如何连接局域网外的ftp服务器？

Question

我正在设置家庭ftp服务器，这样我可以与我的朋友分享一些文件在我的局域网外。我正在使用filezilla服务器和所有配置。http://www.canyouseeme.org/甚至认为我的端口21是开放的，但是当我通过fit客户端或网络浏览器进行连接时，它的意思是"530用户saravana访问被拒绝“。

我如何解决这个问题，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)，如果这是造成麻烦，谁能帮助我，我可以通过本地连接方式通过本地主机。

Answer 1

考虑到您提到的所有内容和日志中的信息:您试图通过您的公共地址连接到ftp服务器，这是不正确的。我不会详细讨论分组路由和其他事情，只会用简单的话说：

• 公共(广域网)地址是面向外界的。
• 专用(LAN)地址为公司网络

因此，如果您设置了ftp服务器，只要使用私有地址连接到它，如果它驻留在您的公司网络中。

或者，如果您真的想用相同的公共地址连接到它，您需要在路由器上设置路由表，这样它就会将IP转换成不同的地址(即NAT)。

Answer 2

您可以转到路由器的设置页面，通过端口21配置每个外部连接，然后重定向到您的文件服务器。那叫纳特。
