Hi,
I had a followup question to Sam's answer below, but maybe it never made it to the list...

That's already the case. You may set an upper limit on the number of connections from the same IP address, or from the same /24.
I couldn't find this in the documentation, what is the setting for this upper limit on number of connections?
MAXPERC and MAXPERIP variables, set in the configuration file.
Also, this limit is based on certain window of time? What time frame constitutes "too many connections"?
The time frame is "at any given time". Connections from the same IP address or the same /24 where there are already the maximum number of existing connections, are rejected.
