全部，
我曾經是 ZoneAlarm 的快樂用戶。然而最近我需要在我的一台機器上開啟一個連接埠（Windows 8.1，SQL Server 的連接埠 1433），我發現這顯然是一項不可能的任務。所以，我詢問並被告知要使用 CoMoDo。
我確實下載並安裝了它，但現在看起來我仍然無法遠端存取伺服器。 CoMoDo 和 Windows FW 都處於活動狀態，我認為我確實在它們上開啟了相關連接埠。但是，嘗試遠端登入電腦的連接埠 1433 會導致「連線逾時」。
所以，我的問題是 - 如何在 Windows 8.1 韌體和 CoMoDo 韌體中正確開啟連接埠？
我還應該補充一點，這是用於我家裡的本地區域網路。
謝謝。

答案1
為了讓一切順利，您應該轉送 TCP/UDP 1433 和 1434。
透過建立自訂規則來開啟路由器和防火牆中的這些規則。將連接埠新增至規則清單時，必須指定協定和連接埠號碼。建立連接埠規則時，您可以僅指定 TCP 和 UDP 端口，這足以滿足您的需求。
幾乎：
- 開啟Windows防火牆
- 點選高級設定。系統可能會要求您輸入管理員密碼或確認您的存取權限。
- 在“進階安全性 Windows 防火牆”對話方塊的左窗格中，按一下“入站規則”，然後在右窗格中點擊或按一下“新規則”。
- 按照螢幕上的指示添加我指定的連接埠之一，並對其他連接埠重複此操作。
對於科摩多：
防火牆->進階->網路安全策略->全域規則。選擇“新增”，然後為每個連接埠新增規則：
行動：允許
協議：TCP
方向：進/出
來源位址：任意
目的地地址：任意
來源連接埠：任意
目的連接埠：1433
對所有人重複。
