DHCP Server

You can disable or enable the DHCP (Dynamic Host Configuration Protocol) server or enable the router’s DHCP relay

functions. The DHCP protocol allows your router to dynamically assign IP addresses to the PCs on your network if they

are configured to obtain IP addresses automatically.

To disable the router DHCP Server, check Disabled and click Next, then click Apply. When the DHCP Server is

disabled you will need to manually assign a fixed IP address to each PC on your network, and set the default gateway

for each PC to the IP address of the router (by default this is 10.0.0.2).

To configure the router DHCP Server, check DHCP Server and click next. You can then configure parameters of the

DHCP Server including the IP pool (starting IP address and ending IP address to be allocated to PCs on your network),

lease time for each assigned IP address (the period of time the IP address assigned will be valid), DNS IP address and

the gateway IP address. These details are sent to the DHCP client (i.e. your PC) when it requests an IP address from

the DHCP server. Click Apply to enable this function. If you check Use Router as a DNS Server”, the ADSL Router will

perform the domain name lookup, find the IP address from the outside network automatically and forward it back to the

requesting PC in the LAN (your Local Area Network).

If you check DHCP Relay Agent and click Next, then you will have to enter the IP address of the DHCP server which

will assign an IP address back to the DHCP client in the LAN. Use this function only if advised to do so by your network

administrator or ISP.

Click Apply to enable this function.

WAN - Wide Area Network

WAN refers to your Wide Area Network connection, i.e. your router’s connection to your ISP and the Internet. Here

are the items within the WAN section:

WAN Interface, WAN Profile

and

ADSL Mode.

WAN Interface

WAN Connection-ADSL Mode

The default setting for Connection Mode is ADSL and the default Protocol is PPPoE.

Main Port:

User can select either ADSL, 3G mode or Dual WAN.

Mode:

Select the radio button if you want to enable the ADLS / 3G failover / failback function.

WAN1:

Select the primary WAN Interface it should use. You may select ADSL or 3G.

WAN2:

Select the secondary or failover WAN interface. i.e. If your primary connection fails, the secondary connection

will start up and connect to the internet automatically.

Time Schedule:

Select the time schedule when failover should be active. Always on is the default value.

Keep Backup Interface Connected:

Keeps the backup interface connected to allow seamless changeover when your

primary interface fails.

Connectivity Decision:

Set how many times probing must fail in order to switch to the backup port.

Failover Probe Cycle:

Set the duration for the Failover Probe Cycle to determine when the router will switch to the

backup connection (backup port) once the main connection (main port) fails.

Note: The time set is for each probe cycle, but the decision to change to backup port is determined by the

Probe Cycle duration multiplied by the connection Decision amount (e.g. From the image above it will be 12

seconds multiplied by 5 consecutive fails).

Failback Probe Cycle:

Set the duration for the Failback Probe Cycle to determine when the router will switch back to

the main connection (main port) from the backup connection (backup port) once the main connection is communicating

again.

Note: The time set is for each probe cycle, but the decision to change to the backup port is determined by the

Probe Cycle duration multiplied by the Connection Decision amount (e.g. From the image above it will be 3

seconds multiplied by 5 consecutive fails).

Detect Rule:

Rule 1. ADSL Down

Rule 2. Ping Fail

No Ping:

It will not send any ping packets to determine if the connection is active. It disables ping detection.

Ping Gateway:

It will send ping packets to the gateway and wait for a response from the gateway in every

“Probe Cycle”.

Ping Host:

It will send ping packets to a specific host and wait for a response in every “Probe Cycle”. The host

must be an IP address.

WAN Connection-3G Mode

In ADSL mode, as the ADSL is not available (failover/failback), it will switch to 3G mode for WAN Connection support.

However, in 3G Mode ADSL cannot support WAN Connection when 3G Mode is unavailable.

WAN Profile

PPPoE Connection

PPPoE (PPP over Ethernet) provides access control in a manner which is similar to dial-up services using PPP.

Profile Port:

Select the profile port as ADSL.

Protocol:

The PPPoE protocol will be used.

Description:

A given name for the connection.

VPI/VCI:

Enter the information provided by your ISP.

ATM Class:

The Quality of Service for ATM layer.

Username:

Enter the username provided by your ISP. You can input up to 128 alpha-numeric characters (case

sensitive). This is the format of username “username@ispname” instead of “username”.

Password:

Enter the password provided by your ISP. You can input up to 128 alpha-numeric characters (case

sensitive).

Service Name:

This item is for identification purposes. If it is required, your ISP will provide you the information.

Maximum input is 15 alpha-numeric characters.

NAT:

The NAT (Network Address Translation) feature allows multiple users to access the Internet through a single ISP

account, sharing a single IP address. If users on your LAN have public IP addresses and can access the Internet

directly, the NAT function can be disabled.

IP (0.0.0.0: Auto):

Your WAN IP address. Leave this at 0.0.0.0 to obtain an IP address automatically from your ISP.

Auth. Protocol:

Default is Auto. Your ISP should advise you on whether to use Chap or Pap.

Connection:

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 on Demand:

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.

MTU:

Maximum Transmission Unit. The size of the largest datagram, excluding media-specific headers, that IP will

attempt to send through the interface.

RIP:

RIP v1, RIP v2, and RIP v2 Multicast. Check to enable RIP function.

TCP MSS Clamp:

This option enables discovery of the optimal MTU size automatically. Default is enabled.

MAC Spoofing:

Some service providers require the configuration of this option. You must fill in the MAC address that

is specified by the service provider when it is required. Default is disabled.

Obtain DNS:

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

helps to find the IP address of a specific domain name. Check the checkbox to obtain DNS automatically.

Primary DNS:

Enter the primary DNS.

Secondary DNS:

Enter the secondary DNS.
