ENETUNREACH FTP Error in Filezilla caused by Kaspersky Security Center 10

 Server/client security software is annoying at best but it is even more annoying when things are not clear how to fix a problem much like I had with Kaspersky Security Center 10 and Filezilla.  After a server update a new policy was made and all FTP access was denied from our clients and they needed access for us to continue to do our business.  Here is how to fix the ENETUNREACH Error that you will get if your trying to use Filezilla with Kaspersky.

Filezilla FTP ENETUNREACH Error caused by Kaspersky Security Center 10

If your using Kaspersky Security Center 10 and Filezilla for any FTP services you may require if you don't have a proper policy in place you will encounter the following error

Error: The data connection could not be established: ENETUNREACH - Network unreachable

To resolve the error and allow your users to FTP again you need to make the following changes in your policy.

Right click on the policy and go Properties.

Go to Anti-Virus Protection -> General Protection Settings -> Monitored Ports Settings

De-select/uncheck the FTP port as shown in the image below.

Hit OK then go to Firewall Settings -> Configure Rules for Network Packets and Data Streams

Add a new Network Packet Rule

After you add the rule you can move it to the top of the list to ensure it doesn't get blocked by another rule.  You can also limit this to particular IP addresses if you only want specific users to have access.

Hit Ok -> Hit Apply -> Hit Ok

That's it your done.
