Multiple subs-domains on same ip and ts3 connect

[gorilliaz]

Hi
I own a dedicated server, above I have site, 1 teamspeak and other service with each a subdomain
The problem is that each subdomain can be used to connect to the teamspeak.
Do you know how to make only my ts.domain.com address the only one that can connect
Thanks

Create prerouting tables after allow prerouted ip, and drop all traffic.

Would you have an example?
