LAN (local area network) port(s): connect to Ethernet network devices, such as a PC, hub, switch,
or router. Some gateways come with a single LAN connection and some come with four LAN
connections. Depending on the connection, you may need a cross over cable or a strait through cable.
Power is where you connect the power. Make sure to observe the proper power requirements.
DSL port: This is the WAN interface which connects directly to your phone line.
1.4
LED DESCRIPTION
LAN Act/Link LED: The LAN’s LINK LED serves two purposes. If the LED is continuously lit,
the Ethernet interface is successfully connected to a device through the LAN port. If the LED is
flickering, it is an indication of any network activity.
Power LED: On indicates that the power is supplied to the gateway
DSL Sync LED: The DSL’s LINK LED serves two purposes. If the LED is continuously lit, the DSL
interface is successfully connected to a device through the WAN port. If the LED is flickering, it is an
indication that the modem is training.
PPPoE LED: The PPPoE LED is off if no PPPoE connection is established or the connection is not
used. When the PPPoE LED is green, a PPPoE connection is established.

SETTING UP YOUR GATEWAY
This section will guide you through your gateway’s configuration. The gateway is shipped with a
standard default bridge configuration; for most users, you may want to change the gateway from a
bridge to a router.
3.1
LOG INTO YOUR GATEWAY
To configure your gateway, open your web browser. You may get an error message at this point; this
is normal. Don’t panic. Continue following these directions. Type the default IP address
(192.168.1.1) Press the Enter key and the following screen, shown in Figure 1 will appear. The
default user name is Admin (case sensitive) and the password is password (case sensitive).
Note: Before setting up your gateway, make sure you have followed the quick start guide. You should
have your computers configured for DHCP mode and have proxies disabled on your browser. Also if
you access the router, and instead of getting a login screen, the browser instead displays a login
redirection screen, you should check your browser's setting, and verify that JavaScript support is
enabled. Also, if you do not get the screen shown in Figure 1, you may need to delete your temporary
Internet files (basically flush the cached web pages).

HOME SCREEN
The first screen (Figure 2) that appears (after the log in screen) is the Home screen. From this screen
the user can setup the modem (configure the LAN and WAN connection(s), configure the advanced
configuration options within the modem (security, routing, and filtering), access tools that are helpful
for debug purposes, obtain the status of the modem, and view the extensive online help.
The basic layout of the Home page consists of a page selection list across the top of the browser
window. The footer displays gateway status, connection information, and other useful information.
The center display is where most of the configuration will take place.
Figure 2 (Home page)
3.3
SETUP
To setup your gateway with a basic configuration, from the Home page, select Setup. Figure 3
illustrates the setup page. The page is broken into two subsections the WAN configuration and the
LAN configuration.
Before configuring the router, there are several concepts that you should be familiar with on how your
new router works. Please take a moment to familiarize yourself with these concepts, as it should make
the configuration much easier.

