Windows 10: Firewall blocking port 21 even though IIS FTP server is enabled

Hello!

I'm puzzled. If I turn off windows firewall I can hit the FTP server from the WAN fine and even from the LAN. Turn the firewall back on and that port is blocked! When I installed IIS for the FTP server I added (ticked the boxes) for FTP Server in the firewall.

The $64,000 question is this; why is the firewall being a pest?

Thanks!

Update: I added my own inbound rule for ports 20-21. I can connect via the WAN but the LAN says it's blocked. What am I missing????

:)

 

W10 IIS FTPS (Secure) Can't run passive mode port forwarding unknown

OS Windows 10 Pro, I have installed IIS FTP on my PC. I can run FTP from an client running fine but NOT Secure. So I "Create Certificate Request" (CCR) send it to my certificate provider. In return I get my certificate. Then I install my certificate "Complete
Create Certificate Request" On my IIS\FTP I active my certificate an run under active "required secure connection" ok

Keep in mind I have only port 21-22 forwarded to my PC

Now I start from client FTPS (Secure) then is stop..

27 Entering Passive Mode (192,168,2,1,4,98).

Server reports local IP -> Redirect to: xxx.xxx.xx.xxx

ISS (Secure) block the passive mode.

QST

I there somebody that can tell me witch port I have to forwarded

Thx Robert

 

NSU Error Message

Check with your rpivider that your proxy supports FTP (port TCP 21 traffic). Nokia Software update uses port 21 firstly (Active FTP), will then try passive FTP, and will then try 80 (HTTP). It is known that NSU has problems with connecting through proxy
servers, so if problems persist and you cannot disable your proxy, please try taking the phone to one of your relatives and try performing the update there.

Clearly, in your case, the proxy is the bottleneck...

 

Strange as it is, I had to make my own inbound firewall rule for this to work. The builtin one must be there for show. It's windows! Go figure!
