Can I use CiscoSecure ACS to allow/deny VPN users access to a certain servers? I know that one could use CiscoSecure ACS to allow/deny VPN user to a group(s) of networking devices. But I have not been success with servers? Can you share some thought?
Do you mean after user authenticates to VPN, you want to restrict which servers the users have
access to, if so you need to configure Downloadable ACL, so you can apply this ACL specific to your requirement.
