall rules on the server's UDP port, or with your host's network protection. A plugin could also check addresses, but that means writing Java against the server's plugin API; see Does Hytale Support Lua? for how plugins work.

Backups: The Ultimate Failsafe

No matter how many plugins you install or how strict your VPN blocking is, a zero-day exploit could still slip through and result in a ruined spawn city. In these moments, your only salvation is a recent, uncorrupted backup.

Use an automated scheduler to back up your `universe/worlds` folder at least every 6 hours. Store these backups externally. Premium hosts automate this process entirely, ensuring that if catastrophe strikes, your community's progress is only set back by a few hours rather than losing months of effort.

Conclusion

Securing a Hytale server is an ongoing war of escalation between administrators and malicious users. By laying a foundation with enterprise DDoS mitigation, enforcing strict server-side physics, and automating the blocking of bad IP addresses, you create a safe haven for your legitimate community to thrive.
