[已解決] 運行在 ESXi下的 RouterOS，無法更新DDNS！

各位網兄

小弟架設ESXi 跑RouterOS

ESXi 網路架構如下圖



VMNIC0 為WAN；VMNIC2為LAN

ROS設定PPPOE及其他

PC端可以正常上網

但是卻不能更新DDNS，小弟用的DDNS 是 ChangeIP
SCRIPT為GOOGLE來的，如下:
=============================================================================
:log info "DDNS: Begin"
:local ddnsuser "ID"
:local ddnspass "PWD"
:local ddnshost "XXXXXX"
:local ddnszone "myddns.com"
:local ddnsinterface "pppoe-out1"

:global ddnslastip
:global ddnsip [ /ip address get [/ip address find interface=$ddnsinterface] address ]

:if ([:typeof [:global ddnslastip]] = nil ) do={ :global ddnslastip 0.0.0.0/0 } else={ :set ddnslastip $ddnslastip }
:if ([:typeof [:global ddnsip]] = nil ) do={
:log info ("DDNS: No ip address present on " . $ddnsinterface . ", please check.")
} else={
:if ($ddnsip != $ddnslastip) do={
:log info "DDNS: 開始更新DDNS!"
:log info ([/tool dns-update key-name=$ddnsuser key=$ddnspass name=$ddnshost address=[:pick $ddnsip 0 [:find $ddnsip "/"] ] zone=$ddnszone] . "更新IP：" . $ddnsip)

:global ddnslastip $ddnsip
} else={
:log info "DDNS: IP無變動"
}
}
:log info "DDNS: End"
=============================================================================


更新失敗的LOG


同樣的SCRIPT在另外一台 VM Workstation下面的 ROS 卻可以正常更新
搜尋了好久都找不到解答
求助各位網兄指點
謝謝了~~
