FTP problem solved! Well, simple answear would be much more time saving for me…
So everyone who need help with FTP issues, here are simple steps to get it work (both passive and active modes works).
From the web GUI:
1. Fire Wall -> NAT: add standard FTP rule, in my case:
WAN TCP 21 (FTP) 10.1.1.xx (ext.: 212.xx.xx.xx)
2. Fire Wall -> Rules: Beside the automatic rulles created by pfSense add one more.
TCP * * 127.0.0.1 8000 - 8020 * (permitted traffic to 127.0.0.1 on ports 8000-8020)
3. Interfaces -> LAN: Ensure that the FTP helper box is NOT checked.
4. Interfaces -> WAN: Ensure that the FTP helper box is NOT checked.
Knowing this I could save a lot of time, irritation and head acke. I hope this info help other users!
