1、將在線IP自動添加到地址列表

2、實時檢測在線IP數

:local s 0
:foreach i in=[/ip firewall address-list find list=Online] do={:set s ($s+1)}
:log warning ("當前" . $s . "個IP在線")

3、自動對IP做限速

:local s 0
:foreach i in=[/ip firewall address-list find list=Online] do={:set s ($s+1)}
:foreach i in=[/ip firewall address-list find
 
 list=Online] do={:local ip 0;set ip [:ip firewall address-list get $i address];if (/queue simple get [/queue simple find name=$ip] = "") do={:queue simple add max-limit=20M/6M name=$ip target=$ip;log warning ($ip."限速upload:20M,download:6M")}}
