FileZilla FTP的被动模式不起作用

我们有Windows服务器2008 R2上运行的FileZilla服务器0.9.37

主动模式工作正常，服务器上的Windows防火墙已closures。

我们的路由器是一个DrayTek vigor 2820.在NAT，打开端口，我已经打开了以下端口的服务器本地IP

TCP 20-22，TCP 45100-65535

• FTP用户隔离问题
• FTP站点与IIS 7.0中的站点
• 推送更新到现场服务器… FTP不会削减它…一个更好的方法？
• Windows 7上的Windows防火墙阻止活动的FTP客户端
• 如何loggingFTP用户使用Pure-FTPD和Apache进行的操作？

在FileZilla服务器，在被动模式设置（我不能发布图像，所以…）

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RDP的德国远程服务器上，我尝试连接到FileZilla服务器。

 Status: Connecting to 213.106.150.123:21... Status: Connection established, waiting for welcome message... Response: 220 -- Command: USER ftp_001471 Response: 331 Password required for ftp_001471 Command: PASS ******** Response: 230 Logged on Status: Connected Status: Retrieving directory listing...

Error: Failed to retrieve directory listing 

FileZilla服务器上的状态窗口报告如下

 (not logged in) (87.106.131.22)> Connected, sending welcome message... (not logged in) (87.106.131.22)> 220 -- (not logged in) (87.106.131.22)> USER ftp_001471 (not logged in) (87.106.131.22)> 331 Password required for ftp_001471 (not logged in) (87.106.131.22)> PASS ******** ftp_001471 (87.106.131.22)> 230 Logged on ftp_001471 (87.106.131.22)> CWD / ftp_001471 (87.106.131.22)> 250 CWD successful.

如果我将FileZilla被动模式设置从外部IP更改为默认，我会从德国的客户端获得以下详细信息。

 Status: Connecting to 213.106.150.123:21... Status: Connection established, waiting for welcome message... Response: 220 -- Command: USER ftp_001471 Response: 331 Password required for ftp_001471 Command: PASS ******** Response: 230 Logged on Status: Connected Status: Retrieving directory listing...

Error: Failed to retrieve directory listing 

和服务器上的细节。

(not logged in) (87.106.131.22)> 220 -- (not logged in) (87.106.131.22)> USER ftp_001471 (not logged in) (87.106.131.22)> 331 Password required for ftp_001471 (not logged in) (87.106.131.22)> PASS ******** ftp_001471 (87.106.131.22)> 230 Logged on ftp_001471 (87.106.131.22)> CWD / ftp_001471 (87.106.131.22)> 250 CWD successful.

我究竟做错了什么？

当我指定外部IP的客户端和服务器报告相同，但端口被搞砸了，当我用默认运行服务器使用其内部的IP，但端口分配看起来更好。

编辑：更多的testing和它的工作。

所以我安装了FTP服务器在IIS 7.5中，禁用FileZilla，它的工作！ 然后，我尝试重新启用FileZilla，也工作！ 这是从我家的ADSL连接。

然后，我再次尝试从我们在德国的远程服务器，它失败了，挂起在IIS FTP和FileZilla被动模式的目录列表。

我想德国数据中心的防火墙/路由器有一些问题。 我真的不想弄乱远程服务器路由器（我甚至不知道是否可以修改防火墙规则，因为它的托pipe）我担心企业客户尝试访问我们的FTP站点时遭受同样的命运。
