ROS路由器环回脚本，实际在用，只需要更新一个IP地址

实际在用的脚本，需要ros版本较高，低版本可以照着自己改改用，亲测可以。

#取当前拨号ip地址
:global ednsiph [ /ip address get [/ip address find interface="pppoe-out1" ] address ]
:global newip [:pick \$ednsiph 0 [:find \$ednsiph \"/\"]]

#新建回流规则
/ip firewall nat
add action=dst-nat chain=dstnat comment="huiliu" dst-address=$newip\
    dst-address-type=local dst-port=88 protocol=tcp \
    to-addresses=192.168.88.3 to-ports=80
add action=masquerade chain=srcnat comment="huiliu-99" \
    out-interface-list=LAN src-address=192.168.88.0/24


#新建任务，每隔10分钟更新一遍huiliu的目标ip地址
/system scheduler
add name=huiliu comment="\B8\FC\D0\C2\BB\D8\C1\F7\B2\A6\BA\C5\B5\C4IP\B5\D8\D6\B7" \
    interval=10m on-event=":global adsl \"pppoe-out1\"\r\
