I am using Netware 6 sp3 with BorderManager 3.7. I am trying to BLOCK streaming audio into our business but I am not having any luck.

I have created filters, specifically in the DENY list to block ports:
554 TCP
1024 TCP
1720 TCP
6790-6999 UDP

I also made rules in BM to block those specific ports.
I noticed that the 554 is still getting through..
using Etherpeek, I noticed that the port dynamically changed from 1024 to 1157...

Can I get some help on blocking ALL streaming audio?
