ADSL Router Quick Set-up Guide  
Choose from your connection options:  
1. Ethernet (for standalone computer or multiple computers, Operating  
System independent)  
The router comes with a built-in 4-port network switch. Up to 4 computers  
can be connected to the router directly. If you require more connections to  
more computers, purchase another network hub and connect it to the router  
to provide for more connections. Only one Ethernet cable is provided. Extra  
cables and network hub can be purchased from your supplier.  
2. USB (for standalone Windows 98/ME/2000/XP computers only)  
If one of your computers does not have an Ethernet port you may choose this  
option. You must then install a driver to operate the router. The drivers are  
found on this CD. To install a driver into Windows, go to the previous menu  
and click the Modem drivers button.  
Connect the Router  
1. Connect the DSL port of the router directly into your ADSL jackpoint (telephone  
wall socket) with the provided line cord. Do not connect through a filter, unless  
the filter has a designated MODEM port for this purpose.  
3
2. Connect the Ethernet port of each computer to any one of the LAN ports of  
the router. Only one Ethernet cable is provided. If you choose to connect via  
the USB port, make no USB connection now. During driver installation, you  
will be advised to connect the USB port of the router to your computer.  
3. Connect the provided AC/AC power adaptor to the PWR jack of the router.  
Plug the adaptor into a mains power outlet. Switch on the router. The DIAG  
light will remain on for a short time indicating self-check in progress. Wait  
until the DIAG light has turned off before proceeding to the next section. In  
normal operation these three lights shall be on: PWR, LAN (or USB) and DSL.  
Section 9 of this Guide explains how these indicator lights work.

Some advanced functions of your router  
Firewall, port forwarding, DMZ & traffic restrictions  
7
By default a preset firewall is invoked to block all incoming requests including  
Ping from the Internet to your private network. In the reverse direction all requests  
sent from your network can freely pass through to the Internet.  
If you want servers on your network accessible to Internet users, set up port  
forwarding in Advanced > Virtual Servers > Port Forwarding. Refer to Chapter  
4 – NAT Virtual Servers on page 43 of the User’s Manual.  
If you run applications that require unrestricted 2-way traffic between computer  
and the Internet, set computer up as DMZ Host in Advanced > Virtual Servers  
> DMZ Host. Refer to Chapter 4 – NAT DMZ Host on page 45 of the User’s Manual.  
Caution – any DMZ host computers are no longer protected by the firewall.  
You can restrict Internet services to some computers on your network by setting  
up IP Filtering. Refer to Chapter 4 Filtering by IP address on page 47 of the  
User’s Manual.  
IP extension bridging  
In IP Extension Mode the ADSL router resembles a modem. Firewall protection  
and Internet sharing are not available. The router becomes a bridge between  
WAN & LAN. A computer or network device connected behind it receives a public  
WAN IP directly. This arrangement is suitable for certain applications that require  
a computer or network device to receive a public IP.

ADSL Router Quick Set-up Guide  
To set up IP extension, go to Advanced > Internet. Click on the "modify icon"  
under Edit:  
The next screen displays VPI and VCI as 8 and 35. Do not change these numbers.  
Go Next. Select PPPoA VC MUX or PPPoE LLC/SNAP. If your ISP did not specify  
PPPoE you can assume it is PPPoA. Go Next.  
On the next screen untick Enable NAT, and tick PPP IP extension as illustrated.  
Go Next.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Enter your Internet account user name and password. Go Next.  
The new configuration is displayed. Click Apply to confirm changes. The router  
will restart itself to activate the new setting.  
You will notice all NAT or firewall settings disappear from the Advanced menu  
hereafter. Now follow Step 2 of Section 5 – Getting On-line.  
Quality of Service (QoS)  
The router allows prioritising of upstream traffic (to the Internet) by allowing the  
user to overwrite the Type of Service (TOS) field in the IP datagram header. TOS  
parameters such as Precedence, Delay, Throughput & Reliability are described  
in the RFC791 Internet Protocol specification.  
The user specifies the traffic conditions and traffic rules. The router has three  
queues for traffic priority: high, medium and low. Low priority packets are not  
sent when there are higher priority queues. When QoS is enabled a received  
packet has the TOS field in its header overwritten by the traffic rule, subject to  
traffic conditions are met.  
The router supports both Bridge (layer 2) and IP (layer 3) QoS. The difference is  
how traffic conditions can be set. With Bridge QoS, IEEE 802.1p priorities are  
used as conditions for a traffic rule to apply. With IP QoS, it is the IP criteria  
defined by the user that determines the rule to apply.  
Please refer to the User’s Manual for other advanced functions. Always restart  
the router to activate any changes to configuration.  
Tips for security  
This Dynalink series of Broadcom chipset powered routers are highly powerful,  
secure and stable devices. To ensure that you get the maximum benefit from  
your Dynalink router Dynalink makes the following strong recommendations:  
8
Do:  
Change and keep secret your router’s admin user name and password. This  
will ensure that no unauthorised changes can be made to your settings and  
will prevent any unauthorised changes to the embedded code. A router has  
both a processor and memory and unauthorised access is highly undesirable.  
Back up your router’s configuration. This function can be found in the router’s  
Management > Backup Config menu.  
Disable UPnP if you don’t need this function. Go to Advanced > Local Network  
> UPnP to disable UPnP.  
Read about the more advanced functions of this router. They can be found  
in Chapter 4 of the User’s Manual on this CD.

