MY IPS CAN NOT BLOCK THE SKYPE AND MSN SIGNATURES

[r.barba]

I friends I have a Cisco ASA 5520 with an AIM Card (IPS), I have enable the IPS, but It is not working properly because I enable the skype and MSN signatures ( and I put the block inline connection, and TCP reset connection), but all the PCs can login into Skype and MSN, I did the actualkizatiosns, versions, signatures, OS, but the problem continue. How can I solve this Problem????.

If you are sending the traffic to the IPS, and can see hits for the signature "MSN Messenger Activity" and if you only want to block this for certain IP addresses then the solution to your problem is to use 'Event Action Filters' for the existing Signature. By default the signature is disabled so you will have to enable the signature first.
