Rule. The type of rule that defines the behavior of the connections.

Connection limit per second

Some settings in regards to the connection limit per second rule are:

Total connections per source IP. The number of connections allowed in a particular time frame per client or source IP address. This option acts like a soft limit.
Limit Burst. The maximum allowed connections per source IP address before the limit of 1 per second starts blocking. This option acts as a hard limit.

Total connections limit per source IP

Total connections limit per source IP. The summation of connections allowed to a client or source IP address.

Check bogus TCP flags

There are no global settings available for this rule.

Limit RST request per second

Limit RST request per source IP. Several TCP packets with the RST flag enabled that are allowed per client or source IP address. This acts like a soft limit.
Limit Burst. The maximum allowed RST packets per source IP address before the limit of 1 per second starts blocking. This acts like a hard limit.
