Describe the feature request

ssh 登录，设置hosts过滤后，被拒绝。

但是可以在服务端可以看到用户建立一个连接：
2021/10/08 11:10:17 [I] [proxy.go:179] [cf0c0b22ae977ada] [ssh] get a user connection [222.90.61.173:6363]

连接报错：
kex_exchange_identification: Connection closed by remote host

目标服务器和代理服务器都有设置。

vim /etc/hosts.allow

sshd:192.168.132.:allow
sshd:222.90.61.173:allow

vim /etc/hosts.deny
