Chapter 4- Setting Up the ADSL Router
This section will guide you through your ADSL Router’s configuration. The ADSL Router is
shipped with a standard PPP configuration.
The basic tabs consist of features which are catered for basic users.
3.3 Logging into your ADSL Router
To configure your ADSL Router, open your web browser. You may get an error message at this
point; this is normal. Type the default IP address (192.168.1.1) or login.router on the web
address bar.
NOTE: Before setting up your ADSL Router, make sure you have followed the
easy start guide. You should have your computers configured for DHCP
mode and have proxies disabled on your browser. Upon accessing the
ADSL Router, if the browser still displays a login redirection screen, you
should check your browser's setting and ensure that the JavaScript support
is enabled. If the screen shown in Fig 1-4 is not attainable, you must
delete your temporary Internet files to clear the web cache.
Upon entering the default IP address or the short-cut name (login.router), if the user is logging
for the first time, the user will be brought to the “Quick Start” page. See Fig 1.4. The Quick Start
page is meant for basic users whom only require easy connectivity to the Internet without
worrying about any other advance configuration setting. If you are in doubt for what content to
enter for the Protocol, VPI and VCI, please contact your Service Provider for assistance.
Figure 1-4 : Quick Start
Page 12 of 42
ADSL2+ Ethernet USB Combo Router - User Guide
For those who have their routers configured, you will be directed to the “Basic Home” page.
See Fig 1-5.
Figure 1-5 : Basic Home
3.4 Quick Start
If you have already configured your router and wish to change your current configuration, click
on the ‘Quick Start’ link. Fig 1-6 will appear.
Figure 1-6 : Quick Start Page
Page 13 of 42
ADSL2+ Ethernet USB Combo Router - User Guide
3.5 LAN / DHCP Configuration
On one side of your ADSL Router, you have your own Local Area network (LAN) connections.
This is where you plug in your local computers to the ADSL Router. The ADSL Router is
normally configured to automatically provide all the PC's on your network with Internet
addresses.
To enable or disable DHCP, Click setup. Under LAN Setup, select DHCP Configuration. The
Start IP Address is where the DHCP server starts issuing IP addresses. This value must be
greater than the ADSL Router IP address value. For example if the ADSL Router IP address is
192.168.1.1 (default) than the starting IP address must be 192.168.1. 2 (or higher).
The End IP Address is where the DHCP server stops issuing IP addresses. The ending address
cannot exceed a subnet limit of 254. Hence the max value for our default gateway is
192.168.1.254. If the DHCP server runs out of DHCP addresses, users will not get access to
network resources. If this happens you can increase the Ending IP address (to the limit of 255)
or reduce the lease time.
The Lease Time is the amount of time a network user will be allowed connection to the ADSL
Router with their current dynamic IP address. The amount of time is in units of minutes; the
default value is 3600 minutes (60 hours).
Note: If you change the start or end values, make sure the values are still within the same subnet
as the gateways IP address. In other words, if the gateways IP address is 192.168.1.1 (default)
and you change the DHCP start/end IP addresses to be 192.128.1.2/192.128.1.100, you will not
be able to communicate to the ADSL Router if your PC has DHCP enabled.
In addition to the DHCP server feature, the ADSL Router supports the DHCP relay function.
When the ADSL Router is configured as DHCP server, it assigns the IP addresses to the LAN
clients. When the ADSL Router is configured as DHCP relay, it is responsible for forwarding the
requests and responses negotiating between the DHCP clients and the server.
By turning off the DHCP server and relay the network administrator must carefully configure the
IP address, Subnet Mask and DNS settings of every computer on your network. Do not assign
the same IP address to more than one computer and your ADSL Router must be on the same
subnet as all the other computers. See
Fig 1-7.

ADSL2+ Ethernet USB Combo Router - User Guide
3.6.1 Ping Test
Once you have your ADSL Router configured, ensure you can ping the network. Type the
target address that you want to ping. If your PC is connected to the ADSL Router via the default
DHCP configuration, you should be able to Ping the network address 192.168.1.1. See
Fig 1-10.
If your ISP has provided their server address, try to ping the address. If the pings for both the
WAN and the LAN sides are complete and you have the proper protocols configured, you should
be able to surf the Internet. By default when you select ping test, the ADSL Router will ping
itself 3 times. The ADSL Router passed the Ping test; this basically means that the TCP/IP
protocol is up and running. If the first Ping test does not pass, the TCP/IP protocol is not loaded
for some reason; you should restart the ADSL Router.
Figure 1-10 : Ping Test Screen
3.6.2 Modem Test
This test can be used to check whether your Modem is properly connected to the Network. Select
your connection from the list and press the
Figure 1-11 : Modem Test
‘Test’ button. See Fig 1-11.

