共享上网FTP服务提示错误550

局域网内服务器安装双网卡,其一设置外网IP、网络共享。其二设置内网IP,作为局域网网关,共享上网。
现在问题是:我在主机上设置了ftp服务,访问ftp://内网IP,输入用户名和密码,正常访问,但是输入ftp://外网IP,则提示“550”错误。
谁能告诉我到底是那里的错误,如何才能解决?
用外网IP一直提示 550 /incoming:permission denied.
用局域网IP测试可以通过。

执行如下命令
ftp>cd incoming
ftp>mkdir foo
ftp>cd foo
ftp>put foo.txt
输出什么调试信息呢? [/quote]

都没有间题.信息如下:
