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 (74.125.31.105.) 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.
Note :
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".
