Entering PASV when account is Active

[robert]

I have an FTP account that can only be accessed using active FTP, but Filezilla enters PASV anyway.

Here are the account parameters:

host:entertainment-northwest.com
port:21
username and password withheld

servertype: default, autodetect
no bypass proxy
default local directory and default remote directory blank
no adjust server timezone

transfer settings / mode: active
no limit number of simultaneous connections

charset autodetect

This is a windows server running ftp service (lunarpages).

My hardware/software setup is follows:

• Panda antivirus/firewall, applicable ports open, can connect to PASV ftp with no problems, filezilla set to inbound/outbound

• windows xp sp2, intel core 2 duo conroe, 2gb ram, sata boot drive, sata optical, raid5 storage

• network route:
  1. Intel(R) 82566DC Gigabit Network Connection, obtain IP address & DNS automatically
  2. D-Link DGS-2208 gigabit switch, unmanaged, no configuration, no dhcp or other features
  3. LinksKey LKR-604 broadband router, provides DHCP, ip address 192.168.0.1, WAN port to cable modem
  4. Motorola surfboard modem, SB5101
