I have a Cisco 1811 with IOS Firewall software, I wish to block Adobe Flash to ensure my users will not be able to watch/stream videos from Youtube. I don't want to block the web site but block the watching of the videos. Can anybody help out?
I tried this:
ip inspect name firewall http java-list 99 alert on audit-trail on timeout 10
Access-list 99 blocking the youtube website
