a01--RouterOs內部架站的轉址設定

有些時候，我們喜歡利用虛擬IP架設網站，但又想要外面也可以訪問得到這台伺服器。
這時，就需要利用Nat轉址。Ros內建轉址功能。
範例：
對外公開的網址 163.23.55.66
內部真正的伺服器網址192.168.2.156

RouterOs啟用代理伺服器proxy---方便管理電腦教室

電腦教室的網路管理是資訊組龐大的業務之一

如果您有使用RouterOs，建議可以啟用代理
伺服器proxy---方便管理電腦教室
以下介紹簡單啟用步驟

設定網頁瀏覽規則
範例：國內教育性質的網站，都允許  *.edu.tw
Ros的代理伺服器規則，最大好處是host名稱，接受*萬用字元
＊意思是全部

放置一些允許的規則後
最後面加一條 全部禁止的規則
這樣，只有教師允許的優良網站，學生才能瀏覽
往後要新增允許的網站，就放在這一條前面即可

教師機不用受管制
所以上面新增一條，教師機完全通過的規則

新版Rb450g與Rb850x2沒有master port

網卡master port 

以前只要勾選此項目，就能串連不同port
例如 你port2 和port3要串連起來，讓他們互通
你可以在port3勾選port2的網卡即可


新版Rb450g與Rb850x2沒有master port 了（我找不到）
你得透過橋接的方式

將要串接的port都放入同一個 Bridge
