5. service ufw restart (重啟iptables)
6. service fail2ban restart (重啟fail2ban)

註：ufw 為Ubuntu下重啟iptables指令, 其它版本Linux 應該都是用iptables

驗證
1. iptables -L -n (即可看到被iptables drop掉的IP)
2. fail2ban-client status asterisk-iptables (即可看到fail2ban監控狀態)
3. iptables -D fail2ban-ASTERISK -s 42.78.174.92 -j DROP (不小心4次驗證失敗IP被加到iptables, 將IP從iptables解放出來)