ADSL Router Quick Set-up Guide  
Don’t:  
Enable any form of remote access to the router unless you are confident in  
handling the security implications. Beware that an attacker may compromise  
the router and attempt to exploit the system without your knowledge. Remote  
administration of the router opens up the opportunity to breach the security  
of your router and network. Use the built in access control list to restrict  
access to only authorised Internet hosts.  
Enable IP extension bridging without firewall protection. If the router operating  
in this mode is connected to a computer, to the minimum use a "personal  
firewall" (software) to protect the computer.  
Send your router away for repair or replacement without resetting to factory  
default, or wiping out your Internet account login details. Use the Backup  
Configuration option to store your router’s setting elsewhere. This function  
can be found in the router’s Management > Backup Config menu. When a  
replacement unit is received, restore the original setting from the backup file.  
Indicator lights  
There are 8 indicators on the front panel. Every time the router is powered on or  
reset, the DIAG light will come on indicating self-test is in progress.

Troubleshooting  
Q1. Cannot open the router control panel from my browser.  
1. Check that the router’s LAN (or USB) light is on. If not, check your Ethernet  
(or USB) cable.  
10  
2. Perform a PING test. Go to Start–Programs–MS DOS/Command Prompt (In  
Windows XP or 2000 you may click Start-Run. Enter cmd then OK). Type ping  
192.168.1.1 then press Enter. The response should be:  
Pinging 192.168.1.1 with 32 bytes of data:  
Reply from 192.168.1.1: bytes=32 time=4ms TTL=30  
….  
If you see a similar response, the router is communicating with your computer  
correctly and the problem lies elsewhere. If the result is Request timed out  
or similar failures, there may be a networking problem. Check that the LAN  
or USB cable is firmly plugged in.  
3. Disable any personal firewall or virus checker temporarily. If you are using  
Internet Explorer, go to Tools–Internet options-Security. Reset security level  
of all 4 icons to default. You can revert to your customised settings after  
configuring the router.  
4. If previously the computer had a dialup modem, check browser setting. For  
example in Internet Explorer, go to Tools–Internet options–Connections, and  
select Never dial a connection. Also check LAN Settings that the option Use  
a Proxy Server is not selected.  
5. If the router is connected to a network hub, try connecting the router directly  
to the computer in a standalone setup to eliminate any possible problem  
associated with the hub.  
6. The router’s private IP address is 192.168.1.1. To access the browser control  
panel your computer must be on the same subnet as the router. See also Q3.  
Q2. Cannot connect to Internet or cannot browse  
1. Check router’s DSL light is on. Normally it takes less than one minute to  
establish a link with the telephone exchange. The link will establish as long  
as there is signal. If the DSL light does not come on the router is not seeing  
any signal. Check that:  
ADSL service has been enabled.  
If there is a designated ADSL jackpoint for the service, make sure the router  
is connected directly into this jackpoint. Other jackpoints cannot be used.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
ADSL Router Quick Set-up Guide  
If there is no designated ADSL jackpoint, any jackpoints may be used.  
Connect the router directly into a jackpoint, or through the port marked  
MODEM on a filter.  
2. If the router’s DSL light is already on, check if router is on line. Go to the Quick  
Start menu as described in Section 5 – Getting On-line. If the router reports  
"Your DSL router is ready to connect", you are not on line. Make sure the user  
name and password have been entered in the exact format as specified by  
the ISP.  
3. Check the configuration of computer and router. If you still cannot browse,  
perform a PING test as described in Q1-2, using these addresses:  
(A) Ping www.dynalink.com.au (or any valid web address)  
(B) Ping 205.178.180.16 (or any valid public IP address)  
If both (A) & (B) reported failed response such as "request time out", and  
you assigned an IP address to your computer manually. Go to Procedure (2)  
of Section 4. Check that the router’s IP (192.168.1.1) is entered as gateway &  
DNS. If these settings are correct ping the computer’s IP (eg. Ping 192.168.1.2).  
If there is still no reply your network card may be faulty.  
If (A) fails but (B) shows a response, this is probably a DNS problem. Go to  
Procedure (2) of Section 4. Enter the router’s IP (192.168.1.1) as DNS.  
If both (A) & (B) show a response, your router is actually on line. The problem  
may be with your browser setting. Try returning any custom settings of the  
browser to default. If you have a personal firewall, disable it to see if it makes  
any difference. Also you may try shutting down the computer and restarting.  
Q3. Need to install router on a network that uses a different subnet  
If the existing network already has a DHCP server, disconnect one computer from  
the network. Connect the computer to the router. The host computer will be  
assigned 192.168.1.2. You can change the router’s IP so that it is consistent with  
the network. Disable DHCP on the router.  
Q4. Browsing is fine but I cannot run certain applications.  
You need to set up virtual servers or DMZ host. See Section 7 on Firewall & traffic  
restrictions.  
Q5. The router’s IP and/or administrative password have been modified. But  
the details have now been forgotten.  
You can restore the router to factory default by pushing a pin into the hidden  
reset button located next to the power on/off button at the back of the router.  
Push and hold for 5 seconds then release to reset router.
