I found only server ports:
Which ports does the TS2 Server use?
TeamSpeak Server is using the following ports:
8767 UDP, Server
location at server.ini: ServerUDPPort=8767
14534 TCP, WebInterface
location at server.ini: HTTPServer Port=14534
51234 TCP, tcpquery port
location at server.ini: TCPQueryPort=51234
To get server to work behind firewall, nat, masq you
need only to open/forward the 8767 port.

But i am looking for clinet ports, i've already checked all FAQ threads.
