4.5.3

SNMP

The

Simple Network Management Protocol (SNMP)

is used for exchanging information

between network devices. It enables a host computer to access configuration, performance,

and other system data that resides in a database on the modem. The host computer is called a

management station

and the modem is called an

SNMP agent

. The data that can be accessed

via SNMP is stored in a

Management Information Database

(MIB) on the modem.

Get Community:

Select to set the password for incoming Get- and GetNext request from

management station.

Set Community:

Select to set the password for incoming Set request from management

station.

4.5.4

UPnP

UPnP (Universal Plug and Play)

is a distributed, open networking standard that uses

TCP/IP for simple peer-to-peer network connectivity between devices. An UPnP device can

dynamically join a network, obtain an IP address, convey its capabilities and learn about other

devices on the network. In turn, a device can leave a network smoothly an automatically when

it is no longer in use. UPnP broadcasts are only allowed on the LAN.

UPnP (Universal Plug and Play):

You can choose

“Activated”

or

“Deactivated”

option from

this session.

63

Auto-Configured (by UPnP Application):

UPnP network devices can automatically

configure network addressing, announce their presence in the network to other UPnP devices

and enable exchange of simple product and service descriptions. Choose

“Activated”

option

to allow UPnP-enabled applications to automatically configure the ADSL Router so that they

can communicate through the ADSL Router, for example by using NAT traversal, UPnP

Page 65 / 80

applications automatically reserve a NAT forwarding port in order to communicate with another

UPnP enabled device; this eliminates the need to manually configure port forwarding for the

UPP enabled application.

If you don’t want to make configuration changes through UPnP,

just choose

“Deactivated”

.

SAVE

: Click

SAVE

to save the setting to the ADSL Router.

4.5.5

DDNS

64

The

Dynamic Domain Name System

allows you to update your current dynamic IP address

with one or many dynamic DNS services so that anyone can contact you (in NetMeeting,

CU-SeeMe, etc.). You can also access your FTP server or Web site on your own computer

using a DNS-like address (for instance myhost.dhs.org, where my host is a name of your

choice) that will never change instead of using an IP address that changes each time you

reconnect. Your friends or relatives will always be able to call you even if they don't know your

IP address. First of all, you need to have registered a dynamic DNS account with

www.dyndns.org. This is for people with a dynamic IP from their ISP or DHCP server that

would still like to have a DNS name. The Dynamic DNS service provider will give you a

password or key.
