FileZilla: ENETUNREACH – Network unreachable – how to fix

FileZilla: ENETUNREACH – Network unreachable - come risolvere

A couple days ago I had to solve a strange issue regarding one of our machines seemingly unable to connect to a public FTP server: the PC in question was trying to connect using FileZilla, the well-known open-source FTP Client by FileZila Project available here.  The given error was the following:

ENETUNREACH – Network unreachable

Since the FTP server was perfectly reachable by other machines – also using FileZilla themselves as well – I started to look closer on the client. To cut it short, it turned out that the problem was related to the Kaspersky Antivirus TCP filter, which incorrectly behave with a FileZilla estabilished connection breaking it out.


Luckily enough this is a well-known problem on the FileZilla Project website, which even features a dedicated page explaining how to properly fix it. For your convenience, these are the required steps:

  • Double click on the Kasperskysystray icon (the red “K” near the system clock).
  • From the newly-opened windows, click on the “Settings” tab, then navigate to the “Anti-Virus protection” category.
  • In the new panel that will show, locate and click on “Firewall“.
  • To the right part of the new window, click to the “Application network rules…” button.
  • Click on the “Application” column to filter the items.
  • Browse the item list until you find “FILEZILLA PROJECT“: expand it by clicking to the “+” icon.
  • Click on the “filezilla.exe” entry: an info panel will appear.
  • Click on “Additional…” to show a new window, called “Application control rules“.
  • Click on the “Exclusions” tab and check the following options:
    • Do not inherit restrictions of the parent process
    • Do not scan network traffic

That should do it. If this brief guide isn’t enough, take a look to this great post by tDailyLama on the FileZilla official forum which basically explains it all and also has some pictures on the Kaspersky interface.

Happy connecting!