3.3.1 WIDE AREA NETWORK CONNECTION
On the other side of the router is where your Wide Area Network (WAN) connection; 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 in this area. Local Area Network Connection(s)
3.3.2 LOCAL AREA NETWORK CONNECTION
On one side of your router, you have your own Local Area network (LAN) connections. This is where
you plug in your local computers to the router. The router is normally configured to automatically
provide all the PC's on your network with Internet addresses.
3.4
CONFIGURATION THE WAN
Before the gateway will pass any data between the LAN interface(s) and the WAN interface, the
WAN side of the modem must be configured. Depending upon your DSL service provider or your
ISP, you will need some (or all) of the information outlined below before you can properly configure
the WAN:
• Your DSL line VPI and VCI
• Your DSL encapsulation type and multiplexing
• Your DSL training mode (default is MMODE)
For PPPoA or PPPoE users, you also need these values from your ISP:
• Your username and password
For RFC 1483 users, you may need these values from your ISP:
• Your DSL fixed Internet IP address
• Your Subnet Mask
• Your Default Gateway
• Your primary DNS IP address
User Manual
9
Atrie DB-120 User Manual
Since multiple users can use the gateway, the gateway can simultaneously support multiple connection
types; hence, the user must set up different profiles for each connection. The gateway supports the
following protocols:
• DHCP
• RFC 2364 PPPoA
• RFC2516 PPPoE
• Static
• Bridged
• CLIP
.
3.4.1 NEW CONNECTION
A new connection is basically a virtual connection. Your gateway can support up to 8 different
(unique) virtual connections. If you have multiple different virtual connections, you man need to
utilize the static and dynamic routing capabilities of the modem to pass data correctly.
3.4.1.1 BRIDGE GATEWAY PROFILE AND CONNECTION
A pure bridged connection does not assign and IP address to the WAN interface. NAT and firewall
rules are not enabled. This connection method makes the router act as a hub, and just passes packets
across the WAN interface to the LAN interface.
To configure the gateway as a bridge, from the Home page, click on Setup and then click on New
Connection. The default PPPoE connection setup is displayed. At the Type field select Bridge and
the Bridge connection setup page is displayed (see Figure 4). Give your Bridge connection a unique
name; the name must not have spaces and cannot begin with numbers. In this case the unique name is
called bridge1. 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 0,35. Also select the quality of service (QOS); leave the
default value if you are unsure or the ISP did not provide this information.

To complete the connection you must now click the apply button. The apply button will temporarily
save this connection. To make the change permanent you need to click on Tools (at the top of the
page) and select System Commands. At the system commands page, click on Save All.
3.4.1.2 PPPoA CONNECTION SETUP
PPPoA is also known as RFC 2364. It is a method of encapsulating PPP packets over ATM cells
which are carried over the DSL line. 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. LLC and VC are two different methods of encapsulating the PPP packet.
Contact your ISP to make sure which encapsulation is being supported.
By selecting PPPoA, you are forcing your gateway to terminate the PPPoA connection. The
advantage is that the PPPoA termination is done within the gateway and not on your PC; this frees up
your PC resources and allows multiple users to utilize the PPPoA connection.
To configure the gateway for PPPoA, click on Setup and then click on New Connection. The default
PPPoE connection setup is displayed. At the Type field select PPPoA and the PPPoA connection
setup page is displayed; figure 5 illustrates a typical PPPoA configuration. Give your PPPoA
connection a unique name; the name must not have spaces and cannot begin with numbers. In this
case the unique name is called PPPOA1. 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 0,40. Also select the quality of
service (QOS); leave the default value if you are unsure or the ISP did not provide this information.
Following is a description of the different options:
a. Username: The username for the PPPoA access; this is provided by your DSL service
provider or your ISP.
b. Password: The password for the PPPoA access; this is provided by your DSL service
provider or your ISP.
c. On-Demand: Enables on-demand mode. The connection will disconnect if no activity is
detected after the specified idle timeout value.
d. Idle Timeout: Specifies that PPPoA 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.
e. 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.
f. Maxfail: As long as a DSL connection is established, the gateway will attempt to
establish a PPPoA connection. If after n consecutive failed connection attempts the
gateway will wait for some random time before trying to establish the connection again.
A value of 0 means no limit.
g. Set Route: Specify this connection as the default-route.
h. MRU: Maximum Receive Unit the DSL connection can receive. It is a negotiated value
that asks the provider to send packets of no more than n bytes. The maximum specified
value is 1500 although some DSL/ISP providers require a larger value. The minimum
MRU value is 128.
i. Debug: Enables PPPoA connection debugging facilities. Debugging is talked about
later.

To complete the connection you must now click the apply button. The apply button will temporarily
save this connection. To make the change permanent you need to click on Tools (at the top of the
page) and select System Commands. At the system commands page, click on Save All.
3.4.1.5 STATIC CONNECTION SETUP
Static is used whenever a known static IP is assigned. The accompanying information such as the
Subnet mask and the gateway should also be specified. Up to three Domain Name Server (DNS)
addresses can also be specified. These servers would enable you to have access to other web servers.
Valid IP addresses range is from 0.0.0.0 to 255.255.255.255.
To configure the gateway for a Static connection, click on Setup and then click on New Connection.

