Uhm pasv, Some FTP packages require you to open additional ports if you are using PASV for FTP server. Example: When you connect to your FTP server initially it talks on port 21, as soon as PASV kicks in the port switches over to something like 1024, so you see.. (xxx.xxx.xxx.xxx,1024) FTP servers like G6 FTP Pro allow you to disable PASV mode so that you never have to worry about opening additional ports on you firewall.
