Securing TeamSpeak Server Query Port from DDoS
The TeamSpeak ServerQuery (default port 10011) is a powerful tool for automated administration, bots, and monitoring services. However, it is also a primary target for DDoS attacks and brute-force attempts. In the 2026 security meta, an unsecured Query port can lead to server shutdowns or "Permission Escalation" exploits. This guide covers how to harden your Query interface.
๐ก๏ธ Flood Protection
By default, TeamSpeak allows too many commands per second. An attacker can spam the login command to exhaust the server's thread pool.
๐ IP Whitelisting
Only the IP addresses of your authorized bots or web panels should be allowed to even "see" the Query port.
Technical Hardening Steps
1. Update Flood Limits
Log into your TeamSpeak server using a Query Client (like YaTQA) and navigate to Anti-Flood settings. Adjust the following values to prevent rapid-fire exploits:
# Recommended settings for 2026
Commands per 1s: 10
Points per command: 50
Points for ban: 5002. Bind to Localhost (Recommended)
If you only use local scripts (like a server monitor on the same machine), you should bind the Query interface to 127.0.0.1. This prevents anyone from the outside world from reaching it. Edit your ts3server.ini:
query_ip=127.0.0.13. Using SSH Tunneling
If you need remote access but want ultimate security, keep the Query port closed in your firewall and use an SSH Tunnel to connect. This encrypts your administration session and provides a second layer of authentication.
ssh -L 10011:localhost:10011 your-server-ipSecurity Tip: TeamSpeak 6 introduces a new REST API that should be used instead of Raw Query whenever possible. The REST API supports Modern Bearer Tokens and granular Scopes.
Professional Hosting Security
A manual firewall setup is often not enough to stop 1:1 Query floods. At Supercraft, we use a specialized Voice-DDoS Shield that filters TeamSpeak traffic at the edge, ensuring your Query port only accepts legitimate traffic from verified sources.