3.5
Configuring The LAN
By default, your gateway has DHCP server (LAN side) enabled. If you already have a DHCP server
running on your network, you must disable one of the two DHCP servers; if you plug a second DHCP
server into the network, you will experience network errors and the network will not function
normally.
User Manual
16
Atrie DB-120 User Manual
3.5.1 ENABLE/DISABLE DHCP
To enable or disable DHCP go to the Home screen, Click setup. Under LAN Setup, select DHCP
Configuration. This will bring up the screen shown in Figure 10.
The Start IP Address is where the DHCP server starts issuing IP addresses. This value must be greater
than the gateways IP address value. For example if the gateways 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 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 gateway if your PC has DHCP enabled.
Figure 10 (DHCP Server configuration)
In addition to the DHCP server feature, the gateway supports the DHCP relay function. When the
gateway is configured as DHCP server, it assigns the IP addresses to the LAN clients. When the
gateway is configured as DHCP relay, it is responsible for forwarding the requests and responses
negotiating between the DHCP clients and the server. See figure 11.
User Manual
17
Atrie DB-120 User Manual
Figure 11 (Example of a DHCP Relay configuration)
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 Gateway must be on the same subnet as all the other
computers.
The apply button will temporarily save this connection. To make the change permanent you need to
click on Tools (at the top of the page) and select System Commands. At the system commands page,
click on Save All.
3.5.2 CHANGING THE GATEWAYS IP ADDRESS
You can change the gateway’s IP address by going to the Home screen, click setup and under LAN
Setup, select Management. This will bring up the screen shown in Figure 12.
3.5.2.1 STATIC IP ADDRESS ASSIGNMENT
Your gateway’s default IP address and subnet mask are 192.168.1.1/255.255.255.0; this subnet mask
will allow the gateway to support 254 users. If you want to support a larger number of users you can
change the subnet mask; but remember. 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. Figure 12
shows a default gateway address of 10.247.16.1 because this was the default gateway defined when
the CLIP connection was configured.
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 gateway’s web
pages the user can type 192.168.1.1 (the gateway’s default IP address) or type mygateway.

Advanced
The gateway supports a host of advanced features. For basic router functionality, the user does not
need to utilize these advanced features. The features help with routing, security, port configuration,
and plug and play capability.
3.6.1 UPnP
UPnP NAT and Firewall Traversal allow traffic to pass-thru the 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, from the Home screen, click Advanced and under Advanced, select UPnP. This will bring
up the screen shown in Figure 13. You must enable UPnP and then select which connection will
utilize UPnP. In this case the PPPoA connection is enabled.

3.6.2 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 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 Advanced, 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 port,
protocols and description for your application.
For example, if you want to host a Netmeeting session, from the Home screen, click Advanced and
under Advanced, 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.

Access control can also be called port blocking. Specific types of traffic that is destined to a selected
LAN IP address can be blocked. To enable any of the Access Control features, from the Home screen,
click Advanced and under Advanced, select Access Control. A page similar to the port-forwarding
page appears. Similar to the port-forwarding page, an IP address can be added to a rule. All Access
Control rules have precedence over rules that were added via the port-forwarding page.

3.6.4 LAN CLIENTS
To add a LAN client, from the Home screen, click Advanced and under Advanced, select LAN
Clients. If DHCP is used, all DHCP clients are automatically assigned. 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 to you can apply Port Forwarding and Access Control rules to this IP
address.

