Specify access to the USB storage device: 

Network Device Name. This is the name used to access the USB device connected 
to the router. The default is readyshare.

workgroup name is displayed here. The name works only in an operating system that 
supports NetBIOS, such as Microsoft Windows.

Network Neighborhood/MacShare. Enabled by default.

HTTP. Enabled by default. You can type 
http://readyshare.routerlogin.net/shares to access the USB device.

HTTPS (via Internet). Disabled by default. If you enable this feature, remote 
users can type http://<public IP address/shares> (for example, 
http://1.1.10.102/shares) or a URL domain name to access the USB device over 
the Internet. This feature supports file uploading only.

FTP. Disabled by default.

FTP (via Internet). Disabled by default. If you select this check box, remote users 
can access the USB device through FTP over the Internet. This feature supports 
both downloading and uploading of files.
