具有私有和外部 IP 的 WinNAT

我已經使用 Microsoft guide設置了 WinNAT 。在我嘗試將192.168.33.20專用網路的第二個本地 IP 地址添加到同一個 NIC 之前，一切正常。

當我從帶有 IP 的 VM192.168.0.2向外部網路發出請求時，NAT 只是使用第二個添加的 IP 192.168.33.20，而不是我正確的外部 IP 11.22.33.20。

如何使 NAT 轉換ExternalSourceAddress為正確的外部 IP 地址並忽略本地私有 IP？

我沒有看到您為 Microsoft 指南提供的連結中列出了您的方案。正確的設置需要您添加額外的 NIC 並為其分配您想要使用的私有 IP 地址，而不是使用一個具有多個 IP 地址的 NIC。
