I created an FTP server on my local Windows 7 machine with IIS.

I can connect to the server with the machine on which I created the server, but I can't connect to the server with my laptop which is in the same local network as the machine with FTP server on it.

I configured passive mode in FileZilla and port forwarding on the router.

But the problem is always the same:

Connection timed out

Any ideas?

    Any software firewalls on the machine? Have you checked IIS is listening for all IP's? Port forwarding is not necessary within the same local network. – Jonno Jan 22 '16 at 8:44
  • Yes it was the firewall problem. Thank you for help. – Matic1911 Jan 23 '16 at 20:55

The connection is most probably blocked by the Windows firewall.

While the Windows firewall is automatically configured with rules for the ports 21, 990 and 1024-65535, when IIS FTP server is installed, the rules are not enabled initially.

To enable or change the rules, go to Control Panel > System and Security > Windows Firewall > Advanced Settings > Inbound Rules and locate three "FTP server" rules. If the rules are not enabled, click on Actions > Enable Rule.

For details, see my guide for Installing a secure FTP server on Windows using IIS.

  • Thank you for that it works now! Do you know how can I configure client to use only port 21? Because now I have passive mode enabled and ports between 50000 - 51000. – Matic1911 Jan 22 '16 at 15:54
  • You are welcome. Though on Super User we thank by accepting the answer. – Martin Prikryl Jan 22 '16 at 15:55
  • Can you please see my updated question? – Matic1911 Jan 22 '16 at 15:56
  • The problem is that when I connect from client with FileZilla the port is random between 50000 - 51000. I need port to be 21 because I wrote a proxy for educational purpose and I would like to listen to traffic. – Matic1911 Jan 22 '16 at 16:01
  • FTP protocol needs a separate port for data connections. You cannot do with only port 21. You can reduce the data connection port range to a single port number. But it has to be distinct to 21. – Martin Prikryl Jan 23 '16 at 8:11
