CIFS (Windows File Sharing)

Common Internet File System (CIFS) is a standard protocol supported by most operating systems in order to share files across the network. Using UPnP port mapping for CIFS allows users to connect from the Internet and use programs like Windows Explorer to access the NSA’s shares to copy files from the NSA, delete files on the NSA, or upload files to the NSA from the Internet.

If you configure UPnP port mapping to allow CIFS access from the WAN but cannot get it to work, you may also have to configure the Internet gateway to also allow NetBIOS traffic. See Section 6.3 on page 153 for more on CIFS.

FTP

File Transfer Protocol is a standard file transfer service used on the Internet. Using UPnP port mapping for FTP allows remote users to use FTP from the Internet to access the NSA’s shares. A user with read and write access to a share can copy files from the share, delete files from the share, or upload files to the share. See Section 9.4 on page 188 for more on FTP. If you use UPnP to allow FTP access from the WAN, you may want to use a different WAN port number (instead of the default of port 21) to make it more secure. Remember to tell the remote users to use the custom port number when using FTP to access the NSA.

HTTP (Web Configurator)

You can use UPnP port mapping to allow access to the NSA’s management screens. If you use UPnP to allow web configurator access from the WAN, you may want to use a different WAN port number (instead of the default of port 80) to make it more secure. Remember to use the custom port number when accessing the NSA’s web configurator from the Internet.

HTTP (Web Published Shares)

This is the NSA’s web publishing feature that lets people access files using a web browser without having to log into the Home screens. Use UPnP port mapping to allow access to these files from the Internet without having to enter a user name or password. See Section 9.7 on page 204 for more on web publishing.
