I'd like to know how do I able my teamspeak 3 to your dns?

1. Sign up for dynamic DNS service for your domain name https://www.dynu.com/en-US/ControlPanel/AddDDNS and keep the domain name mapped to the most current IP address of your Team Speak server using an IP update client at https://www.dynu.com/DynamicDNS/IPUpdateClient

2. Set up port forwarding for the port on which the Team Speak server runs in your router by referring to https://www.dynu.com/Resources/Tutorials/DynamicDNS/RouterandDevices/RouterPortForward

3. Access your TeamSpeak server using the domain name and port
