Thanks for replying, I am using zeroshell 1.0.beta10 (which is quite old, I know – but updates for some reasons failed) Connection tracking is active, I do not know anything about modules… even though the latter one you mentioned sounds interesting.

This is my current configuration for FTP:

BRIDGE00 * ACCEPT tcp opt — in BRIDGE00 out * 192.168.10.0/24 -> 0.0.0.0/0 tcp dpt:21 no
BRIDGE00 * ACCEPT tcp opt — in BRIDGE00 out * 192.168.10.0/24 -> 0.0.0.0/0 state RELATED no
BRIDGE00 * ACCEPT tcp opt — in BRIDGE00 out * 192.168.10.0/24 -> 0.0.0.0/0 tcp dpt:20 no
BRIDGE00 * ACCEPT tcp opt — in BRIDGE00 out * 192.168.10.0/24 -> 0.0.0.0/0 LAYER7 l7proto ftp no

Active FTP works just fine – but passive FTP does not for some reason. Some servers my clients would like to connect to only allow PASV connections so I wonder what I am doing wrong… Any more hints?
Thanks in advance!
