Question

我正在使用Windows服务器+ Xampp 1.8.3并安装FileZilla FTP Server =＆gt;所有配置都还可以！但是当我将默认FTP的端口（21）更改为另一个端口（30）时，它会发出警告：

我打开了端口20,21,30。

Answer 1

您需要在防火墙中设置被动端口。我不久前写了一篇教程：http://johandorper.com/log/filezilla-server-passive-ports

Answer 2

如果服务器侦听默认端口21，则端口20用作活动模式下数据连接的源端口（此处使用）。根据RFC959,3.2，数据连接服务器的默认源端口为L-1，例如如果L是30，就像你的情况一样，源端口应该是29而不是20，所以你必须允许从端口29连接。

Answer 3

还要检查Windows上的主机文件是否存在无效条目。有一个帮助台的人在他们的主机文件中有一个旧条目到错误的ftp服务器，他们得到了425。

FileZilla FTP服务器错误＆＃34; 425无法打开数据连接＆＃34;将端口21改为30后
