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:
<IpAddress>*</IpAddress>
To:
<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.
