that a network can transmit. Any messages larger than the MTU are divided into smaller packets before
being sent. The network MTU rate is set to 1500 bytes with default settings.
¾ MRU
MRU stands for Maximum Receiving Unit. the largest physical packet size, measured in bytes that a
network can receive. Any messages larger than the MRU are divided into smaller packets before being

¾ Set DNS Server
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.xxx.com. 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.
 Primary DNS Server: Sets the IP address of the primary DNS server.
 Secondary DNS Server: Sets the IP address of the secondary DNS server.
There are two methods to set the DNS server:
a. Automatically (Default setting)
When you select the Auto mode, the IP address of DNS server will be gotten from ISP’s DHCP
server. You will get IP address of the primary DNS server and the secondary DNS server.
b. Manually
When you want to set the DNS server manually, you can select this mode to set primary DNS server
and secondary DNS server as below.
Field Description Default value
Primary DNS Server Sets the IP address of the primary DNS server 168.95.1.1
Secondary DNS Server Sets the IP address of the secondary DNS server 168.95.192.1
