In this chapter, the following topics are covered:

Service Binding
DDNS Service




(i) IP Address

Configure the TCP/IP settings, DNS Server and default Gateway of the NAS on this page.


Click the "Edit" button next to an interface under "Edit" to edit the network settings (including  "Network Parameters", "Advanced Options", and "DHCP Server".) For the NAS with two LAN ports, users can connect both network interfaces to two different switches and configure the TCP/IP settings. The NAS will acquire two IP addresses which allow access from two different subnets. This is known as multi-IP settings*. When using Qfinder to detect the NAS IP, the IP of Ethernet 1 will be shown in LAN 1 only and the IP of Ethernet 2 will be shown in LAN 2 only. To use port trunking for a dual LAN connection, see section (iii).


* TS-110, TS-119, TS-210, TS-219, TS-219P, TS-119P+, TS-219P+, TS-112, and TS-212 only have one LAN port and do not support dual LAN configuration or port trunking.


Network Parameters

Under "Network Parameters" on the TCP/IP Property page, configure the following settings:

Network Speed: Select the network transfer rate according to the network environment of the NAS. Select auto negotiation and the NAS will automatically adjust the transfer rate.
Obtain the IP address settings automatically via DHCP: If the network supports DHCP, select this option and the NAS will automatically obtain the IP address and network settings.
Use static IP address: To use a static IP address for network connections, enter the IP address, subnet mask, and default gateway.
Jumbo Frame: "Jumbo Frames" refers to Ethernet frames that are larger than 1500 bytes. It is designed to enhance Ethernet networking throughput and reduce the CPU utilization of large file transfers by enabling more efficient larger payloads per packet. Maximum Transmission Unit (MTU) refers to the size (in bytes) of the largest packet that a given layer of a communications protocol can transmit. The NAS uses standard Ethernet frames (1500 bytes) by default. If network appliances support Jumbo Frames, select the appropriate MTU value for the network environment. The NAS supports 4074, 7418, and 9000 bytes for MTU.



Jumbo Frames is only valid in Gigabit networks. All of the connected network appliances must enable Jumbo Frames and use the same MTU value.
Jumbo Frames are only supported by certain NAS models. Refer to the software specification page on the QNAP website for further details.


Advanced Options

A Virtual LAN (VLAN) is a group of hosts which communicate as if they were attached to the same broadcast domain even if they are located in different physical locations. The NAS can join a VLAN and be configured as a backup storage of other devices on the same VLAN.


To join a VLAN, select "Enable VLAN" and enter the VLAN ID (a value between 0 and 4094.) Keep the VLAN ID safe and make sure the client devices are able to join the VLAN. If you forget the VLAN ID and cannot connect to the NAS, you will need to reset the network settings by pressing the NAS reset button. Once the NAS is reset, the VLAN feature will be disabled. If the NAS supports two Gigabit LAN ports and only one network interface is configured to enable VLAN, you can also connect to the NAS via the other network interface.


Note: The VLAN feature is only supported by x86-based NAS models.


DHCP Server

A DHCP (Dynamic Host Configuration Protocol) server assigns IP addresses to clients on a network. Select "Enable DHCP Server" to set the NAS a DHCP server if there are none on the local network where the NAS is located.



Do not enable DHCP server if there is one on the local network to avoid IP address conflicts or network access errors.
The DHCP server option is only available to Ethernet 1 when both LAN ports of a dual LAN NAS are connected to the network and configured as standalone IP settings.


Start IP, End IP, Lease Time: Set the range of IP addresses allocated by the NAS to the DHCP clients and the lease time. The lease time refers to the time that an IP address is leased to the clients. During that time, the IP will be reserved to the assigned client. When the lease time expires, the IP can be assigned to another client.
WINS Server (optional): WINS (Windows Internet Naming Service) resolves Windows network computer names (NetBIOS names) to IP addresses, allowing Windows computers on a network to easily find and communicate with each other. Enter the IP address of the WINS server on the network if available.
DNS Suffix (optional): The DNS suffix is used for resolution of unqualified/incomplete host names.
TFTP Server & Boot File (optional): The NAS supports PXE booting of network devices. Enter the IP address of the TFTP server and the boot file (including directory on the TFTP server and file name.) For remote booting of devices, enter the public IP address of the TFTP server.


(ii) DNS Server

A DNS (Domain Name Service) server translates between a domain name (such as google.com) and an IP address ( Configure the NAS to obtain a DNS server address automatically or to specify the IP address of a DNS server.

Primary DNS Server: Enter the IP address of the primary DNS server.
Secondary DNS Server: Enter the IP address of the secondary DNS server.



Contact your ISP or network administrator for the IP address of the primary and the secondary DNS servers. When the NAS plays the role as a terminal and needs to perform independent connection (BT download, etc) enter at least one DNS server IP for proper URL connection. Otherwise, the function may not work properly.
If you obtain the IP address by DHCP, there is no need to configure the primary and secondary DNS servers. In this case, enter "".


