Preparing Your Network
In this chapter, you’ll learn what to do before configuring your router.
efore you can configure your router, you need to set up all the computers on your
network for TCP/IP networking. You also need to know certain information from your
ISP.
Configuring Windows for IP Networking
You need to configure each computer in your network for TCP/IP networking. If you plan to
use the DHCP feature (recommended), you should configure each computer to receive an IP
address automatically. See the procedure below for instructions.
If you don’t plan to use DHCP, you’ll need to manually assign an IP address to each computer.
Refer to your Windows documentation for instructions on how to do this.
TO CONFIGURE WINDOWS TO RECEIVE DYNAMIC IP ADRESSES:
1. Click Start, then choose Settings -> Network and Dial-up Connections ->
[name of your ISP connection].
A Status dialog box will appear:

Note
This procedure applies to Windows 2000 operating systems only. For Windows
95/98/ME, Windows NT, or Windows XP, consult your Windows
documentation.

Collecting ISP Information
You will need to find out some information from your ISP before you can configure your router,
such as:
 Has your ISP assigned you a static IP address, or will they assign one to you dynamically?
If they have given you a static IP, what is it?
 Does your ISP use PPPoE? If so, what is your PPPoE username and password?
Call your ISP if you’re not sure of the answers to these questions.

Basic
The Basic screen allows you to configure the basic operation of the router.
Although most users will be able to accept the default settings, every Internet Service Provider
(ISP) is different. Check with your ISP if you're not sure which settings they require.
The Basic screen is shown in the figure below.
Figure 6. Basic Screen

Note
The graphics shown in this manual may differ slightly from your router’s screens.
The images that appear here are provided as examples only.
TO CONFIGURE SETUP PARAMETERS:
1. LAN MAC Address: Shows the MAC Address ( also known as the Ethernet
address) of the LAN interface.
2. Review the LAN IP Address information and change if necessary.
These two fields show the Device IP Address and Subnet Mask as seen by others on
your Local Area Network (LAN). Most users will not need to change these values (default
IP is 192.168.1.1, subnet mask is 255.255.255.0) .
Note
If you change the LAN IP Address with the DHCP server running, you'll need
to restart your client machines. If you change the LAN IP Address without the
DHCP server running, you'll need to manually reconfigure your clients' IP
addresses.
3. LAN DHCP Server: Enable DHCP functionality on LAN.
Note
If you don’t enable DHCP on your router, you’ll need to manually configure an IP
address for each computer on your network.
4. Setup the LAN DHCP Starting IP Address and Ending IP Address.
I. Make sure there is not already a DHCP server running on your network.
II. Make sure that each computer on your network is configured to receive an IP
address automatically.
III. On the DHCP screen, click Enable.
IV. Type the
LAN DHCP Starting IP Address. The address you specify will be the
first IP address that can be assigned to a computer on the network.
V. Type the LAN DHCP Ending IP Address. The address you specify will be the last
IP address that can be assigned.

12
Example
If you choose 192.168.1.51 as the starting address and 192.168.1.100 as the
ending address, the DHCP server will assign addresses to network clients that
are between 192.168.1.51 and 192.168.1.100.
5.LAN Spanning Tree Protocol: Enables the use of the Ethernet 802.1d Spanning
Tree Protocol to eliminate bridging loops across the LAN interfacesWAN Setting:
The second part of the Basic screen is the configuration of WAN. The figure is as the
following.
1. WAN Host Name: Some ISPs require that a host name be provided when requesting an IP
address through DHCP Server.
2. WAN Domain Name: Sets the domain name to be provided to LAN clients who request an
IP address through DHCP Server.
3. WAN MAC Address: Some ISPs need that a specific MAC address be used. Also known as
MAC address cloning this feature allows you to set the MAC address of the WAN interface.
4. WAN IP Address: Sets the IP address of the WAN interface.
5. WAN Subnet Mask: Sets the IP mask of the WAN interface.
6. WAN Default Gateway: Sets the IP address of the default gateway on the WAN.
7. WAN DNS Servers: Sets the IP address of the DNS Servers to use for resolving host names.
Figure 7. Basic Screen (2)

