 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 "0.0.0.0".
(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.
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.
