以下是configuration。
Client is a linux server IP: 10.204.21.143. This server is only reachable to HA Proxy server. HA Proxy Server IP: 10.204.24.71 (Its a Solaris 11.3 Server) Back end Server where the FTP Server is running : 10.212.22.31 This server is only reachable to HA Proxy Server only and not to Client Server. HA代理configuration：
$ cat haproxy.cfg global maxconn 15000 pidfile dmshaproxy.pid daemon stats socket dmshaproxy.sock mode 0600 level admin spread-checks 5 defaults mode tcp retries 3 maxconn 15000 contimeout 5s clitimeout 300s srvtimeout 300s option contstats listen FTP 10.204.24.71:2121 server ftp-serv00 10.212.22.31:21 check inter 20s $
现在我可以从客户端连接，执行cd命令，它工作。 但是ls不起作用。
[root@qa-lt143 ~]# ftp 10.204.24.71 2121 Connected to 10.204.24.71 (10.204.24.71). 220 ::ffff:10.212.22.31 FTP server ready Name (10.204.24.71:root): oracle 331 Password required for oracle Password: 230 User oracle logged in Remote system type is UNIX.

我看到，当我做了后端IP连接，这是从客户端服务器无法访问。 不知道为什么不采取HA代理服务器IP。
此外，我也尝试了与主动连接相同，然后也没有工作。 这次它花了本地服务器IP。

请帮忙。
