Always on:

If you want the router to establish a PPPoE session when starting

up and to automatically re-establish the PPPoE session when disconnected by

the ISP.

•

Connect to Demand(PPPoE only):

If you want to establish a PPPoE session

only when there is a packet requesting access to the Internet (i.e. when a

program on your computer attempts to access the Internet).

•

Idle Timeout:

Auto-disconnect the broadband firewall gateway when there is no

activity on the line for a predetermined period of time.

•

RIP:

RIP v1, RIP v2, RIP v1+v2 and RIP v2 Multicast.

•

MTU:

Maximum Transmission Unit. The size of the largest datagram (excluding

media-specific headers) an IP attempts to send through the interface. Please use:

RFC 1483 Routing

•

Description:

Your description of this connection.

•

VPI and VCI:

Enter the information provided by your ISP.

•

NAT:

The NAT (Network Address Translation) feature allows multiple users to access

the Internet through a single IP account, sharing the single IP address. If users on

your LAN have public IP addresses and can access the Internet directly, the NAT

function can be disabled.

•

Encapsulation method:

Select the encapsulation format, the default is LLC Bridged.

Select the one provided by your ISP.

•

DHCP client:

Enable or disable the DHCP client, specify if the router can get an IP

address from the Internet Service Provider (ISP) automatically or not.

•

Obtain an IP address automatically via DHCP client

to enable the DHCP client

function or click Specify an IP address to disable the DHCP client function, and specify

the IP address manually. The setting of this item is specified by your ISP.

•

RIP:

RIP v1, RIP v2, RIP v1+v2 and RIP v2 Multicast.

3.6.3.2.2 DNS

A Domain Name System (DNS) contains a mapping table for domain name and IP addresses.

On the Internet, every host has a unique and user-friendly name (domain name) such as

www.yahoo.com and an IP address. An IP address is a 32-bit number in the form of

xxx.xxx.xxx.xxx

, for example 192.168.1.254. You can think of an IP address as a telephone

number for devices on the Internet, and the DNS allows you to find the telephone number for

any particular domain name. Since an IP Address is hard to remember, the DNS converts the

friendly name into its equivalent IP Address.

You can obtain a Domain Name System (DNS) IP address automatically if your ISP has

provided it when you logon. Usually when you choose PPPoE or PPPoA as your WAN - ISP

protocol, the ISP provides the DNS IP address automatically. You may leave the

configuration field blank. Alternatively, your ISP may provide you with an IP address of their

DNS. If this is the case, you must enter the DNS IP address.

If you choose one of the other protocols, RFC1483 Routed or Bridged,

check with your ISP, as it may provide you with an IP address for their DNS

server. You must enter the DNS IP address if you set the DNS Server

address on your PC to the LAN IP address of this router.

3.6.3.3 System

There are six items within the

System

section:

Time Zone, Remote Access, Firmware

Upgrade, Backup/Restore, Restart

and

User Management.

3.6.3.3.1 Time Zone

The router does not have a real time clock on board; instead, it uses the Simple Network

Time Protocol (SNTP) to get the current time from an SNTP server outside your network.

Choose your local time zone, click

Enable

and click the

Apply

button. After a successful

connection to the Internet, the router retrieves the correct local time from the SNTP server

you have specified. If you prefer to specify an SNTP server other than those in the drop-

down list, simply enter its IP address as shown above. Your ISP may provide an SNTP

server for you to use.

Resync Period

(in minutes) is the periodic interval the router waits before it resynchronizes

the router’s time with that of the specified SNTP server. To avoid unnecessarily increasing

the load on your specified SNTP server you should keep the poll interval as high as possible

at the absolute minimum every few hours or even days.

3.6.3.3.2 Remote Access

To temporarily permit remote administration of the router (i.e. from outside your LAN), select

a time period the router permits remote access for and click Enable. You may change other

configuration options for the web administration interface using Device Management options

in the

Advanced

section of the GUI.
