Manage the Blocked Sites List (Blocked Sites)

The Firebox System Manager (FSM) Blocked Sites List tab shows the IP addresses of all the external IP addresses that are temporarily blocked by your Firebox. Many events can cause the Firebox to add an IP address to the Blocked Sites tab: a port space probe, a spoofing attack, an address space probe, or an event you configure.

The Expiration column for each IP address shows the time when the address is scheduled to be removed from the Blocked Sites tab.