3.6.5 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 the defined filter rules sequentially, and
when a matched is determined, the appropriate filtering action (determined by the access type selected
User Manual
21
Atrie DB-120 User Manual
... i.e. allow or deny) is performed. The user should note that the bridge filter will only examined
frames from interfaces which are part of the bridge itself. Twenty filter rules are supported with bridge
filtering. To enable Bridge Filters, from the Home screen, click Advanced and under Advanced,
select Bridge Filters. Figure 15 illustrates a typical Bridge filter configuration.
The User Interface for Bridge Filter allows the user to add/edit/delete, as well as, enables the filter
rules. To add rules, simply define the source MAC address, destination MAC address and frame type
with desired filtering type (i.e. allow/deny), and press the “Add” button. The MAC address must be in
a xx-xx-xx-xx-xx-xx format, with 00-00-00-00-00-00 as “don’t care”. Blanks can be used in the MAC
address space, and would be considered also as “don’t care”.
To edit/modify an existing filter rule, select the desired rule created previously from “Add” in the
“Edit” select box. The selected filter rule will appear on top section, as with the “Add” filter rule.
Make the desired change to the MAC address, frame type and/or access type, and press “Apply”.
To delete filter rule(s), select the filter rule entry to delete in the “Delete” selection box. Note that
multiple deletions are possible. Once all the desired filter rule(s) is/are selected for deletion, press the
“Apply” button. The “Select All” select box can also be used to delete the entire filter rule. It provides
a quick method of selecting all filter rules for deletion.
The “Enable Bridge Filters” button allow the user to enable or disable bridge filtering. It can be
set/unset during any add/edit/delete operation. It can also be set/unset independently by just pressing
the “Apply” button.
Figure 15 (Bridge Filters)
Note: The bridge filter table contains 3 hidden rules. These rules are entered automatically by the
system to ensure the user does not "lock" them out of the system. The first rule allows any and all
ARP frames through the system. The second rule allows all IPv4 frames with the destination MAC
address of the bridge to go through. The third rule allows all IPv4 frames with the source MAC
address of the bridge to go through.
Note: On a windows based machine, to find a MAC address, ad a dos prompt type ipconfig /all.

3.6.6 MULTICAST
Multicasting is a form of limited broadcast. UDP is used to send datagrams to all hosts that belong to
what is called a "host group." A host group is a set of zero or more hosts identified by the same
destination IP address. The following statements apply to host groups.
a. Anyone can join or leave a host group at will.
b. There are no restrictions on a host's location.
c. There are no restrictions on the number of members that may belong to a host group.
d. A host may belong to multiple host groups.
e. Non-group members may send UDP datagrams to the host group.
Multicasting is useful when data needs to be sent to more than one other device. For instance, if one
device is responsible for acquiring data that many other devices need, then multicasting is a natural fit.
Note that using multicasting as opposed to sending the same data to individual devices uses less
network bandwidth.
To enable Multicasting, from the Home screen, click Advanced and under Advanced, select
Muliticast. Figure 16 illustrates a typical Multicast configuration.

3.6.7 STATIC ROUTING
If the Gateway 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 Gateway.
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
User Manual
23
Atrie DB-120 User Manual
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. The Hop Count determines the
maximum number of steps between network nodes that data packets will travel. A node is any device
on the network (such as a router or switch)
To enable Static Routing, from the Home screen, click Advanced and under Advanced, select Static
Routing. Figure 17 illustrates a typical Static Route.

click on Tools (at the top of the page) and select System Commands. At the system commands page,
click on Save All.
3.6.8 DYNAMIC ROUTING
Dynamic Routing allows the Gateway to automatically adjust to physical changes in the network. The
Gateway, 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 routers on the network.
The Direction determines the direction that RIP routes will be updated. Selecting In means that the
Gateway will only incorporate received RIP information. Selecting Out means that the Gateway will
only send out RIP information. Selecting both means that the Gateway will 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.
To enable Dynamic Routing, from the Home screen, click Advanced and under Advanced, select
Dynamic Routing. Figure 18 illustrates a typical Dynamic Route.

