Introducing DSL
Router Commander
DSL Router Commander is a user-friendly interface that allows you to initialize, view and
modify your router configurations to match the characteristics of your network environment.
1.1 Logging In
1. Place the ADSL CD-ROM into your CD-ROM Drive. You will be prompted with aMain
Menu, followed by a prompt asking you to install Acrobat Reader for viewing the
manuals. Click OK.
On the Main Menu, select RUN DSL ROUTER COMMANDER.
(If you do not see the Main Menu displayed, you may run the menu.exe file from the ADSL CD-
ROM. You may also run DSL Router Commander by running DslCom.exe file from \Tools\DSL
Router Commander folder on the CD-ROM.)
2. You will be prompted for your log in password. Enter the password as stm (factory's
default) and click OK.
(The factory default for Router IP Address and
Password is 192.168.1.1 andpassword respectively*.
Replace them with your new Router IP Address
and Password if your System Administrator has
changed them. (* "stm" for old models))

Software Manual
1. For configuration without NAT:
The range of the IP address used in this example is from 202.166.30.1 to
202.166.30.6 as restricted by subnet mask defined.
Network ID : 202.166.30.0 Broadcast ID : 202.166.30.7
The ISP will have to create a static route:
Network ID : 202.166.30.0 Subnet Mask :ff:ff:ff:f8
Next Hop Gateway : 202.166.29.154
2. For PPPoA and PPPoE:
The WAN IP and WAN Gateway will be dynamically assigned by the PPP
server. There is no need to specify the WAN IP nor to configure a default
route to the WAN Gateway.
2.1 Configuring the PCs
For PCA:
(with NAT) (without NAT)
IP = 192.168.1.11 = 202.166.30.2
Subnet mask = 255.255.255.0 = 255.255.255.248
Gateway = 192. 168.1.1 = 202.166.30.1
For PC B:
(with NAT) (without NAT)
IP = 192.168.1.12 = 202.166.30.3
Subnet mask = 255.255.255.0 = 255.255.255.248
Gateway = 192. 168.1.1 = 202.166.30.1
For PC X:
(with NAT) (without NAT)
IP = 192.168.1.23 = 202.166.30.6
Subnet mask = 255.255.255.0 = 255.255.255.248
Gateway = 192. 168.1.1 = 202.166.30.1

Software Manual
i) Select Line Configurationtab. In the Protocol section, click RFC 1483 Bridged.
ii) In the PVC section, enter the VPI and VCI values assigned by your ISP.
iii) In the IP Address section, enter all the required IP addresses assigned to you by your
ISP / SystemAdministrator.
(Depending on your ISP, you may select the option Obtain Wan SettingAutomatically.
The WAN IP Configuration, WAN Subnet Mask and Remote Gateway fields will be
grayed out. The addresses will be allocated by your ISP Server automatically.)

3.1.1 Configuring for RFC 2684 (RFC 1483) Bridged

15
Software Manual
Applicable to all protocols:
If you overwrite the default LAN IP address / Subnet Mask with new addresses
and click Apply, the following dialog box will be prompted.
Understand the instructions. Click OK to both prompts. Proceed to change your
Ethernet Card's IP / Subnet Mask by carrying out the following steps:
a) From your Windows desktop, right-click on the Network Neighborhood
icon and select Properties.
b) From the Configuration tab, select TCP/IP-> 3Com EtherLink III ISA
[3C509b-TPO] in PnP mode.
(3Com EtherLink III ISA Ethernet Card is used as an example here. Select the TCP/
IP protocol that is binded to your Network Card connecting to your router.)
Click Properties.
(If you do not see a TCP/IP
networking protocol, re-install
your Ethernet card.)
continue on next page...

Software Manual
If you have set the subnet mask of the LAN IP to 255:255:255:255, you will
not be able to run DSL Router Commander. This is because only one IP is
allowed on the LAN network and it is already allocated to the router.
c) From the IP Address tab, overwrite
the existing IP Address /Subnet
Mask to the same subnet as the
LAN IP / Subnet Mask you have
entered at the DSL Router
Commander.
Click OK and restart you system if
prompted.
You can now run the DSL Router
Commander with the new IP
address.

Software Manual
For Multiple PVCs:
vi) For multiple PVCs, click Multiple PVC.
- In theProtocol section, select RFC 1483 Bridged.
- In the IP Address section, enter the WAN IP Configuration and WAN Subnet
Mask addresses assigned to you by your ISP / System Administrator.
(The WAN IP Configuration must be a unique IP address for different set of PVC
values.)
Depending on your ISP, you may select the option Obtain Wan Setting
Automatically. The addresses will be allocated by your ISP Server automatically.
- In the PVC field, enter the new VPI and VCI values.
- Select the Framing Mode option as determined by your ISP.
- Click Add. A protocol with the new PVC values will be listed.
(To remove a PVC value, click on the respective protocol and click Remove.)
- Click Apply for changes to take effect. Upon configuration successful, you will
see a dialog box, 'Configuration Successful' prompted. ClickOK.
vii) Click Apply for changes to take effect. Upon configuration successful, you will see a
dialog box, 'Configuration Successful' prompted. Click OK.

Software Manual
3.1.1a NAT Inbound (optional)
Inbound allows you to list or set up a series of rules to determine what will happen to the
incoming traffic. By default, all incoming packets other than packets arriving in response
to outgoing traffic, will be rejected.
The Interface (e.g. wan as shown in the dialog box below) listed in the table corresponds
to your configured WAN interface.
NAT should always be enabled only on the interface connecting to the
public network or WAN, not the interface connecting to the private network.
i) To add a rule:
Enter the Port, Host IP Address and Protocol required and click Add.
•Port Refers to a 16-bit number (range from 1 to 65535) used by
transport layer protocols (UDP or TCP). Ports are used to
address application or services which run on a Server.
•Host IP Address Refers to the IP address of a local application server (e.g.
HTTP, FTP Server) that will service inbound traffic request
from Internet. The router will forward those requests
according to the list.
•Protocol Refers to the IP protocol, either TCP or UDP.
•Port/Proto Refers to thePort and Protocol used for the interface.
•New IP Addr Refers to the new IP address on the private network which
the packet’s destination IP address should be translated to.
(Illustration is based on RFC 1483 Routed)
