ROS路由器环回脚本，实际在用，只需要更新一个IP地址-526互联

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
