Subnet Mask Subnets allow network traffic between hosts to be separated based on

the network's configuration. In IP networking, traffic takes the form of

packets. IP subnets advance network security and performance to

some level by organizing hosts into logical groups. Subnet masks

contain four bytes and usually appear in the same "dotted decimal"

data. For example, a very common subnet mask in its binary

demonstration 11111111 11111111 11111111 00000000 will usually be

shown in the corresponding, more readable form as 255.255.255.0.

Gateway A gateway is a piece of software or hardware that passes information

between networks. You'll see this term most often when you either log

in to an Internet site or when you're transient email between different

servers.

Obtain DNS from

DHCP

Enable this checked box when a DHCP server is installed on the

network and provide DNS service.

Primary DNS When you send email or position a browser to an Internet domain such

as xxxxx.com, the domain name system translates the names into IP

addresses. The term refers to two things: the conventions for naming

hosts and the way the names are control across the Internet.

Secondary DNS The same function as DNS1. It is option not necessary

HTTP Port The device supports two HTTP ports. The first one is default port 80

and this port is fixed. This port is very useful for Intranet usage. The

second HTTP port is changeable. Users could assign the second port

number of http protocol, and the WAN users should follow the port

number to login. If the http port is not assigned as 80, users have to

add the port number in back of IP address. For example:

http://192.168.0.20:8080.

Therefore, the user can access the device by either

http://xx.xx.xx.xx/, or

http://xx.xx.xx.xx:xxxx/ to access the device.

If multiple devices are installed on the LAN and also required to be

accessed from the WAN, then the HTTP Port can be assigned as the

virtual server port mapping to support multiple devices.

NOTE When the configuration is finish, please click “OK” to save and enable

the setting.
