ROS多线DDNS脚本

网络状况 18条ADSL线路 PCC+NTH 混合负载模式。 需要PCC+NTH的联系猫哥 地址是 cat-home.org
内网PING 本地外网的18个ip是正常的 外部ping我的外网的18个IP 只有一个是ping得通的，怀疑是ISP的问题。
普通的DDNS脚本在这种环境下就不适用了。请教了猫哥之后，才把多线只通一条的线路的DDNS脚本搞定。
以下是修改后的脚本

#多线DDNS
#DDNS
:global gate [/ip route get [/ip route find static=yes active=yes dynamic=yes] gateway]
:global xxddns {:put [/ip add get [find network=$gate] interface]}
:global ddnsuser "用户账号"
:global ddnspass "用户密码"
:global ddnshost1 "绑定域名1"
:global ddnshost2 "绑定域名2"
:global ddnshost3 "绑定域名3"
:global ddnsinterface $xxddns
:global ddnslastip

:global ddnsip [ /ip address get [/ip address find dynamic=yes interface=$ddnsinterface ] address ]
:if ( [:typeof $ddnslastip]="nothing" ) do={ :global ddnslastip 0.0.0.0/0 }
:if ( [:typeof $ddnsip]="nothing" ) do={
 :log info ("DDNS: No ip address present on " . $ddnsinterface . ", please check.")
} else={
 :if ($ddnsip != $ddnslastip) do={
   :log info "DDNS: Sending UPDATE!"
   :log info [ /tool dns-update name=$ddnshost1 address=[:pick $ddnsip 0 [:find $ddnsip "/"] ] key-name=$ddnsuser key=$ddnspass ]
   :log info [ /tool dns-update name=$ddnshost2 address=[:pick $ddnsip 0 [:find $ddnsip "/"] ] key-name=$ddnsuser key=$ddnspass ]
   :log info [ /tool dns-update name=$ddnshost3 address=[:pick $ddnsip 0 [:find $ddnsip "/"] ] key-name=$ddnsuser key=$ddnspass ]
   :global ddnslastip $ddnsip
 } else={
   :log info "DDNS: No change"
}
}
:log info "DDNS: End"
