Hi Efiten,

IP/port combinations have to be unique, by default Wowza will bind to all IP’s that are available. To override this you can configure your VHost.xml

file to use a specified IP. In your VHost.xml file change:

```auto
<IpAddress>*</IpAddress>

```

To:

```auto
<IpAddress>[you-ip-address]</IpAddress>

```

You will need to change this for all the host ports setup in your VHost.xml file.

Also, IIS binds to all IP addresses.

Take a look at the windows command line utility netsh for managing IP addresses that IIS binds to.

Salvadore
