我用這個的。

不知是否RouterOS 本身的問題，DDNS update 後，雖然見到新IP資料，但我差不多等了15分鐘左右，才能使用解決NAT loopback 問題，即是從local network，在Browser 內直接打 DDNS_Hostname 進入自己網內的NAS 資源。

感覺上RouterOS 的Update 沒有像一般Router一樣能即時反影新的設定。

但用SSL 方式，https://XXX.XXX.XXX:443 就可以馬上進入NAS 的資源，真不明所以。
而普通用 http://xxx.xxx.xxx:8080 用了一會又很容易斷掉 connection.。

假如是Dual Wan or Multiple Wan，如何把不同IP update 指向同一位址呢?