TOOLS
The gateway supports a host of tools which will allow you to customize and debug your gateway.
3.7.1 SYSTEM COMMANDS
To make the changes permanent you need to click on Tools (at the top of the page) and select System
Commands. The following commands are used to configure the gateway:
a.
Save all: Press this button in order to permanently save the current configuration of the
Gateway. If you do re-start the system without saving your configuration, the Gateway will
revert back to the previously saved configuration.
b.
Restart: Use this button to re-start the system. If you have not saved your configurations,
the Gateway will revert back to the previously saved configuration upon re-starting. NOTE:
Connectivity to the unit will be lost. You can reconnect after the unit reboots.
c.
Restore Defaults: Use this button to restore factory default configuration. NOTE:
Connectivity to the unit will be lost. You can reconnect after the unit reboots.
3.7.2 REMOTE LOG
The remote log feature is used in conjunction with the PC tool (software provided with your gateway).
For PPPoE and PPPoA connections, you can select debug if you want to log the connection
information. This is helpful when trying to debug connection problems.
The remote log feature will forward all logged information to the remote PC. The type of information
forwarded to the remote PC depends upon the Log level. Each log message is assigned a severity
level, which indicates how seriously the triggering event affects router functions. When you configure
User Manual
25
Atrie DB-120 User Manual
logging, you must specify a severity level for each facility; messages that belong to the facility and are
rated at that level or higher are logged to the destination
Table 1 defines the different severity levels.
To forward logging information, you need to click on Tools (at the top of the page) and select Remote
Log.
Table 1 (Severity Level)
3.7.3 USER MANAGEMENT
You can change your gateway’s username and password by going to the Home screen, under the tools
menu, click User Management. From here you can change the login name and password. You can
also change the idle timeout; you will need to log back onto the gateway once the timeout expires.
If you forget your password, you can press and hold the reset to factory defaults button for 10 seconds
(or more). The gateway will reset to its factory default configuration and all custom configurations
will be lost.
The apply button will temporarily save this connection. To make the change permanent you need to
click on Tools (at the top of the page) and select System Commands. At the system commands page,
click on Save All.
3.7.4 UPDATE GATEWAY
You can remotely upgrade the gateway’s firmware by going to the Home screen, under the tools title,
click Update Gateway. This will bring up the screen shown in Figure 19. We will provide two
different images; one image is the kernel (operating system) and the other image is the file system.
To upgrade the firmware, click browse, find the firmware file to download. Make sure this is the
correct file. Click on upgrade firmware (as shown in Figure 19). Once the upgrade is complete the
gateway will reboot. You will need to log back onto the gateway after the firmware upgrade is
complete.
The firmware upgrade should take less that 5 minutes to complete. If it takes longer than 5 minutes,
something has gone wrong.
Note: Do not remove power from the gateway during the firmware upgrade procedure.

3.7.5 PING TEST
Once you have your gateway configured, it is a good idea to make sure you can Ping the network.
You can get to the Ping web page by going to the Home screen, under the Tools title, click Ping Test.
Type the target address that you want to pin. If you have your PC connected to the gateway via the
default DHCP configuration, you should be able to Ping the network address 192.168.1.1. If your ISP
has provided their server address you can try to ping the address. If the pings for both the WAN and
the LAN side complete, and you have the proper protocols configured, you should be able to surf the
Internet.
By default when you select ping test, the gateway will ping itself 3 times. As shown in Figure 20, the
gateway passed the Ping test; this basically means that the TCP/IP protocol is up and running. If this
first Ping test does not pass, the TCP/IP protocol is not loaded for some reason; you should restart the
modem.

