if your problematic situation is same as below:
ftp client - internet (wan) - m0n0wall - lan - ftp server

you must do:
ftp server - set port range for PASV (eg.20000-20100)
m0n0wall - define incoming rules for ftp (open TCP port 21) and PASV (open
TCP port range 20000-20100)

I use guildftpd, my config is:

and my two rules are:
pass TCP  *  *  myserver  21
pass TCP  *  *  myserver  20000 - 20200

I face the problem that I cannot list the files in ftp server. That ftp
server is behind the m0n0wall.

I think that this is Passive Mode problem. How can I fix this problem ?
