Uhhmm …. But this is not the case .... I have only referenced the <brutefroce>
table once. Complete rules:
table <bruteforce> persist counters
#
# Specific options for exposed services
#
exposed_tcp = "(max-src-conn 10, max-src-conn-rate 15/5, overload <bruteforce>
flush global)"
exposed_udp = "(max-src-conn 30, max-src-conn-rate 10/1, overload <bruteforce>
flush global)"
