Network Setup
The MCU has installed two NIC (Network Interface Card) in system; it allows you could setup the
related network parameters for each NIC, and DNS server in this page.
¾ Eth0/Eth1
The MCU just support the static IP mode. Please enter in the IP address, subnet mask, gateway
address address(es) provided to you by your ISP. Each IP address entered in the fields must be in the
appropriate IP form, which are four IP octets separated by a dot (x.x.x.x). The Router will not accept the
IP address if it is not in this format.

¾ DNS
DNS stands for Domain Name System. Every Internet host must have a unique IP address; also they
may have a user-friendly, easy to remember name such as www.planet.com.tw. The DNS server
converts the user-friendly name into its equivalent IP address. The original DNS specifications require
that each domain name is served by at least 2 DNS servers for redundancy. When you run your DNS,
web, and mail servers all on the same MAChine - if this MAChine goes down, it doesn't really matter
that the backup DNS server still works.
The recommended practice is to configure the primary and secondary DNS servers on separate
MAChines, on separate Internet connections, and in separate geographic locations.
