Connection Limit Statistics
Connection Limit
It enables administrators to inspect the number of established connections in real-time and to justify the maximum
number of connections allowed on [Service] -> [Connection Limit] page, to avoid network congestion.
Automatic Refresh : Select auto-refresh interval, or disable the function.
No. : Numbering of IP addresses based on the number of connections established.
IP : Shows the source IP of the connection.
Connections : Shows the number of connections that are established by the source IP address and
still active in system. An connection in system might be a connection with traffic flow
existing or a idle connection. This number varies from connections closing to newly
opened connections.
Clear : System maintains necessary tables and information for connections. Clicking the but-
ton to abort the connections established by the source IP address, and release the
occupied memory then. When system is under attacks with high volumes of malicious
connections, FortiWAN's Connection Limit (See "
Connection Limit ") stops sub-
sequent connections established by the malicious IP addresses, but it takes time to
recover system from the bandwidth and memory occupied by those malicious con-
nections that are already in system. The Clear button terminates them immediately.
