DLNA Media Server 
 
 
 
QNAP DLNA Media Server is developed by QNAP. To allow DLNA media players to access and play the 
NAS multimedia content via QNAP DLNA Media Server, enable the QNAP DLNA Media Server and 
configure the Media Library and the default user account.  
 
Note:  
The contents allowed to be browsed on devices connected to the media server are based on the 
shared folder permission set for the default user account. Viewers can only watch multimedia 
contents from the media folders that the default user account is assigned the permission with. 
For media folder setup, please refer to the chapter on Multimedia Management. For permission 
assignment, please refer to the chapter on Shared Folder.  
If you upload multimedia files to the default folder but the files are not shown in the Media 
Player, click Rescan content directories or Restart server on the DLNA Media Server 
configuration page.

Tips for slow BT download rates or download errors:  
1. The torrent file has expired, the peers have stopped sharing this file, or there is error in the file. 
2. The NAS has been configured to use a fixed IP but the DNS server is not configured or it has 
failed. 
3. Set the maximum number of simultaneous downloads as 3-5 for the best download rate. 
4. The NAS is located behind a NAT router. The port settings have led to slow BT download rate or 
no response. You can try the following means to solve the problem: 
a. Manually open the BT port range on NAT router. Forward these ports to the LAN IP of the 
NAS. 
b. Recent NAS firmware supports UPnP NAT port forwarding. If your NAT router supports UPnP, 
enable this function on the NAT. Then enable UPnP NAT port forwarding of the NAS. The BT 
download rate should be enhanced.
