Items Description
Port
The port you want to auto defense, for example, 8022.
Protocol
Select the protocol. You can select UDP or TCP.
Rate
The maximum packets or connections can be handled per unit
time. For example, if you configure it as below:
Port: 8022
Protocol: TCP
Rate: 10/min
Then, it means maximum 10 TCP connections can be handled in
1 minute. The 11
th
connection will be dropped.
IP Blacklist
You can set some packets accept speed rules here. When an IP address, which
hasn’t been accepted in common rules, sends packets faster than the allowed speed,
it will be set as a black IP address and be blocked automatically.
