Generally, if you want to block smth and don't know what to match in your signature rules, just use any kind of packet caputre, look at that capture file using wireshark or smth like that. Find some unique fields/patterns. Then write signature (based on regex, for example) matching that pattern. I personnaly did that for team-viewer, skype and some other things.</P></BODY></HTML> Tue, 19 Feb 2013 07:28:46 GMT https://community.cisco.com/t5/network-security/dynamic-proxy-blocking-through-ips/m-p/2196680#M54058 Andrew Phirsov 2013-02-19T07:28:46Z
