These options are actually for Fail2Ban, the "Max Retry" limits the authentication attempts. "Find
Time" defines the time duration from the first attempt to the last attempt which reaches the
"Max Retry" limitation. "Ban Time" is the time in seconds the IPPBX system will block the IP
which exceedsmax retry.
These settings don't take effect on any allowed addresses.