(iii) Default Gateway

Select the gateway settings to use if both LAN ports have been connected to the network (dual LAN NAS models only.)


(iv) Port Trunking

The NAS supports port trunking which combines two Ethernet interfaces into one to increase bandwidth and offers load balancing and fault tolerance (also known as failover.) Load balancing is a feature which distributes workloads evenly across two Ethernet interfaces for higher redundancy. Failover is the capability to maintain high availability by switching to a standby network interface ("slave" interface) when the primary network interface ("master" interface) does not correspond correctly.


To use port trunking on the NAS, make sure at least two LAN ports of the NAS have been connected to the same switch and the settings described in sections (i) and (ii) have been configured.

Follow these steps to configure port trunking on the NAS:

1.Click "Port Trunking".
2.Select the network interfaces for a trunking group (Ethernet 1+2, Ethernet 3+4, Ethernet 5+6, or Ethernet 7+8.) Choose a port trunking mode from the drop-down menu. The default option is Active Backup (Failover.)
3.Select a port trunking group to use. Click "Apply".
4.Click "here" to connect to the login page.
5.Go to "Control Panel" > "System Settings"  > "Network"  > "TCP/IP".
6.Click the "Edit" button under "Edit" to edit the network settings.



Make sure the Ethernet interfaces are connected to the correct switch and the switch has been configured to support the port trunking mode selected on the NAS.
Port Trunking is only available for NAS models with two or more LAN ports.


The port trunking options available on the NAS:



Switch Required

Balance-rr (Round-Robin)

Round-Robin mode is good for general purpose load balancing between two Ethernet interfaces. This mode transmits packets in sequential order from the first available slave through the last. Balance-rr provides load balancing and fault tolerance.

Supports static trunking. Make sure static trunking is enabled on the switch.

Active Backup

Active Backup only uses one Ethernet interface. It switches to the second Ethernet interface if the first Ethernet interface does not work properly. Only one interface in the bond is active. The bond's MAC address is only visible externally on one port (network adapter) to avoid confusing the switch. Active Backup mode provides fault tolerance.

General switches

Balance XOR

Balance XOR balances traffic by splitting up outgoing packets between the Ethernet interfaces, using the same one for each specific destination when possible. It transmits based on the selected transmit hash policy. The default policy is a simple slave count operating on Layer 2 where the source MAC address is coupled with destination MAC address. Alternate transmit policies may be selected via the xmit_hash_policy option. Balance XOR mode provides load balancing and fault tolerance.

Supports static trunking. Make sure static trunking is enabled on the switch.


Broadcast sends traffic on both network interfaces. This mode provides fault tolerance.

Supports static trunking. Make sure static trunking is enabled on the switch.

IEEE 802.3ad (Dynamic Link Aggregation)

Dynamic Link Aggregation uses a complex algorithm to aggregate adapters by speed and duplex settings. It utilizes all slaves in the active aggregator according to the 802.3ad specification. Dynamic Link Aggregation mode provides load balancing and fault tolerance but requires a switch that supports IEEE 802.3ad with LACP mode properly configured.

Supports 802.3ad LACP

Balance-tlb (Adaptive Transmit Load Balancing)

Balance-tlb uses channel bonding that does not require any special switch. The outgoing traffic is distributed according to the current load on each Ethernet interface (computed relative to the speed.) Incoming traffic is received by the current Ethernet interface. If the receiving Ethernet interface fails, the other slave takes over the MAC address of the failed receiving slave. Balance-tlb mode provides load balancing and fault tolerance.

General switches

Balance-alb (Adaptive Load Balancing)

Balance-alb is similar to balance-tlb but also attempts to redistribute incoming (receive load balancing) for IPV4 traffic. This setup does not require any special switch support or configuration. The receive load balancing is achieved by ARP negotiation sent by the local system on their way out and overwrites the source hardware address with the unique hardware address of one of the Ethernet interfaces in the bond such that different peers use different hardware address for the server. This mode provides load balancing and fault tolerance.

General switches




To connect to a Wi-Fi network, plug a USB wireless dongle into the NAS. The NAS will detect a list of wireless access points. You can connect the NAS to a Wi-Fi network in two ways.



Wireless connection performance depends on many factors such as the adapter model, the USB adapter's performance, and the network environment. Wired connections will always provide greater stability and performance.
The system only supports one USB Wi-Fi dongle at a time.
For a list of compatible USB Wi-Fi dongles, visit http://www.qnap.com/compatibility and select "USB Wi-Fi".
This feature is not supported by the TS-269H.


Method 1: Connecting to an existing Wi-Fi network:

A list of Wi-Fi access points with signal strength are displayed in "Wi-Fi Network Connection".

Icon / Option





Search for Wi-Fi networks in range.

Secured network

The Wi-Fi network requires a network key.


Connect to a Wi-Fi network. If a security key is required, you will be prompted to enter the key.


Edit the connection information. You can select to automatically connect to the Wi-Fi network.


Disconnect from the Wi-Fi network.


