coturn 服务器——处理的传入数据包 BINDING 是什么意思？

Question

我按照教程启动了一个 coturn 服务器：https://meetrix.io/blog/webrtc/turnserver/long_term_cred.html

运行时，我反复向我的控制台发送垃圾邮件：

1915: session 002000000000000009: realm <north.gov> user <1621150194>: incoming packet BINDING processed,

这是什么意思？这是否意味着用户正在尝试访问我刚刚创建的转弯服务器？这没有多大意义，因为它是一个私有服务器，只能通过使用用户名和密码直接引用其公共 IP 来访问。 incoming packet BINDING processed 是什么意思？
