Block Youtube streams

Good Day every one.

I am a network administrator and i am offering limited bandwidth to my clients. But the problem is i some of them like to misuse their bandwidth and i dont want that. So i was wondering if there is a way to block off streaming videos. cos i’ve tried my best.
i’ve barred all *.mp4, *.flv and even *.swf.

Please help me. as when others are viewing these videos other complain of low speed.

So the main thing is other than setting a bandwidth limitation and barring the whole website is there any there way i can ban streaming videos?

instead of blocking such websites, you should give each customer a speed limit, so that they don’t disturb others. PCQ is a good solution:

I have already defined their limits. I was just wondering if there was another was to block the streams. Thanks for the reply. :smiley:
