can connect the network interfaces to different switches and configure the TCP/IP 
settings. The NAS will acquire an IP address for each connected interface, which can 
access a subnet for each IP. This is known as multi-IP settings*. When using Qfinder 
Pro to detect the NAS IP, the IP of Ethernet 1 will only be shown in LAN 1 and the IP 
of Ethernet 2 will only be shown in LAN 2, etc. You can choose to use port trunking for 
multiple LAN connections.

DNS Server 
A DNS (Domain Name System) server translates between a domain name (such as 
google.com) and an IP address (74.125.31.105). On this page, you can configure the NAS to 
obtain a DNS server address automatically or to specify the IP address of a DNS server. If 
you choose to specify the IP address, fill out the following fields:  
o Primary DNS Server: Enter the IP address of the primary DNS server. 
o Secondary DNS Server: Enter the IP address of the secondary DNS server.

Note: 
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 and certain 
models only provide one Giga LAN port and therefore do not support dual LAN 
configuration or Port Trunking. 
 
The Port Trunking options available on the NAS:

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.

USB QuickAccess 
USB QuickAccess allows users to directly connect their NAS to their computer using a USB 
cable and Common Internet File System (CIFS) for using the NAS as a USB storage device. 
You can perform the following operations using this feature:  
Turn on/off USB QuickAccess: Click the switch icon (to the left of the USB QuickAccess 
Port icon) to enable/disable USB QuickAccess.    
Choose between DHCP and a static IP address: Click the Configure icon and choose 
whether to obtain...

Note: 
Wireless connection performance depends on many factors such as the adapter model, 
the USB adapters 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.

Setting up the TBS-453A 
The TBS-453A is the only QNAP NAS model with a built-in physical switch chip for optimized 
switch performance. For this model, you can connect the network interfaces 2-1~2-4 to a 
physical switch for network expansion. This model also has two modes: Switch mode and 
Private Network mode. To set up Switch mode, follow these steps: 
1. Connect one of the four ports (Port 2-1 to 2-4) to an external network or a default 
gateway and connect your local devices to any of the...
