(4) xDSL Interface
If WebEye is connected on xDSL line and needs PPPoE process, administrator should select ‘xDSL
(PPPoE)’ and configure ID and password for PPPoE. ID and password may be acquired from the
ISP that installed the line. And WebEye may get IP address when it is connected on xDSL line.
4) Dynamic IP registration service for ISDN and xDSL users
This page is to register WebEye on dynamic IP registration server.
If WebEye is installed on a
network of dynamic IP address
(floating IP address), administrator
should register the WebEye to
‘dynamic IP registration server’ to
give simple connectivity to
common users. If not, no one can
access the WebEye through Web
browser. It is because that no one knows with which IP address one can access the WebEye.
To solve the problem WebGate run a server making a list of WebEyes that have dynamic IP
addresses. On the server, WebEye registers its information such as name, location, and description,
so that common users may detect a certain WebEye. Name, location and description are assigned at
‘System Configuration’ page. If administrator does not change them, the WebEye will register
default information on the list, and it will be very difficult to point out and access a certain WebEye.
The list is on an Internet homepage of WebEye, ‘www.webeye.to’.
(1) Auto IP Registration Function
Administrator may register one’s WebEye by enabling ‘Auto IP Registration Function’.
Registration process is that WebEye detects IP addresses from DHCP server and informs the
detected IP addresses to dynamic IP registration server. And the server updates already registered
information with new one. Please keep in mind that user have to enable ‘DHCP Client Protocol’ at
‘Network Configuration’ page to have WebEye get dynamic IP addresses automatically, when
WebEye is installed on a network of dynamic IP address. With ‘Auto IP Registration Function’
menu, a WebEye of fixed IP address can also be registered on the list.
DNS (Domain Name System)
DNS (Domain Name System) is to map between IP
address and domain name. Every network
device on the world has its IP address to be connected on Internet. And the device is to be
connected not with its domain name but with its IP address. Common users are not familiar
with IP addresses but with domain names.
If a user accesses a certain network device with its domain name, DNS
server resolves the
domain name into an IP address of the device and replies the result to the user. A lot of DN
S
servers are run on Internet worldwide.
