hola a todos...retomando el tema..
como alesanchez comentaba, los browsers para conectarse a algun ftp se conectan en modo pasivo, y si en tu servidor ftp ya sea proftpd o vsftpd no estan configurados o dados de alta, no se van a conectar, se podran conectar desde algun cliente de ftp, como cuteftp, ftp voyager, etc, siempre y cuando no este habilitado la coneccion pasiva...
en proftpd se configuran agregando la siguiente linea:
PassivePorts (puerto minimo-puerto maximo) , por ejemplo :
PassivePorts 6000 6010
donde el rango de puertos a conectarse van del 6000 al 6010
en vsftpd es un poco mas de lineas:
#
pasv_address — Specifies the IP address for the public facing IP address of the server for servers behind Network Address Translation (NAT) firewalls. This enables vsftpd to hand out the correct return address for passive mode connections.
There is no default value for this directive.
#
pasv_enable — When enabled, passive mode connects are allowed.
The default value is YES.
#
pasv_max_port — Specifies the highest possible port sent to the FTP clients for passive mode connections. This setting is used to limit the port range so that firewall rules are easier to create.
The default value is 0, which does not limit the highest passive port range. The value must not exceed 65535.
#
pasv_min_port — Specifies the lowest possible port sent to the FTP clients for passive mode connections. This setting is used to limit the port range so that firewall rules are easier to create.
The default value is 0, which does not limit the lowest passive port range. The value must not be lower 1024.

recuerda abrir desde el router el rango de puertos pasivos de tu servidor ftp..
