I found a article at Microsoft: “Internet firewalls can prevent browsing and file sharing” and there i found all the ports that where used for file sharing:

  • Microsoft file sharing SMB: User Datagram Protocol (UDP) ports from 135 through 139 and Transmission Control Protocol (TCP) ports from 135 through 139.
  • Direct-hosted SMB traffic without a network basic input/output system (NetBIOS): port 445 (TCP and UPD).

And after reading that i started looking at the F-Secure Firewall services again and found two services. “SMB over TCP/IP (TCP)” and “SMB over TCP/IP (UDP)” witch in fact does the same as i did yesterday by opening port 445.

So, I’m sorry to have blamed F-Secure before checking better but after finding the “Windows file sharing and network printers” service i just didn’t think about looking for an SMB service, sorry, my bad.

On the other side, i think that thees services should have another name because a normal user probably don’t know what SMB is, but might still want to share files. So a tips to -F-Secure this time is to give this services a better name.

The F-Secure service named “Windows file sharing and network printers” only open TCP port 139 while Windows file sharing wants to use TCP port 445. So I created a new service for port 445 and added it to the rule and then file sharing worked fine…

I think TCP port 445 should be added to the “Windows file sharing and network printers” service.

Update:

I was wrong. Sorry, my bad.

I just found out that the File sharing rule don’t work at all. I previously stated i use F-Secure Client Security 9.0 BETA on a Windows 7 x64 RTM client.

The RDP Rule is still working, and i have created a new rule for a random port to test and that worked to.
So it’s just the file sharing rule for Windows File sharing that don’t work.

How i created the rule:

  • Add new rule
  • Name: “File sharing”
  • Allow
  • All IP addresses
  • Service: “Windows file sharing and network printers”
  • Both ways
  • No alert
  • Finish

Can there be something wrong with the “Windows file sharing and network printers” service?
