我们在
Windows Server 2008 R2上运行FileZilla服务器0.9.37
活动模式正常,服务器上的Windows防火墙已关闭.
我们的路由器是DrayTek活力2820.在NAT,开放端口,我已经为服务器本地IP打开了以下端口
TCP 20-22,TCP 45100-65535
在FileZilla服务器中,在被动模式设置下(我无法发布图像…)
Use the following IP: 213.106.150.123 Don't use external IP from local connections: Checked Use custom port range: 45100-65535
从我在德国的远程服务器,我尝试连接回FileZilla服务器.
Status: Connecting to 213.106.150.123:21... Status: Connection established,waiting for welcome message...

FileZilla服务器上的状态窗口报告以下内容
(not logged in) (87.106.131.22)> Connected,sending welcome message...

如果我将FileZilla被动模式设置从外部IP更改为默认,我会从德国客户端尝试连接时获得以下详细信息.
Status: Connecting to 213.106.150.123:21... Status: Connection established,196,198) Command: MLSD Response: 425 Can't open data connection. Error: Failed to retrieve directory listing
以及服务器上的详细信息.

我究竟做错了什么？
当我指定外部IP时,客户端和服务器报告相同,但端口搞砸了,当我使用默认运行时,服务器使用其内部IP但端口分配看起来更好.
编辑：更多测试及其工作.
所以我在IIS 7.5中安装了FTP服务器,禁用了FileZilla,它工作正常！然后我尝试重新启用FileZilla,这太有用了！这完全来自我家的ADSL连接.
然后我再次尝试从我们在德国的远程服务器失败,挂起在被动模式下的目录列表中,用于IIS FTP和FileZilla.
我想德国数据中心的防火墙/路由器有些问题.我真的不想弄乱远程服务器路由器(我甚至不确定我可以改变防火墙规则作为其托管)我担心企业客户在尝试访问我们的FTP站点时遭受同样的命运.
我建议你尝试使用Windows的FTP或其他安装的客户端在服务器上本地.这样您就可以看到它是网络/防火墙问题还是FTP服务器配置问题.如果命令,还要检查Filezilla服务器的日志文件.
如果它取决于防火墙,这里有一篇TechNet文章可以提供帮助：How to Configure Windows Firewall for a Passive Mode FTP Server.但是您写道Windows防火墙已关闭,所以我认为这是外部防火墙/路由器的问题(也检查客户端).
