1 Make sure the files are a format supported by iTunes. See Section 16.5 on page 160.
2 If you have files from the iTunes Store that use DRM, you need to use your Apple
account ID and password to authorize other computers to play the files. Apple permits
you to authorize up to five computers at a time. To authorize a computer, open iTunes
and click Store > Authorize Computer.
3 If you are connecting through a NAT router, make sure that TCP port 3689 and UDP port
5353 are open for traffic on both the server and the client and all points in between
(especially the NAT router). If your router includes a firewall, make sure it also allows
TCP port 3689 and UDP port 5353 traffic.
15.8 Download Service and Broadcatching Functions
V The download list or broadcatching items are missing after I removed a hard
drive.
The NSA’s download and broadcatching lists are stored on the system volume. If you have
two JBOD volumes, it is possible to remove one and still use the other. However if you
remove the system volume, you may lose the download and broadcasting lists. With two
JBOD volumes, the hard disk that was installed first is usually the system volume.
15.9 Web Publishing
V A web-published share cannot be accessed by web browser from the Internet.
• Make sure the person trying to access the share is using the correct web address (and port
number if the NSA’s web publishing feature is not using port 80). See Section 8.9.2 on
page 102 for details.
• Make sure the publishing feature is turned on and the share is in the list of published
shares.
• Make sure the person trying to access the share is using Internet Explorer 6.0 (and later) or
Firefox 1.07 (and later).
• You need to use a public address to access the NSA’s web-published shares from the
Internet. If your NSA uses a private IP address, use the public IP address of your Internet
gateway (firewall) and configure NAT or port forwarding on your Internet gateway and
possibly firewall rules in order to let people access the NSA’s web-published shares from
the Internet.
• Make sure the firewall’s public IP address is static or that the firewall uses a Dynamic
Domain Name (DDNS).
