Intrusion Prevention System/ASA Blocking Devices Problem
SSM-20 IPS Module installed on the ASA 5520. Shunning works great when problem is detected from outside interface to inside interface.
Here is my problem. When remote VPN users connects (VPN Client/outside interface) and a problem is detected the VPN client address is shunned (172.16.X.X) on the ASA but the system can still connect to inside systems because they are at that point on the inside LAN.
I don't have any Cisco 6500 switches that that is not an option. Can I create some sort of access list on my ASA or Cisco 3750 switches to deny access ??
