Ftp Performance unusable with Plesk Firewall

[Peter_R]

Hello
i have these problems since version 11.5
now i have installed version 12 on centos

ftp works fine and is super fast and speedy until i enable PLEK FIREWALL,
i also tried to add passive port range 60000-65534 to Plesk Firewall rules.

But nothing Helps

It Takes like 10 times longer to Login + List Files + Make changes using FTP.
Anybody can advise some sort of a fix to this problem?

We applying changes via FTp and its very slow.

we can use plesk file manager but its very inconvenient way for quick file uploads and changes.

Thanks

Forgot to add
once Plesk Firewall is Up, ftp programs having hard time to connect and can not connect with standard setups... like filezilla and other ftp clients
