Bonjour,
j ai trouve ca sur le web :
pasv_enable
Set to NO if you want to disallow the PASV method of obtaining a data connection.
Default: YES
pasv_promiscuous
Set to YES if you want to disable the PASV security check that ensures the data connection originates from the same IP address as the control connection. Only enable if you know what you are doing! The only legitimate use for this is in some form of secure tunnelling scheme, or perhaps to facilitate FXP support.
Default: NO
pasv_max_port
The maximum port to allocate for PASV style data connections. Can be used to specify a narrow port range to assist firewalling.
Default: 0 (use any port)
pasv_min_port
The minimum port to allocate for PASV style data connections. Can be used to specify a narrow port range to assist firewalling.
Default: 0 (use any port)
pasv_address
Use this option to override the IP address that vsftpd will advertise in response to the PASV command. Provide a numeric IP address.
Default: (none - the address is taken from the incoming connected socket)
Si tu veux le reste de la doc, va a cette adresse :

Voila.
