From TeamSpeak Test Wiki
To setup a Teamspeak server on a Windows server is easy.
 The Installation of the Software
- First you want to download the setup file from the [Teamspeak Downloads Section].
- Next, you simply run the setup file and you will be guided through the install. Make sure to write down the login information that you are given at the end.
- Start the TS server. You will see a purple icon by your clock in the lower right hand side. Right click on the icon and you will see a couple options.
- Click the "Show ip's" option. Write these two numbers down. The one with the computer next to it is your LAN ip, which you will use and anyone inside the lan, and the other is the WAN ip, anyone outside the lan will use this one.
- Now right click on the icon and choose the admin panel. This should cause your internet browser to appear. Unless you have Port Problems or a firewall that is set to deny all for default, you should see the Web Admin panel appear.
- Login in using the superadmin account, make sure the default virtual server is running and then you can exit. For more explanation of the panel go to Web Admin.
Using the Teamspeak client you can test to see if the server is running properly before we configure it so that the rest of the world can access it.
- Open the Teamspeak Client and click connect. Might as well add it to the address book now. ;)
- Right click in the white area and choose "add new server." Now type in the information that you would regularly put in. Make sure for the address of the server that you use the Lan ip for now and not the wan ip.
- If everything is running properly you should be able to move on to making it accessible outside the lan.
 Configuring the Firewall
The are three ports that are used the by the ts server, but only one is needed for talking. That is the udp port 8767. Now most firewalls are different, so instead of me trying to put all of them in here. There is a great site called [Port Forward - Firewall Guides] That details a step by step process to configure Teamspeak with the firewall that you have. For more information about the ports go here.
 Port Forwarding
Now you need the forward the those ports that you made the firewall exceptions for. Yet again, please check out [Port Forwarding - Port Forwarding Guides]. Also make sure that if you have dsl that your modem is not on that list. If it is then that means your modem acts as a router and you will have to configure your modem for port forwarding.
 Now the Final Test
As long as you have properly configured everything and followed the process then you should succeed at this next test. Since most routers do not allow you to use your WAN ip as a address to connect to yourself, we will show you a free service that you can use to test.
- Click on this [link].
- Your wan ip is automatically entered into the test and all you have to do is make sure that ports are correct. Those are the default ports if you change the ports that Teamspeak uses the you will have to change it here.
- Click next.
- Type in the word.
- The results page should appear. As long as you have green for the udp port you are fine, other people can connect to your server. If you are still having problems then you can go to the [Teamspeak Forum] for more support.
