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.
28.14 Download Service Functions
The download list items are missing after I removed a hard drive.
The NAS’s download list is 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 list. With two JBOD volumes, the hard disk that was installed first is usually the
system volume.
I cannot find the download files.
By default, the Download Service feature stores downloaded files as follows:
• P2P download jobs are stored in /*/incoming (where ‘*’ is a folder that you have set.)
• HTTP/FTP jobs are stored in /* (where ‘*’ is a folder that you have set.)
• All jobs triggered by RSS channels create the subfolder in /* using the channel name where it
store all files downloaded from that channel (where ‘*’ is a folder that you have set.)
Check your Preferences in the Download Service ( Section 17.7 on page 219 ) screens to know or
configure where downloaded files are stored.
28.15 Web Publishing
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 NAS’s web publishing feature is not using port 80). See page 240 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 NAS’s web-published shares from the Internet. If
your NAS 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 NAS’s web-published shares from the Internet.
