Introduction
This chapter describes the features of the NETGEAR ProSafe Wireless 802.11g Firewall/Print
Server Model FWG114P.
Key Features of the FWG114P
The ProSafe Wireless 802.11g Firewall/Print Server Model FWG114P with 4-port switch
connects your LAN to the Internet through a broadband modem. With auto fail-over connectivity
through the serial port, the FWG114P provides highly reliable Internet access.
The FWG114P is a complete security solution that protects your network from attacks and
intrusions. Unlike simple Internet sharing routers that rely on Network Address Translation (NAT)
for security, the FWG114P uses Stateful Packet Inspection for Denial of Service attack (DoS)
attack protection and intrusion detection. The FWG114P allows Internet access for up to 253
users. The FWG114P Wireless Firewall/Print Server provides you with multiple Web content
filtering options, plus browsing activity reporting and instant alerts -- both via e-mail. Parents and
network administrators can establish restricted access policies based on time-of-day, Website
addresses and address keywords, and share high-speed cable/DSL Internet access for up to 253
personal computers. In addition to NAT, the built-in firewall protects you from hackers.
With minimum setup, you can install and use the router within minutes. The FWG114P Wireless
Firewall/Print Server provides the following features:
•
•
•
•
•
•
•
•
•
802.11g and 802.11b standards-based wireless networking.
Easy, web-based setup for installation and management.
Content Filtering and Site Blocking Security.
Built in 4-port 10/100 Mbps Switch.
Ethernet connection to a WAN device, such as a cable modem or DSL modem.
Extensive Protocol Support.
Login capability.
Front panel LEDs for easy monitoring of status and activity.
Flash memory for firmware upgrade.

M-10177-01
Reference Manual for the ProSafe Wireless 802.11g Firewall/Print Server Model FWG114P
802.11g and 802.11b Wireless Networking
The FWG114P Wireless Firewall/Print Server includes an 802.11b-compliant wireless access
point, providing continuous, high-speed 11 Mbps access between your wireless and Ethernet
devices. The access point provides:
•
802.11b Standards-based wireless networking at up to 11 Mbps.
•
802.11g wireless networking at up to 54 Mbps, which conform to the 802.11g standard.
•
64-bit and 128-bit WEP encryption security.
•
WEP keys can be generated manually or by passphrase.
•
Wireless access can be restricted by MAC address.
•
Wireless network name broadcast can be turned off so that only devices that have the network
name (SSID) can connect.
A Powerful, True Firewall with Content Filtering
Unlike simple Internet sharing NAT routers, the FWG114P is a true firewall, using stateful packet
inspection to defend against hacker attacks. Its firewall features include:
•
DoS protection.
Automatically detects and thwarts DoS attacks such as Ping of Death, SYN Flood, LAND
Attack, and IP Spoofing.
•
Blocks unwanted traffic from the Internet to your LAN.
•
Blocks access from your LAN to Internet locations or services that you specify as off-limits.
•
Logs security incidents.
The FWG114P will log security events such as blocked incoming traffic, port scans, attacks,
and administrator logins. You can configure the router to email the log to you at specified
intervals. You can also configure the router to send immediate alert messages to your email
address or email pager whenever a significant event occurs.
•
With its content filtering feature, the FWG114P prevents objectionable content from reaching
your PCs. The router allows you to control access to Internet content by screening for
keywords within Web addresses. You can configure the router to log and report attempts to
access objectionable Internet sites.

