Do you have the passive ports open in your FireWall if not, then you have to open them.
Usually Pasive Ports are at: 49152 - 65534

You should take care on what ports to open to the general public, I don't recommend to open them to the general public, what I have done is to open that ports just for the countries of my customers and close for the rest that are not.

Ok, thanks
Done as you said.

Just in case needed, this is what I do for my customers to use the passive ports.

Inside CSF configuration, go to:
CC_ALLOW_PORTS = CA,US
and add the Country codes that you want to allow the passive ports. Example: CA,US

Then on the following line write the FTP ports that you want your ALLOWED countries to connect:
CC_ALLOW_PORTS_TCP = 20,21,49152:65534

What Country Code listing are you using?
It could be that the listing that you are using doesn't has all the Russian IPs.

Does your customer from Russia changes IP very often?

If not, then try to add a rule manually in CSF under "Temporary Allow/Deny" option, like this:

ALLOW IP address: 85.46.87.2 to ports: 20,21,49152:65534 for: 3 days

You can change the days as you wish, just give it a try.