8. WAN WINS Servers: Sets the IP address of the DNS Servers to use for resolving NetBIOS
names.
9. WAN Protocol: Sets the method to use to obtain an IP address for the WAN interface.
PPPoE and Routing Setting:
PPPoE (Point-to-Point Protocol over Ethernet) is a protocol used by many ADSL Internet
Service Providers. Roaring Penguin has a free client for Linux, NetBSD and Solaris systems to
connect to PPPoE service providers. The setting screen is shown as the figure below.
1. PPPoE Username: Sets the username to use when authenticating with a PPPoE server.
2. PPPoE Password: Sets the password to use when authenticating with a PPPoE server.
3. PPPoE Keep Alive: Sets whether the PPPoE link should be automatically restored if it
is lost. This setting has no effect if PPPoE Connect on Demand is Enable.
4. PPPoE Connect on Demand: Sets whether the PPPoE link should be automatically
disconnected if no traffic has been observed for the period specified by PPPoE Max
Idle Time.
5. PPPoE Max Idle Time: Sets the number of seconds to wait before disconnecting the
PPPoE link if PPPoE Connect on Demand is Enable.
6. PPPoE MRU: Sets the maximum number of bytes that the PPPoE interface will receive
in a single Ethernet frame.PPPoE MTU: Sets the maximum number of bytes that the
PPPoE interface will transmit in a single Ethernet frame. Make sure the value is 1400 or
smaller than 1400. Router Username: Sets the username for access to these

configuration pages. Leave this field and Router Password blank to disable access
control. Router Password: Sets the password for access to these configuration pages.
Leave this field and Router Username blank to disable access control.Router WAN
Port: Sets the WAN port to use the remote access to these configuration pages. Leave
this field blank to disable remote access.Router Mode: Router Mode is default. If you
select Access Point Mode that is disabling LAN DHCP Server, LAN Spanning Tree
Protocol, and WAN Protocol. Firewall: Sets whether the firewall should be disabled.
Connections form the WAN are allowed if the Firewall is disabled.
Note
If your ISP has provided the DHCP functionality, you should select the Router
Mode. The capability of Access Point Mode is similar to the single Hub, and
doesn’t support the DHCP function.
The other relative setting:
1. Time Zone: Sets the Time Zone of this locale.
2. NTP Server: Sets the IP address of the NTP Server to use for time synchronization.
3. Syslog IP Address: System log message will be sent to this IP address.
4. UPnP : Sets whether UniversalPlug and Play (UPnP) is enabled.

Filters
Use the Filters screen to create and apply filters that can selectively allow
traffic to pass in and out of your network. Your router comes with several
filters predefined for you.
Warning
Overwriting the factory default filters may result in your network clients not being
able to access the internet. When you define new filters, we recommend that you
choose an empty row.
The Filters screen is shown in the figure below.
Figure 11. Filter Screen (1)
1. LAN MAC Filters: Filter packets from LAN machines with the specified MAC addresses.
±
If no filters are
enabled, all traffic
will be blocked.

2. LAN IP Filters: Filter packets from LAN machines with IP addresses in the specified ranges.
3. LAN TCP Port Filters: Filter packets destined to TCP ports in the specified ranges from
LAN machines with the specified IP addresses.
4. LAN UDP Port Filters: Filter packets destined to UDP ports in the specified ranges from
LAN machines with the specified IP addresses.
Figure 12. Filter Screen (2)

Routing
Routing is the act of moving information across an internetwork from a source to a destination.
Along the way, at least one intermediate node typically is encountered. Routing is often contrasted
with bridging, which might seem to accomplish precisely the same thing to the casual observer.
The primary difference between the two is that bridging occurs at Layer 2 (the link layer) of the
OSI reference model, whereas routing occurs at Layer 3 (the network layer). This distinction
provides routing and bridging with different information to use in the process of moving
information from source to destination, so the two functions accomplish their tasks in different
ways. The Routing screen is shown in the figure below.
1. LAN TCP Port Forwards: Forward packets destined to TCP ports in the first range to the
LAN machine with the specified IP address. You may optionally specify a second range (the
ranges may not overlap and must be the same size).
¤
Figure 13. Routing Screen (1)

2. LAN UDP Forwards: Forward packets destined to UDP ports in the first range to the LAN
machine with the specified IP address. You may optionally specify a second range (the ranges
may not overlap and must be the same size).
3. DMZ IP Address: Forward all other incoming WAN packets to the LAN machine with the
specified IP address.
4. Static Routes: Set up static routes to the given networks.
