Playback Security Client Restrictions

Hi,

I’m ussing Wowza Streaming Engine Pro 4 for Amazon EC2 4.6.0 build19395.

I have an Application with four Incoming Streams. Publising is protected by password.

I can playback all streams with VLC without problem from anywhere.

Now I want restrict the playback by IP ( by net could be even better)

To do that I’m ussing Playback Security -> Client Restrictions. I set Only allow playback from the following IP addresses with a single IP. Buy I can playback the streams from anywhere anyway.

Any ideas?

Thanks in advance.