Delete the Wi-Fi network profile.

Show all

Display all available Wi-Fi networks. Deselect this option to only show configured network profiles.


Click "Rescan" to search for available Wi-Fi networks. Select a Wi-Fi network to connect to and click "Connect". Enter the security key if needed. Click "Next" and the NAS will attempt to connect to the wireless network. You can view the status of the configured network profiles.




The NAS is currently connected to the Wi-Fi network.


The NAS is trying to connect to the Wi-Fi network.

Out of range or hidden SSID

The wireless signal is not available or the SSID is not broadcast.

Failed to get IP

The NAS is connected to the Wi-Fi network but could not get an IP address from the DHCP server. Check the router settings.

Association failed

The NAS cannot connect to the Wi-Fi network. Check the router settings.

Incorrect key

The entered security key is incorrect.

Auto connect

Automatically connect to the Wi-Fi network. This is not supported if the SSID of the Wi-Fi network is not broadcast.


Method 2: Manually connecting to a Wi-Fi network:

To manually connect to a Wi-Fi network that does not broadcast its SSID (network name), click "Connect to a Wi-Fi network".


You can choose to connect to an ad hoc network in which you can connect to any wireless devices without the need for an access point. To set up, follow these steps:

1.Enter the network name (SSID) of the wireless network and select the security type.
oNo authentication (Open): No security key required.
oWEP: Enter up to 4 WEP keys and choose 1 key to be used for authentication.
oWPA-Personal: Choose AES or TKIP encryption and enter the encryption key.
oWPA2-Personal: Enter a security key.
2.Type in the security key.
3.Click "Finish" after the NAS has added the Wi-Fi network.
4.To edit IP address settings, click "Edit". You can choose to automatically obtain the IP address by DHCP or to set a fixed IP address.


If the Wi-Fi connection is the only connection between the NAS and the router/AP, you must select "WLAN1" as the default gateway in "Network" > "TCP/IP" page. Otherwise, the NAS will be unable to connect to the Internet or communicate with another network.



The WEP key must be exactly 5 or 13 ASCII characters; or exactly 10 or 26 hexadecimal characters (0-9 and A-F.)
If you have trouble connecting to an encrypted wireless network, check the wireless router/AP settings and change the transfer rate from "N-only" mode to "B/G/N mixed" or similar settings.
Windows 7 users with WPA2 encryption cannot establish ad-hoc connection with the NAS. WEP encryption must be used on Windows 7.
A fixed IP address is required for wireless interfaces to establish an ad-hoc connection.




The NAS supports IPv6 connectivity with "stateless" address configurations and RADVD (Router Advertisement Daemon) for IPv6, RFC 2461 to allow the hosts on the same subnet to automatically acquire IPv6 addresses from the NAS . NAS services which support IPv6 include:

Web Server
QTS Desktop
Qsync for Windows
Netbak Replicator


To use this function, select the option "Enable IPv6" and click "Apply". The NAS will restart. After the system restarts, go to the IPv6 page. The settings of the IPv6 interface will be shown. Click the "Edit" button to edit the settings:

IPv6 Auto Configuration: If an IPv6 enabled router is available on the network, select this option to allow the NAS to automatically acquire the IPv6 address and configurations.
Use static IP address: To use a static IP address, enter the IP address (e.g. 2001:bc95:1234:5678), prefix length (e.g. 64), and the gateway address for the NAS. Contact your ISP for the prefix and the prefix length information.
oEnable Router Advertisement Daemon (radvd): To configure the NAS as an IPv6 host and distribute IPv6 addresses to the local clients which support IPv6, enable this option and enter the prefix and prefix length.
IPv6 DNS server: Enter the preferred DNS server in the upper field and the alternate DNS server in the lower field. Contact the ISP or network administrator for the information. If IPv6 auto configuration is selected, leave the fields as "::".


Service Binding


NAS services run on all available network interfaces by default. You can bind services to one or more specific network interfaces (wired or wireless). Available network interfaces on the NAS will be shown. Select at least one network interface that each service should be bound to. Then click "Apply". Users will only be able to connect to services via the specified network interfaces. If the settings cannot be applied, click "Refresh" to list the current network interfaces on the NAS and configure service binding again.



Service binding is only available for NAS models with multiple network interfaces (wired and wireless.)
After applying service binding settings, the connection of currently online users will be kept even if they were not connected to services via the specified network interfaces. The specified network interfaces will be used for the next connected session.




Enter the proxy server settings to allow the NAS to access the Internet through a proxy server to update the firmware, get new virus definitions, and to download Apps.


DDNS Service


To allow remote access to the NAS using a domain name instead of a dynamic IP address, enable the DDNS service.

The NAS supports the DDNS providers: http://www.dyndns.com, http://update.ods.org, http://www.dhs.org, http://www.dyns.cx, http://www.3322.org, http://www.no-ip.com, http://www.Selfhost.de, http://www.oray.com.


Note: Some of these DDNS services are not free.
