Привет всем.
Есть 5 серверов. Задумка оптимизировать pf.conf. Правила перебрал. Осталось с лимитами разобраться:

set timeout { interval 10, frag 30 }
set timeout { tcp.first 120, tcp.opening 30, tcp.established 86400 }
set timeout { tcp.closing 900, tcp.finwait 45, tcp.closed 5 }
set timeout { udp.first 60, udp.single 30, udp.multiple 60 }
set timeout { icmp.first 20, icmp.error 10 }
set timeout { other.first 60, other.single 30, other.multiple 60 }
set timeout { adaptive.start 0, adaptive.end 0 }
set limit { states 10000000, frags 50000 }
set loginterface none
set block-policy drop
set require-order yes
set fingerprints "/etc/pf.os"

 

При этом, получаю такие результаты:

# /sbin/pfctl -si

Может у кого есть идеи?

Спасибо.
