ECS 无法通过 负载均衡 访问自己

我的 ECS(e1) 上面搭建了一个 docker mongodb

然后用负载均衡转发了端口 27017.

然后我用本地 telnet 负载均衡 可以访问通, 另外一台 ECS(e2) 可以访问通.

e1 上用本地公网ip 可以 telnet 通, 但是 telnet 负载均衡的时候就不通了.

请问什么问题 有什么地方要设置吗?

e1 上的telnet

[root@iZ23drdpj2tZ active]# telnet i.giccoo.com 27017
Trying 101.37.130.160...
^C
[root@iZ23drdpj2tZ active]# telnet e1_ip 27017
Trying e1_ip...

e2 上 telnet
