我的 2 个地址（简称 A 和 B ）都是同城电信千兆宽带（百兆上传），之前发现 A 地址的上传被限速到 10M （上传 1MB/s ）
然后打 10000 后和 it 后台人员理论后，先说找不到问题，然后我发了 A 和 B 宽带互测的 iperf 的截图和理论当前电信官网的测试白名单机制后，过了一周多，直接收到工单完成的短信。
于是我用之前被限速的测速网站后，发现上传是恢复了……（吗？）
在 B 宽带处用 iperf 通过 tailscale 测试连接的速度后。发现 A 宽带还是被限速到 10M 。
然后我用 iperf 通过公网 ip 来测（要开高位端口才行，默认端口连不通），发现 tcp 的限速有时候被取消了。但是 udp 的还是一直被限速。
之所以说有时候，是因为测了一会，就可能会触发限速
通过公网直接从 B 宽带的测试结果（反向模式，A 传输给 B ，测试 A 的上传）：

应该是 tailscale 的隧道是走的 UDP ，所以不管什么流量都会被封装在 tailscale 的 UDP 里。
另外好奇为什么公网直接 UDP 传输速度全部是 0 ？
