9.6 The PPPoE Screen
Use this screen to configure PPPoE settings for a direct Internet connection. Click Network > PPPoE in the navigation panel to open the following screen.
Figure 85 Network > PPPoE
WAN Port When you enable WAN access for one of the NSA’s services, specify the port number (1~65,536) Internet uses need to use to connect to the Internet gateway’s WAN port in order to access the service on the NSA. Whoever wants to access a service on the NSA from the Internet must use this port number.
BitTorrent’s WAN port must be the same as the LAN port.
Make sure there is not another service using TCP protocol with the same port number. See
Appendix C on page 407 for a list of common services and their associated protocols and port numbers.
If another device is using the same port (the Internet gateway has the same port number mapped to another LAN IP address), the NSA overwrites it when you apply the setting and WAN users can no longer access the other device.
This icon means the service’s LAN and WAN port numbers must be the same.
This icon means another service is using the same port number as this service. Change the port number of one of the services so they use different port numbers.
This icon means another service is using the listed port, but the port the other service is using will be replaced if you apply the setting. The other service will no longer be accessible from the listed port.

Applications
10.1 Overview
This chapter discusses the features in the Application screens. The NSA contains various applications for file sharing and downloading.
10.2 What You Can Do
• Use the FTP Server screen (Section 10.4 on page 184) to configure settings for FTP file transfers to/from the NSA.
• Use the Media Server screen (Section 10.5 on page 185) to share files with media clients. • Use the Download Service screen (Section 10.6 on page 190) to download files from the
Internet.
• Use the Web Publishing screen (Section 10.7 on page 202) to publish shares for people to access files using a web browser.
• Use the Broadcatching screen (Section 10.8 on page 203) to download frequently updated digital content like TV programs, radio talk shows, Podcasts (audio files), and blogs.
• Use the Print Server screen (Section 10.9 on page 209) to share a printer.
• Use the Copy/Sync Button screen (Section 10.10 on page 211) to transfer files between a USB device and the NSA.
• Use the Package screen (Chapter 11 on page 225) to set up additional applications in your NSA. The NSA can download multiple packages/files at once and automatically goes through all the installation steps.
• Use the Auto Upload screens (Chapter 12 on page 275) to upload files in selected shares to your Flickr and/or YouTube accounts.
• Use the Dropbox screen (Chapter 13 on page 289) to synchronize and back up your Dropbox account.
10.3 What You Need to Know
FTP
File Transfer Protocol (FTP) is a file transfer service that operates on the Internet. A system running the FTP server accepts commands from a system running an FTP client. FTP is not a secure protocol. Your file transfers could be subject to snooping.
FTPES (File Transfer Protocol over Explicit TLS/SSL)
File Transfer Protocol over Explicit TLS/SSL (FTPES) is a file transfer service that uses either TLS (Transport Layer Security) or SSL (Secure Sockets Layer) for secure transfers across the Internet. It requests for a mutual method of encryption from the FTP server for its file transfer sessions. Your FTP client must be set to use FTPES as in the following example.
Figure 86 FTP Client Example
DLNA Media Server
The media server feature lets anyone on your network play video, music, and photos from the NSA (without having to copy them to another computer). The NSA can function as a DLNA-compliant media server. The NSA streams files to DLNA-compliant media clients such as gaming consoles, networked TVs, DVD players, stereos, home theaters, satellite boxes, set-top-boxes, mobile phones, portable music players, and multimedia tablets. The Digital Living Network Alliance (DLNA) is a group of personal computer and electronics companies that works to make products compatible in a home network.
iTunes Server
The NSA iTunes server feature lets you use Apple’s iTunes software on a computer to play music and video files stored on the NSA. You can download iTunes from www.apple.com.
Download Service
The NSA’s download service downloads files from the Internet directly to the NSA. You do not have to download to your computer and then copy to the NSA. This can free up your computer’s system resources.
The NSA can download using these protocols. • HTTP: The standard protocol for web pages. • FTP: A standard Internet file transfer service.
BitTorrent
The NSA includes a BitTorrent client for fast downloading and sharing of large files (such as educational public domain videos). With BitTorrent, you share while you’re downloading the file. BitTorrent breaks up the file and distributes it in hundreds of chunks. You start sharing the file as soon as you have downloaded a single chunk.
Web Publishing
Web publishing lets you “publish” shares (containing folders and files) on the NSA so people can access the files using a web browser without having to log into the Home screens. This way you can share files with others without them having to know and enter a username and password.
For example, if you want to share photos in a FamilyPhotos share, you could “web publish” it and others could use a web browser to access the photos at http://my-NSA’s-IP-Address/MyWeb/ FamilyPhotos.
Broadcatching
Broadcatching is the downloading of digital content from Internet feeds. Use broadcatching to have the NSA download frequently updated digital content like TV programs, radio shows, podcasts (audio files), and blogs.
RSS
RSS (Really Simple Syndication) is a format for delivering frequently updated digital content. A channel uses a feed to deliver its contents (items). Subscribe the NSA to a feed to be able to download the contents.
