The created groups will appear in a list near the bottom of this page. Users within these groups will also be displayed.

Quotas
Assign Quotas to users and groups. A quota is the maximum amount of hard drive space you wish to allow each user or group to use. Click on the 'Edit' icon on the right hand side of each user or group to set the quota. Click 'Apply' when finished. Near the bottom, either start or stop the quota function.

Select either User or Group.
User or Group
Select a user or group from the pull down list. Select 'All Accounts' if you wish to create a rule that applies to all users.
Folder
Click "Browse" to select a folder. This folder must be located on the internal drives.
Permission
Assign "Read Only" or "Read / Write" permissions to the selected folder for the selected user or group.
Oplocks
Opportunistic locks (oplocks) are a characteristic of the LAN Manager networking protocol implemented in the 32-Bit Windows family of operating system environments. Oplocks are guarantees made by a server for a shared logical volume to its clients. These guarantees inform the Client that a file's content will not be allowed to be changed by the server, or if some change is imminent, the client will be notified before the change is allowed to proceed.
Oplocks are designed to increase network performance when it comes to network file sharing however when using file-based database applications it is recommended to set the share oplocks to No(off).
What operating systems are affected by Oplocks?
By default Vista has Oplocks enabled and can not be disabled. If you are having network performance issues with applications sharing files from the DNS-323 you may try to improve performance by setting Oplocks to No(off).
Map archive
When enabled, the file attribute--"Archive" will be copied as the file is being stored on the DNS-323. Certain backup softwares attach this attribute to files that are being stored as backups.
Comment
Additional comments about this rule. This is optional and has no functional effect.
Click 'Save Settings' to save the rule. All saved rules will appear in the list near the bottom of this page. Rules can be edited or deleted by clicking on the 'notepad with pencil' or 'trash can' icon to the right of the rule.
Click 'Reset Network Access List' to reset the network access list to default access rights. The access right is by default open (no password required) for all accounts.

FTP Server
The DNS-323 also supports FXP (File Exchange Protocol). FXP is a method of transferring data from one remote server to another server using the FTP protocol without first routing the data through the client's PC. Conventional FTP is a single server to a single client architecture. All data is transferred between the server and the client. In an FXP session, the client establishes and maintains a FTP connection both servers, and then it directs either server to connect and initiate data transfer to the other server.
Category
Select either user or group.
User
Select a user or group from the pull down list. Select 'All Accounts' if you wish to create a rule that applies to everyone. Anonymous will always be listed as a user.
Folder
Click "Browse" to select a folder and assign this folder to the selected user. This folder must be located on the internal drives. If you wish to assign access to the root of all drives simultaneously, put a check in the 'root' box.
Permission
Assign "Read Only" or "Read / Write" permissions to the selected folder for the selected user or group.
Click 'Add' to add the rule to the list. All saved rules will appear in the list near the bottom of this page. Rules can be edited or deleted by clicking on the 'notepad with pencil' or 'trash can' icons to the right of the rule.
Max User
Enter the maximum number of users that will be allowed to access the FTP server at one time. The default value is 10.
Idle Time
The FTP server will log a user out if he exceeds the specified idle time.
Port
If you wish to change the port that the FTP server uses, enter in the new number here. This is an advanced setting and a change can cause complications when behind a router. It is recommended to leave this at the default of 21 unless you have experience with changing the FTP port.
Passive Mode
There are 2 modes that can be used when using FTP: active and passive.

In active mode, the FTP client opens a dynamic port and transmits to the FTP server the port number on which the FTP client is listening on. Then the FTP client waits for a connection response from the FTP server.

In passive mode, the FTP server opens a dynamic port and transmits to the FTP client the FTP server's IP address in which the client needs to connect to, and the port on which the server is listening on. It then waits for a connection from the FTP client.

In this section, you can set the port range for which to use in passive mode. In addition, you can choose whether or not to report of the external IP of the FTP server when using passive mode.

Flow Control
This function will adjust the data flow through the FTP server. If you set a limit here, users may download from the FTP server at a slower speed, however, you will conserve local bandwidth.
Client Language
Most standard FTP clients like Windows FTP, only support Western European codepage when transferring files. Northern European, Central European, Traditional and Simplified Chinese as well as Cyrillic codepage support has been added for non standard FTP clients that are capable of supporting these character sets.
SSL/TLS
Secure Sockets Layer (SSL) and Transport Layer Security (TLS) are 2 cryptographic protocols that provide security and data integrity for communications over the Internet.

To enable SSL/TLS on the FTP server, please check the "Allow SSL/TLS connection only" checkbox, and only SSL/TLS connections will be allowed over FTP.

Click 'Save Settings' when finished.

UPnP AV SERVER
The DNS-323 has a built-in UPnPAV media server that can be used with UPnP AV compatible media players.
UPnP AV Server

Folder
Click 'Browse' to locate the root folder of your media files (music, photos, and video). Root can be chosen if you want to have access to all content on the DNS-323.
Click 'Save Settings' when finished.

iTunes SERVER
The iTunes server will allow iTunes software to automatically detect and play music from the DNS-323.
iTunes Server
Enable or Disable the iTunes Server.
Folder
Click 'Browse' to locate the folder which contains your music files. Root can be chosen if you want to have access to all folders of the DNS-323.
Password
When accessing the DNS-323 from iTunes, you will be asked for a password. This is where you can set the password. By default, it's 'blank'.
Click 'Save Settings' when finished.

DHCP SERVER
The DHCP server can be used to serve IP addresses to devices on a network. Do not use this feature if you already have a DHCP server, such as a router, on the network.
DHCP Server
Enable or disable the DHCP server.
Starting IP Address
Enter the first IP address you would like to distribute on the network.
Ending IP Address
Enter the last IP address you would like to distribute on the network.
Lease Time
The duration of time that an IP address will remain assigned to a device. After this time expires, a new IP address will be given.
Click 'Save Settings' when finished.
The DHCP Client List will show all devices that are receiving DHCP from the DNS-323. Click 'Refresh' to update this list.
LLTD
Select enable or disable to turn LLTD on or off.
LLTD
Link Layer Topology Discovery allows the DNS-323 to be discovered by Windows Vista's network map. (Note: Enabling LLTD may cause decreased network performance. If you are experiencing decreased network performance try disabling LLTD.)

Backup encryption
To encrypt files using a secure 256-bit encryption key before backing them up online, choose "Use an automatically generated encryption key" or increased security, you can optionally secure your files further, with a secret passphrase that is known only to you, by selecting "Use my own secret passphrase" and entering a secret passphrase. Your passphrase is completely confidential, and the Online Backup Service does not retain it online or offline.
