4.2 TCP/IP Settings
TCP/IP handles network communications between network nodes that are connected to the network.
It is important to setting up correct TCP/IP setting that for NAS server to function properly.
Network Teaming Mode
The NAS server provides two on-board 10/100/1000 or Gigabit Ethernet ports (LAN1 & LAN2). You
can configure the Ethernet ports using the following operating modes:
Stand Alone: Each LAN1 & LAN2 are configured with a unique IP address, which are independent to
each other.
Fault Tolerance: Uses LAN2 to take over for the LAN1 if LAN1 is fail to connect to the network which
designed to ensure server availability to the network.
Load Balancing: Offers increased network bandwidth by allowing transmission to multiple
22
destination addresses using both LAN1 and LAN2. If the traffic of one of the LAN port starts to get
congested, requests are then forwarded to the other LAN port with more capacity until the traffic of
both LAN ports start to get balance. Note that only the LAN1 Ethernet port receives incoming traffic.
Load Balancing also incorporates Fault Tolerance protection.
Link Aggregation: combines both LAN1 & LAN2 into a single channel, appearing to use a single
MAC address to provide greater bandwidth. It must be used with a network switch having the Link
Aggregation or Trunking function.
Wake-On-LAN
NAS server also supports Wake-On-LAN (available for LAN2 only). Wake-On-LAN allows
administrators to remotely power on your NAS server to perform maintenance task on the server with
no need to go to the server physically.
Configuring TCP/IP Settings
1. Select a Network Teaming Mode from the pull-down menu that suit you need.
2. Enable or Disable Wake On LAN (Available for LAN2 only).
3. Click the Obtain IP settings automatically radio button to obtain IP addresses of your NAS server from DHCP, BOOP
or RARP server on the network.
4. Or, click the Use the following IP settings radio button to assign the IP addresses manually.
5. Note that LAN3 IP address field will appear only when the optional Gigabit Ethernet adapter is installed in your system.
6. Input the WINS server IP address.
7. Input the DNS server IP address.
8. Input the DNS Suffix.
9. Input the NTP Time Server IP Address if available.
10. Click Apply to save the setting.
To disable a LAN port, enter 0.0.0.0 in its IP address field. If you happen to disable all LAN ports and
cannot access the administration page, please use the LCD panel to change the IP address to
non-zero values.
23
4.3 Windows Settings
NAS server using SMB/CIFS protocol- short for Server Message Block/Common Internet File System,
a protocol used by Microsoft to share files, directories and devices with the Windows client.
You can configure the Windows Network Settings using the following operating mode:
Workgroup Mode: NAS server becomes a member of a workgroup and communicates with the
clients using its internal user database for authentication and do not require other authentication
server present in the network.
Domain Mode: NAS server become member of a domain and communicates with the client using the
user database stored in an authentication server which must be present in the network Optionally,
you can register the NAS server to the domain. Once registered, the NAS server will be created as a
machine account on the domain controller. And it will use Kerberos as the authentication mechanism,
which provides better integration into the Windows network environment.
Configuring Windows Network Settings
1. Click the Enable Windows Network (SMB/CIFS Protocol) checkbox to enable access for SMB client.
2. Enter the Workgroup/Domain name. Use FQDN if you want to configure NAS server in Domain Mode Ex:
Microsoft.com
3. Click the Workgroup Mode radio button if you want to configure NAS server in Workgroup Mode.
4. Or, click the Domain Mode radio button if you want to configure NAS server in Domain Mode.
5. Input the domain manager’s user name and password (Power Users at least)
6. Select the option to disconnect idle connection automatically. Server will disconnect the
connections which have been idle for 5 minutes if this option is enabled.
7. Click Apply to save the setting.
24
4.4 UNIX/Linux Settings
NAS server can export shares to UNIX/Linux client via NFS protocol. UNIX/Linux client then can
mount the shares and gain access to the content of the shares. UNIX/Linux client uses UNIX user
identification, typically consisting of User Identifier (UID) and Group Identifier (GID), for access
control. Non-NFS clients do not use UIDs and GIDs for identification. Since NAS server is intended
for working in a heterogeneous network, files created by non-NFS client could possess incorrect
ownership information and generate inaccurate quota information for UNIX/Linux clients due to the
unmatched UID and GID. A mapping is needed to maintain the correct identity of the user using
multiple protocols to access NAS server, for example Windows and UNIX/Linux clients. Windows
based clients need to map the Windows user name to UID/GID before forwarding a request to retain
the correct ownership information for UNIX/Linux clients. By default, the NAS server maps all
non-NFS users, including local users and domain users, with the same UID/GID as defined on this
page. If the administrator wants to have different UID/GID for different users, he should click the
Modify button to modify the user mapping to UID/GID.
UID: User ID. The numerical number assigned to a user in Unix/Linux permissions. NFS uses UID to
determine permissions on files and directories.
GID: Group ID. A part of POSIX permissions that determine groups of users. NFS files have a GID
assigned to them.
Permission: Three numbers are used for setting the file permission. Each of the three numbers
corresponds to the type of users- Owner, Members of a group and Everyone Else.

Configuring UNIX/Linux Network Settings
1. Click the Enable UNIX/Linux Network (NFS Protocol) checkbox to enable access for NFS client.
2. Enter the default permission for files created via non-NFS protocol. (Default setting = 755)
3. Click Apply to save the settings.
4. Click the Modify icon and enter the default UID and GID. (Default setting = 0)
5. Choose to map all users to the default UID/GID or assign UID/GID for each user manually.
6. Click Set Default link to set the UID/GID of all users to the default UID/GID. Note that the value ‘-1’
25
represent that the UID/GID is equal to the default UID/GID configured above.
7. Click Apply to save the settings
Configuring NIS settings
The NIS (network information services), formerly known as Yellow Pages, is a UNIX standard for
centralizing the management of UNIX resources. The NAS server supports the retrieval of user
accounts and their UID/GID from a NIS server.
If the NIS support is enabled, the NAS server can auto-map NIS users with local/domain users. It
matches user names and assigns the UID/GID of the matched NIS users to local/domain users. The
user auto-mapping function provides better and tighter integration between NFS clients and other
network operating systems.
The steps of enabling NIS support are as follows:
1. Check the Enable NIS Support checkbox.
2. The NIS domain name is required. Please fill in the correct name in NIS Domain Name field.
3. If you do not know the IP address of the NIS server, please specify Find by broadcast. Otherwise,
specify the IP address in the fields.
4. After enabling the NIS support, you can auto-mapping NIS users with local/domain users. In
UNIX/Linux menu, click the Modify icon.
5. Select Map users to UID/GID as defined below to Apply.
6. Click the Auto-map with NIS users link to map with the users in the configured NIS server.
