当有非TURN连接候选者可用时，为什么选择TURN服务器？

Question

我在同一网络上有两个客户端。它们具有相同的IP地址。当我启动它们之间的两个对等连接并等待ICE连接“连接”时，然后查看连接字符串并发现 TURN SERVER 是连接IP。如果我从ICE服务器列表中卸下TURN服务器，则连接有效，但最终使用其共享IP地址结束。因为我希望选择公共IP，所以这似乎是不可取的且不必要的。

为什么将TURN服务器列为连接IP？如何防止使用TURN服务器？

>它甚至被使用还是仅被用作连接字符串，而数据包实际上并没有经过它（从而使它们的成本为0）？

我还注意到我的TURN服务器目前正在使用非常少的CPU和带宽，因此我不确定它实际上是否在以任何方式使用。

如果我在VPN后面更改其中一个的公共IP地址，也会发生相同的情况：1.它们在服务器列表中有和没有TURN服务器的情况下都可以使用，但是2.在可用时选择TURN服务器。< / p>

这是在将转向服务器添加到ICE服务器列表中时ICE连接状态为“已连接”时我的候选项和连接的列表。
