That helped, thanks.

I added the following to /etc/vsftpd/vsftpd.conf:

  pasv_enable=YES
  pasv_min_port=50001
  pasv_max_port=50010

My firewall script now has the following stanza for FTP:

  # FTP
  $MOD ip_conntrack_ftp
  $IPT -A INPUT -p tcp -i $IFACE_LAN --dport 21 -j ACCEPT
  $IPT -A INPUT -p tcp -i $IFACE_LAN --dport 50001:50010 -j ACCEPT

So the firewall problem seems solved.

Cheers,

Niki
