#Windows 10 ftp server passive mode windows
It's quite common though that the FTP server is behind a NAT. The Windows FTP command-line client (ftp.exe) does not support the passive mode, on any version of Windows. Proceed to the end of the wizard and click Install. Make sure that Management Service > IIS Management Console is checked. Check FTP Server > FTP Service role service. The client should connect to that IP/port to initiate the transfer. In Windows Server Manager go to Roles node and in Web Server (IIS) > Role Services panel click Add Role Services.
The server responds with its IP address and port number. If that's the case, most usual problem is that some firewall (or the NAT) on the way between you and the server blocks the connection attempt to the data port (as reported in the response to the PASV command). The error showing the server is behind the NAT and need to enable passive mode. To establish a data connection for a file transfer or a directory listing, an FTP client (in the passive FTP mode) sends PASV command to the server. Though as you mention that "Browsing is nearly impossible", it looks like that it does not help. So in most cases, you won't notice the problem at all. When encountering this, FileZilla tries to connect to the primary address of the FTP server instead, as that is usually the correct address to use. You should see the offending address in the FileZilla log: FileZilla does too and reports the mentioned message. The FTP server must report its external IP address, that can be used outside the NATted networks.Īs this is unfortunately a common issue, many FTP clients try to detect this (by checking that the reported IP address is within the range of addresses reserved for local communications within a private network).
It's clearly a misconfiguration of the FTP server. When it reports such IP address to a client outside the NAT, the IP address is obviously of little use. (In active mode the server connects back to the client in passive mode the client connects to the server but the general mechanism remains the same. And it's aware of its local address within its NATted network only. 1 Answer Sorted by: 0 FTP performs data transfer through dedicated TCP connections on randomly-allocated ports.
