A new TeamSpeak 3 server version 3.0.7.2 is available. This version contains a hotfix as a countermeasure against recent DOS attacks. These attacks interfere with the way the server handles new client connections and cause very high CPU usages.

– Please download and install the 3.0.7.2 server.
– Login to the query interface with a serveradmin account.
– Issue instanceedit serverinstance_pending_connections_per_ip=2 command.

You may use other low values but we recommend setting it to 2 or 4. Setting this value to 0 will disable the DOS protection.
Please follow all three steps to enable DOS protection as the server comes with DOS protection disabled by default.
