I need to stop my internal users from using AOL, MSN and Yahoo instant messenger clients. I understand it can be done using QOS but I have not been able to get it working correctly. I see how I can stop MSN and Yahoo by using the âserviceâ option but how do I stop AOL? Also, I need to stop IMs even if the user changes the port, any ideas?
My ASA is running 7.2(2) and I am willing to upgrade if needed.
Thanks in advance!
