Blocking Source IP Addresses
You can block a source IP address from accessing either all applications or only selected applications by editing policy rules. Then you can view the policy changes by clicking the policy name or view affected devices by clicking the device count. Also, you can click the policy to view the affected rules, edit the rules, and save them, if required.