3.7 Advanced
This mode is catered for advance users, a brief explanation of the links are listed as shown
below. See
Fig 1-12.
Figure 1-12 : Advanced Screen
3.7.1 WAN Connection
The Wide Area Network (WAN) connection exists on the other side of the ADSL Route, also
referred to as a broadband connection. This WAN connection is different for every WAN
supplier. Most of the configuration you will perform will be for WAN connection.
Page 18 of 42
ADSL2+ Ethernet USB Combo Router - User Guide
3.7.2 New Connection
A new connection is a virtual connection. Your ADSL Router can support up to 8 different
(unique) virtual connections. If you have multiple different virtual connections, you may need to
utilize the static and dynamic routing capabilities of the modem to pass data correctly.
Figure 1-13 : New Connection (PPPOE Connection Setup)
3.7.3 ADSL Modulation
To configure the DSL modulation type, Click WAN, ADSL Modulation. This will bring up the
modem setup screen. Leave the default value if you are unsure or the DSL/ISP did not provide
this information. In most cases, this screen should not be modified.
Figure 1-14 : ADSL Modulation (Modem Setup)
Page 19 of 42
ADSL2+ Ethernet USB Combo Router - User Guide
3.7.4 Quickstart
PPPoE is also known as RFC 2516. It is a method of encapsulating PPP packets over Ethernet.
PPP or Point-to-Point protocol is a method of establishing a network connection/session between
network hosts. It usually provides a mechanism of authenticating users.
To configure the gateway for PPPoE, click on Setup and then click on New Connection. The
default PPPoE connection setup is displayed. At the Type field select PPPoE and the PPPoE
connection setup page is displayed. Give your PPPoE connection a unique name; the name must
not have spaces and cannot begin with numbers. In this case the unique name is called quickstart.
Select the encapsulation type (LLC or VC); if you are not sure just use the default mode. Select
the VPI and VCI settings; your DSL service provider or your ISP will supply these. In this case
the DSL service provider is using 0, 100. Also select the quality of service (QoS); leave the
default value if you are unsure or the ISP did not provide this information. See
Fig 1-15.
Following is a description of the different options:
1. Username: The username for the PPPoE access; this is provided by your DSL service
provider or your ISP.
2. Password: The password for the PPPoE access; this is provided by your DSL service
provider or your ISP.
3. On-Demand: Enables on-demand mode. The connection will disconnect if no activity is
detected after the specified idle timeout value.
4. Idle Timeout: Specifies that PPPoE connection should disconnect if the link has no activity
detected for n seconds. This field is used in conjunction with the On-Demand feature. To
ensure that the link is always active, enter a 0 in this field.
5. Keep Alive: When on-demand option is not enable, this value specifies the time to wait
without being connected to your provider before terminating the connection. To ensure that
the link is always active, enter a 0 in this field.
6. Enforce MTU: Check this box if you experience problems accessing the Internet over a
PPPoE connection. This feature will force all TCP traffic to conform with PPP MTU by
changing TCP Maximum Segment Size to PPP MTU.

3.7.5 LAN Configuration
You can change the ADSL Router’s IP address by, clicking LAN, and then LAN Configuration.
Select the options from LAN group 1 and click Configure.
Your ADSL Router’s default IP address and subnet mask are 192.168.1.1/255.255.255.0; this
subnet mask will allow the ADSL Router to support 254 users. If you want to support a larger
number of users you can change the subnet mask; but remember that the DHCP server is
defaulted to only give out 255 IP addresses. Further remember that if you change your gateways’
IP address and you have DHCP enabled, the DHCP configuration must reside within the same
subnet. The default gateway is the routing device used to forward all traffic that is not addressed
to a station within the local subnet. Your ISP will provide you with the default gateway Address.
The hostname can be any alphanumeric word that does not contain spaces. The domain name is
used to in conjunction with the host name to uniquely identify the gateway. To access the ADSL
Router’s web pages, the user can type 192.168.1.1 (the default IP address) or type
mygateway.ar7. The apply button will temporarily save this connection. To make the change
permanent you need to click on Save Settings (at the side of the page).
Fig 1-16.

