无法使用 Filezilla 通过路由器连接到 FTP 服务器

当我使用 filezilla 连接到我的 Web 服务器时，出现以下错误：

Status: Resolving address of ftp.mysite.org.in
Status: Connecting to 199.199.199.18:21...
Status: Connection established, waiting for welcome message...
Response:   220---------- Welcome to Pure-FTPd [privsep] [TLS] ----------

我使用 cradlepoint CTR35 wifi 路由器连接有线互联网。当我不使用这个路由器连接到同一台服务器时，连接工作正常。

所以我猜我的路由器防火墙设置有问题，但我不知道是什么问题！有人能帮我解决吗？

笔记：服务器需要通过 TLS 显式 FTP并且不适用于普通 FTP 会话。我可以使用普通 FTP 通过路由器连接到其他服务器。

编辑：

好的。这里有一些调试信息。

您将 FileZilla 设置为哪种模式？主动还是被动？

在 NAT 路由器后面，Active 无法轻易工作。

有关更多信息，请参阅 FileZila wiki 条目这里：

主动模式

在主动模式下，客户端打开一个套接字并等待服务器建立传输连接。默认情况下，FileZilla Client 会向操作系统询问机器的 IP 地址和空闲端口号。此配置仅在您直接连接到互联网且没有任何 NAT 路由器时才有效，并且如果您已将防火墙设置为允许所有大于 1024 的端口上的传入连接。
