Azure VM无法接收传入的SIP请求

Question

我是第一次尝试在Azure VM上运行我的SIP客户端。我已将端点添加到VM以允许SIP流量（UDP 5060）。我已经在Win2012 R2 VM上禁用了Windows防火墙。甚至在VM端点设置中将ACL设置为0.0.0.0/0。

当我从Internet发送SIP INVITE时，我可以在wireshark上看到INVITE，但它从未到达SIP客户端。我甚至试过eyeBeam客户端而不是我的SIP应用程序，结果相同。 Wireshark可以看到INVITE SIP数据包，但它永远不会到达应用程序。

由于wireshark可以看到SIP数据包，我的Azure设置可能没问题。但谁阻止数据包到达SIP客户端？

我从VM尝试了tracert，它返回一个空白，到任何公共IP。例如：

tracert www.microsoft.com

好吧，我解决了这个问题。我发布了Azure端点设置的图像。看到我用红色圈出的选项，应该不选中。我正在选择那个选项，这让我完全搞砸了几天。