Check to see that the LAN and WAN LEDs are green.
Check to see that the DSL LED is green
Check the settings on your PC. Again, refer to the quick start guide for more
details
Check the gateway’s settings.
From your PC, can you PING the gateway? Assuming that the gateway has DHCP
enabled and your PC is on the same subnet as the gateway, you should be able to
PING the gateway.
Can you PING the WAN? Your ISP should have provided the IP address of their
server. If you can ping the gateway and your protocols are configured correctly,
you should be able to ping the ISPs network. If you cannot PING the ISPs
network, make sure your using the correct protocols with the correct VPI/VCI
values.
Make sure NAT is enabled for your connection. If NAT is disabled you the
gateway will not route frames correctly.
Check to see that the power LED is green and that the network cables are installed
correctly; see the quick start guide for more details.
Make sure that your PC and the gateway is on the same network segment. The
gateway’s default IP address is 192.168.1.1. If you are running a Windows based
PC, you can open a DOS window and type IPCONFIG; make sure that the network
adapter that is connected to the gateway is within the same 192.168.1.x subnet.
Also, your PC’s Subnet Mask should match the gateways subnet mask. The
gateway has a default subnet mask of 255.255.255.0.
If this still does not work, press the reset button for 10 seconds. This will place the
gateway into its factory default state. Go through the above procedures again.
Make sure NAT is enabled for your connection. If NAT is disabled you the
gateway will not route frames correctly.

ROUTER TERMS
What is a firewall?
A firewall is protection between the Internet and your local network. It acts similarly to the firewall in
your car, protecting the interior of the car from the engine. Your car's firewall has very small opening
that allow desired connections from the engine into the cabin (gas pedal connection, etc), but if
something happens to your engine, you are protected.
The firewall in the router is very similar. Only the desired connections that you allow are passed
through the firewall. These connections are normally originating from the local network; such as web
browsing, checking your email, downloading a file, and playing a game. However, in some cases, you
can allow incoming connections so that you can run programs like a web server.
What is NAT?
NAT stands for Network Address Translation. Another name for it is Connection Sharing. What does
this mean? Your ISP provides you with a single network address for you to access the Internet
through. However, you may have several machines on your local network that want to access the
Internet at the same time. The router provides NAT functionality that converts your local network
addresses to the single network address provided by your ISP. It keeps track of all these connections
and makes sure that the correct information gets to the correct local machine.
Occasionally, there are certain programs that don't work well through NAT. Some games, and some
specialty applications have a bit of trouble. The router contains special functionality to handle the vast
majority of these troublesome programs and games. NAT does cause problems when you want to run
a SERVER though. When running a server, please see the DMZ section below.
What is a DMZ?
DMZ really stands for Demilitarized Zone. It is a way of separating out part of your local network so
that is more open to the Internet. Suppose that you want to run a web-server, or a game server. Normal
servers like these are blocked from working by the NAT functionality. The solution is to "isolate" the
single local computer into a DMZ. This makes the single computer look like it is directly on the
Internet, and others can access this machine.
Your machine isn't really directly connected to the Internet, and it really has an internal local network
address. When you provide the servers network address to others, you must provide the address of the
router. The router "fakes" the connection to your machine.
You should use the DMZ when you want to run a server that others will access from the Internet.
Internal programs and servers (like print servers, etc) should NOT be connected to the DMZ
What is a Gateway?
The Internet is so large that a single network cannot handle all of the traffic and still deliver a
reasonable level of service. To overcome this limitation, the network is broken down into smaller
segments or subnets that can deliver good performance for the stations attached to that segment. This
segmentation solves the problem of supporting a large number of stations, but introduces the problem
of getting traffic from one subnet to another.
To accomplish this, devices called routers or gateways are placed between segments. If a machine
wishes to contact another device on the same segment, it transmits to that station directly using a
simple discovery technique. If the target station does not exist on the same segment as the source
station, then the source actually has no idea how to get to the target.
One of the configuration parameters transmitted to each network device is its default gateway. This
address is configured by the network administrators and it informs each personal computer or other
User Manual
32
Atrie DB-120 User Manual
network device where to send data if the target station does not reside on the same subnet as the
source. If your machine can reach all stations on the same subnet (usually a building or a sector
within a building), but cannot communicate outside of this area, it is usually because of an incorrectly
configured default gateway.