ADSL2+ Ethernet USB Combo Router - User Guide
3.7.6 LAN Clients
To add a LAN client, select LAN clients option under LAN. If DHCP was enabled in the
configuration, all DHCP clients are automatically assigned with IP address. If a fixed IP address
server is on the LAN and you want this server to be visible via the WAN, you must add its IP
address. Once the IP address has been added, you can apply Port Forwarding and Access Control
rules to this IP address.
Figure 1-17 : LAN Clients
Page 23 of 42
ADSL2+ Ethernet USB Combo Router - User Guide
3.7.7 Application (UPnP)
UPnP, NAT and Firewall Traversal allow traffic to pass-thru the ADSL Router for applications
using the UPnP protocol. This feature requires one active DSL connection. In presence of
multiple DSL connections, select the one over, which the incoming traffic will be present, for
example the default Internet connection.
To enable UPnP, you must first have a WAN connection configured. Once a WAN connection is
configured, click Advanced and under Application, select UPnP. You must enable UPnP and
then select which connection will utilize UPnP. See
Fig 1-18.

ADSL2+ Ethernet USB Combo Router - User Guide
3.7.8 SNTP
SNTP (Simple Network Timing Protocol) is a protocol used to synchronize the system time to
the public SNTP servers. When the SNTP feature is enabled, your DSL800EU will start
querying for the time clock information from the primary SNTP server. If it fails to get a valid
response within the “timeout” period, it will try for “retry” number of times, before moving to
the Secondary SNTP server. If it fails to get a valid response from Secondary STNP server
within valid retry times, it starts querying Tertiary SNTP server. If it fails to get a valid response
from all the servers, then the program stops. When a valid response is received from one of the
server, the program sleeps for “Polling_interval” amount of minutes, before starting the whole
process again. Use the following procedures to enable SNTP.
Use the following procedures to enable SNTP.
1. Check Enable SNTP.
2. Primary SNTP Server - The IP address or the host name of the primary SNTP server.
3. Secondary SNTP Server - The IP address or the host name of the secondary SNTP server.
4. Tertiary SNTP Server - The IP address or the host name of the tertiary SNTP server.
5. Timeout - If the DSL800EU failed to connect to a SNTP server within the ‘Timeout’
period, it will retry the connection.
6. Polling Interval - Time between a successful connection with a SNTP server and a new
attempt to connect to an SNTP server.
7. Retry Count - The number of times the DSL800EU will try to connect to an SNTP server
before it try to connect to the next server in line.
8. Time Zone - The time zone of the DSL800EU.
9. Day Light - Check/uncheck this option to enable/disable day light saving. See
Fig 1-19.

3.7.9 SNMP
SNMP (Simple Network Management Protocol) is a troubleshooting and management protocol,
which uses the UDP protocol on port 161 to communicate between clients and servers. SNMP
uses a manager MIB (management information base) agent solution to fulfill the network
management needs. The agent is a separate station that can request data from an SNMP agent in
each of the different managed system in the network. The agent uses the MIBs as dictionaries of
manageable objects. Each SNMP-managed device has at least one agent that can respond to the
queries from the NMS. The SNMP agent supports GETS, SETS, and TRAPS for 4 groups with
MIB-II: System, Interface, IP, and ICMP. The SNMP agent supports three-community names
authentication. See
Fig 1-20.

ADSL2+ Ethernet USB Combo Router - User Guide
3.7.10 IP QoS
When QoS is enabled in the AR7, the designated machine, application or person would have
precedence over peers when competing for bandwidth. The IP QoS Setup page allows you to
configure QoS for a connection, view previously configured QoS rules, add a new rule, or delete
an existing rule. Each output device has three priority queues associated with transmit data. The
high priority queues have strict priority over the medium priority and low priority queues, and
therefore can exhaust all available bandwidth. The web UI will allow the user to select the
weights of the medium and low priority queues in increments of 10 percent so that that the sum
of the weights of the 2 queues is equal to 100 percent. These queues will be serviced on a Round
Robin priority basis according to the weights assigned, after the high priority queues have been
completely serviced. See
Fig 1-21.

