我正在设置家庭 FTP 服务器，以便我可以与局域网外的朋友共享一些文件。我正在使用 filezilla 服务器，并且已配置好一切。http://www.canyouseeme.org/甚至看到我的端口 21 已打开，但是当我通过 fit 客户端或通过 Web 浏览器连接时，它会显示“530 用户 saravana 访问被拒绝”。
我该如何解决这个问题，我检查了用户名和密码，一切都很好，但我没有发送任何被动模式，（我不知道如何设置），如果这导致了麻烦，有人可以帮助我，但我可以通过本地主机进行本地连接。

答案1
考虑到您提到的所有内容以及日志中的信息：您正在尝试通过公共地址连接到 ftp 服务器，该地址是不正确我不会详细介绍数据包路由和其他内容，只会用简单的话来讲述：
- 公共（WAN）地址用于外部世界
- 私有（LAN）地址用于企业网络
因此，如果您设置了 ftp 服务器，只要它位于您的公司网络内，就使用私有地址连接它。
或者，如果您确实想使用相同的公共地址连接它，则需要在路由器上设置路由表，这样它就会将 IP 转换为不同的地址（所谓的 NAT）。
答案2
您可以进入路由器的设置页面，配置通过端口 21 的每个外部连接，并将其重定向到您的 filezilla 服务器。这称为 NAT。
