网址[https://tsngusj.jruvznsf.com/n5aym]有时候能封住，有时候封不住，测试把这个情况复现出来了，流量有进系统，无缺失流量的情况，穿透时sapp没有对流量进行处理，捕包分析客户端上的TLS1.3协议，从sapp捕包分析来看，协议是TLS1.2的协议；怀疑流量进入系统后TLS协议有变化？
|
|||
|
|
|
|||
|
|
这是在客户端捕的包，TSLV1都是可以正常封堵的，当客户端请求包TLS协议为TLS1.3的时候就穿透了

这是在服务器捕的包，TLSv1都是正常，{color:#ff0000}穿透的时候server里TLS就是1.2了{color}

这是对应的策略，sni拦截策略

穿透原因：穿透的流中，SNI位置靠后，sapp未识别到SNI所以穿透，现场打了ssl.so的补丁，测试后不再穿透。TLS 1.3的穿透是因为TLS 1.2被阻断了，自动变到了TLS 1.3.
