[plug] re: FTP Passive mode

[Simon Scott]

Newbie answer: I dont even know what Passive Mode is, but I do know that if
you are passing this through some form of iptables DNAT, you need to load the
ftp module so  it can track the connection properly

Just on the off chance Im somewhere in correct area ;)
