of the router, which is assigned to you by your ISP.

You first need to register and establish an account with the Dynamic DNS provider using

their website, for example http://www.dyndns.org/

There are more than 5 DDNS services supported.

Disable:

Check to disable the Dynamic DNS function.

Enable:

Check to enable the Dynamic DNS function. The fields following are activated

and required.

Dynamic DNS Server:

Select the DDNS service you have established an account with.

Host:

Enter one domain name you have registered.

Domain Name, Username and Password:

Enter your registered domain name and

your username and password for this service.

Period:

Set the time period between updates, for the router to exchange information with

the DDNS server. In addition to updating periodically as per your settings, the router

performs an update when your dynamic IP address changes.

Wildcard:

Select this check box to enable the DYNDNS Wildcard.

4.3.7.3 Vlan Control

VLAN (Virtual Local Area Network) is a group of devices on different physical LAN segments

that can communicate with each other as if they were all on the same physical LAN

segment.

4.3.7.4 Device Management

The Device Management advanced configuration settings allow you to control your router’s

security options and device monitoring features.

Embedded Web Server:

HTTP Port:

The port number of the router’s embedded web server (for web-based

configuration uses. The default value is the standard HTTP port, 80. You may specify an

81

alternative if, for example, you are running a web server on a PC within your LAN.

For Example:

User A changes HTTP port number to

100

, specifies their own IP address of

192.168.0.55

, and sets the logout time to be

100

seconds.

The router only allows User A

access from the IP address

192.168.0.55

to logon to the Web GUI by typing:

http://

192.168.0.254.100

in their web browser. After 100 seconds, the device automatically

logs out User A.

Universal Plug and Play (UPnP):

UPnP offers peer-to-peer network connectivity for PCs and other network devices, along

with control and data transfer between devices. UPnP offers many advantages for users

running NAT routers through UPnP NAT Traversal, and on supported systems makes tasks

such as port forwarding much easier by letting the application control the required settings,

removing the need for the user to control advanced configuration of their device.

Both the user’s Operating System and the relevant application must support UPnP in

addition to the router. Windows XP and Windows Me natively support UPnP (when the

component is installed), and Windows 98 users may install the Internet Connection Sharing

client from Windows XP in order to support UPnP. Windows 2000 does not support UPnP.

~

Disable:

Check to disable the router’s UPnP functionality.

~

Enable:

Check to enable the router’s UPnP functionality.

UPnP Port:

The default setting is 2800. It is highly recommended that you use this port

value. If the value conflicts with other ports already in use you may wish to change the port.

SNMP Access Control

Simple Network Management Protocol—software on a PC within the LAN is required to use

this function.

SNMP V1 and V2:

Read Community:

Specify a name to be identified as the Read Community, and an IP

address.

This community string is checked against the string entered in the configuration

file. Once the string name is matched, you can obtain this IP address and are able to view

the data.

Write Community:

Specify a name to be identified as the Write Community, and an IP

address. This community string is checked against the string entered in the configuration file.

Once a string name is matched, users from this IP address are able to view and modify data.

Trap Community:

Specify a name and an IP address. This community string is checked

82

against the string entered in the configuration file. Once a string name is matched, users

from this IP address are sent SNMP Traps.

SNMP V3:

Specify a name and password for authentication, and define access rights from the identified

IP address. Once authentication has succeeded, users from this IP address are able to view

and modify data.

SNMP Version: SNMPv2c and SNMPv3

SNMPv2c is the combination of the enhanced protocol features of SNMPv2 without the

SNMPv2 security. The "c" comes from the fact that SNMPv2c uses the SNMPv1 community

string paradigm for "security" but is widely accepted as the SNMPv2 standard.

SNMPv3 is a strong authentication mechanism with fine granularity for remote monitoring.

Traps supported: Cold Start, Authentication Failure.