ADSL2+ Ethernet USB Combo Router - User Guide
3.7.11 IGMP Multicast
Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender to 1
recipient) or Broadcast (1 sender to everybody on the network). Multicast delivers IP packets to
just a group of hosts on the network. IGMP (Internet Group Multicast Protocol) is a session-layer
(layer-3) protocol used to establish membership in a Multicast group. It can register a router to
receive specific multicast traffic.
To enable Multicast, select the option Enable IGMP Multicast button and select the available
connection. See
Fig 1-22.
Figure 1-22 : IGMP Multicast

ADSL2+ Ethernet USB Combo Router - User Guide
3.7.12 Port Forwarding
Using the Port Forwarding page, you can provide local services (for example web hosting) for
people on the Internet or play Internet games. When users send this type of request to your
network via the Internet, the ADSL Router will forward those requests to the appropriate PC.
Port forwarding can be used with DHCP assigned addresses but remember that a DHCP address
is dynamic (not static). For example, if you were configuring a Netmeeting server, you would
want to assign this server a static IP address so that the IP address is not reassigned. Also
remember that if an Internet user is trying to access an Internet application, they must use the
WAN IP address. The port forwarding will translate the WAN IP address into a LAN IP address.
To configure a service, game, or other application select the external connection (for example the
Internet connection), from the Home screen, click Advanced and under Application, select Port
Forwarding. Next select the computer hosting the service and add the corresponding firewall
rule. If you want to add a custom application, select the User category, click New and fill in the
Rule Name, Protocol and Port number for your application.
For example, if you want to host a Netmeeting session, from the Home screen, click Advanced
and under Application, select Port Forwarding. First select the IP address for your Netmeeting
server. Next select the Audio/Video category and add Netmeeting to the applied rules box. To
view the management rules, highlight Netmeeting and select view; this will display the pre
configured protocols and ports that Netmeeting will use. Now assuming that your WAN
connection is correct, you can run Netmeeting from your server and call users that are on the
Internet. If you know your WAN IP address, users can call you. See
Fig 1-23

3.7.13 MAC Filtering (Bridge Filters)
The bridge filtering mechanism provides a way for the users to define rules to allow/deny frames
through the bridge based on source MAC address, destination MAC address and/or frame type.
When bridge filtering is enabled, each frame is examined against each defined filter rules
sequentially. When a match is determined, the appropriate filtering action (determined by the
access type selected i.e. allow or deny) is performed. Please note that the bridge filter will only
examine frames from interfaces, which are part of the bridge itself. Twenty filter rules are
supported with bridge filtering. See
Fig 1-24.

3.7.15 Routing (Static Routing)
If the ADSL Router is connected to more than one network, you may need to set up a static route
between them. A static route is a pre-defined pathway that network information must travel to
reach a specific host or network. You can use static routing to allow different IP domain users to
access the Internet through the ADSL Router.
The New Destination IP is the address of the remote LAN network or host to which you want to
assign a static route. Enter the IP address of the host for which you wish to create a static route
here. For a standard Class C IP domain, the network address is the first three fields of the New
Destination IP, while the last field should be 0. The Subnet Mask identifies which portion of an
IP address is the network portion, and which portion is the host portion. For a full Class C
Subnet, the Subnet Mask is 255.255.255.0. The Gateway IP address should be the IP address of
the gateway device that allows for contact between the Gateway and the remote network or host.

3.7.16 Dynamic Routing
Dynamic Routing allows the ADSL Router to automatically adjust to physical changes in the
network. The ADSL Router, using the RIP protocol, determines the network packets’ route
based on the fewest number of hops between the source and the destination. The RIP protocol
regularly broadcasts routing information to other ADSL Routers on the network. The Direction
determines the direction that RIP routes will be updated. Selecting
Router will only incorporate received RIP information. Selecting
Router will only send out RIP information. Selecting
Both means that the ADSL Router will
In means that the ADSL
Out means that the ADSL
incorporate received RIP information and send out updated RIP information.
The protocol is dependent upon the entire network. Most networks support RIP v1. If RIP v1 is
selected, routing data will be sent in RIP v1 format. If RIP v2 is selected, routing data will be
sent in RIP v2 format using subnet broadcasting. If RIP v1 Compatible is selected, routing data
will be sent in RIP v2 format using multicasting. See
Fig 1-27.
