Disabling Streaming Audio/Video on PIX

nukeguzzle — Mon, 11 Mar 2019 08:56:29 GMT

Hello,

I'm looking into disabling streaming audio/video on our PIX firewalls. Does anyone have any information on this? I found a cisco white paper on the internet for disabling P2P software which was very helpful, but would like to disable the streaming media. I've read a little about RTSP and RTP. Is it as simple as blocking those ports?

Thanks,

Also, I am new to this forum and hope to post more in the future. Just looking through some of the posts its nice to see everyone willing to help each other out, and not replying with a cocky attitude that I have seen in some other tech forums.

Need to block blow ports using access-list:

for streaming audio : port no are 18888 ; 6970 (Real)

for streaming video: port no 7000 (VDOlive); 7170 (Real); 1558 (XING-UDP)

for real time streaming protocol it is port no 554 (UDP-RTSP )

for MS NET show: port no 1755 (both UDP and TCP)

For example:

access-list media deny tcp any any eq 18888

access-list media deny udp any any eq 18888

access-list media deny udp any any eq 6970

access-list media deny tcp any any eq 7000

access-list media deny udp any any eq 7170

access-list media deny udp any any eq 1558

access-list media deny udp any any eq 554

access-list media deny tcp any any eq 1755

Watch the word wrap

Also take a look at content services by Trend Micro that work with the PIX
