To see IP addresses that are blocked when the limits you set on FTP parameters have been exceeded, you can review your log messages, or you can connect to your device with Firebox System Manager and view the Blocked Sites list and Traffic Monitor. From there you can see which IP addresses were blocked and why, and unblock the sites as appropriate. For more information about the Blocked Sites list and Traffic Monitor, see Manage the Blocked Sites List (Blocked Sites) and Blocked Sites and Traffic Monitor.