Introduction
M-10177-01
Reference Manual for the ProSafe Wireless 802.11g Firewall/Print Server Model FWG114P
Security
The FWG114P Wireless Firewall/Print Server is equipped with several features designed to
maintain security, as described in this section.
•
PCs Hidden by NAT: NAT opens a temporary path to the Internet for requests originating from
the local network. Requests originating from outside the LAN are discarded, preventing users
outside the LAN from finding and directly accessing the PCs on the LAN.
•
Port Forwarding with NAT: Although NAT prevents Internet locations from directly accessing
the PCs on the LAN, the router allows you to direct incoming traffic to specific PCs based on
the service port number of the incoming request, or to one designated “DNS” host computer.
You can specify forwarding of single ports or ranges of ports.
Autosensing Ethernet Connections with Auto Uplink
With its internal 8-port 10/100 switch, the FWG114P can connect to either a 10 Mbps standard
Ethernet network or a 100 Mbps Fast Ethernet network. Both the LAN and WAN interfaces are
autosensing and capable of full-duplex or half-duplex operation.
The router incorporates Auto UplinkTM technology. Each Ethernet port will automatically sense
whether the Ethernet cable plugged into the port should have a ‘normal’ connection such as to a
PC or an ‘uplink’ connection such as to a switch or hub. That port will then configure itself to the
correct configuration. This feature also eliminates the need to worry about crossover cables, as
Auto Uplink will accommodate either type of cable to make the right connection.
Extensive Protocol Support
The FWG114P Wireless Firewall/Print Server supports the Transmission Control Protocol/Internet
Protocol (TCP/IP) and Routing Information Protocol (RIP). For further information about TCP/IP,
refer to Appendix B, “Network, Routing, Firewall, and Basics.”
•
IP Address Sharing by NAT: The FWG114P Wireless Firewall/Print Server allows several
networked PCs to share an Internet account using only a single IP address, which may be
statically or dynamically assigned by your Internet service provider (ISP). This technique,
known as NAT, allows the use of an inexpensive single-user ISP account.
Introduction
2-3
M-10177-01
Reference Manual for the ProSafe Wireless 802.11g Firewall/Print Server Model FWG114P
•
Automatic Configuration of Attached PCs by DHCP: The FWG114P Wireless Firewall/Print
Server dynamically assigns network configuration information, including IP, gateway, and
domain name server (DNS) addresses, to attached PCs on the LAN using the Dynamic Host
Configuration Protocol (DHCP). This feature greatly simplifies configuration of PCs on your
local network.
•
DNS Proxy: When DHCP is enabled and no DNS addresses are specified, the router provides
its own address as a DNS server to the attached PCs. The router obtains actual DNS addresses
from the ISP during connection setup and forwards DNS requests from the LAN.
•
PPP over Ethernet (PPPoE): PPPoE is a protocol for connecting remote hosts to the Internet
over a DSL connection by simulating a dial-up connection. This feature eliminates the need to
run a login program such as Entersys or WinPOET on your PC.
•
PPTP login support for European ISPs, BigPond login for Telstra cable in Australia.
Easy Installation and Management
You can install, configure, and operate the ProSafe Wireless 802.11g Firewall/Print Server Model
FWG114P within minutes after connecting it to the network. The following features simplify
installation and management tasks:
•
Auto fail-over connectivity through an analog or ISDN modem connected to the serial port
If the broadband modem Internet connection fails, after a waiting for an amount of time you
specify, the FWG114P can automatically establish a backup ISDN or dial-up Internet
connection via the serial port on the firewall.
•
Browser-based management: Browser-based configuration allows you to easily configure your
router from almost any type of personal computer, such as Windows, Macintosh, or Linux. A
user-friendly Setup Wizard is provided and online help documentation is built into the
browser-based Web Management Interface.
•
Smart Wizard: The FWG114P Wireless Firewall/Print Server automatically senses the type of
Internet connection, asking you only for the information required for your type of ISP account.
•
Diagnostic functions: The firewall incorporates built-in diagnostic functions such as Ping,
DNS lookup, and remote reboot.
•
Remote management: The firewall allows you to login to the Web Management Interface from
a remote location on the Internet. For security, you can limit remote management access to a
specified remote IP address or range of addresses, and you can choose a nonstandard port
number.

Chapter 4
Wireless Configuration
This chapter describes how to configure the wireless features of your FWG114P Wireless
Firewall/Print Server.
Observe Performance, Placement, and Range Guidelines
In planning your wireless network, you should consider the level of security required. You should
also select the physical placement of your FWG114P in order to maximize the network speed. For
further information on wireless networking, refer to in Appendix D, “Wireless Networking
Basics.”
Note: Failure to follow these guidelines can result in significant performance
degradation or inability to wirelessly connect to the wireless firewall/print server. For
complete range and performance specifications, please see Appendix A, “Technical
Specifications.”
The operating distance or range of your wireless connection can vary significantly based on the
physical placement of the FWG114P Wireless Firewall/Print Server. The latency, data throughput
performance, and notebook power consumption also vary depending on your configuration
choices. For best results, place your wireless firewall/print server:
• Near the center of the area in which your PCs will operate.
• In an elevated location such as a high shelf where the wirelessly connected PCs have
line-of-sight access (even if through walls). The best location is elevated, such as wall
mounted or on the top of a cubicle, and at the center of your wireless coverage area for all the
mobile devices.
• Away from sources of interference, such as PCs, microwaves, and 2.4 GHz cordless phones.
Away from large metal surfaces.
Be aware that the time it takes to establish a wireless connection can vary depending on both your
security settings and placement. WEP connections can take slightly longer to establish. Also, WEP
encryption can consume more battery power on a notebook PC.

Implement Appropriate Wireless Security
Note: Indoors, computers can connect over 802.11 wireless networks at ranges of 300
feet or more. Such distances can allow for others outside of your immediate area to
access your network.
Unlike wired network data, your wireless data transmissions can extend beyond your walls and
can be received by anyone with a compatible adapter. For this reason, use the security features of
your wireless equipment. The FWG114P Wireless Firewall/Print Server provides highly effective
security features which are covered in detail in this chapter.

There are several ways you can enhance the security of you wireless network.
•
•
•
Restrict Access Based on MAC Address. You can allow only trusted PCs to connect so that
unknown PCs cannot wirelessly connect to the FWG114P. Restricting access by MAC address
adds an obstacle against unwanted access to your network, but the data broadcast over the
wireless link is fully exposed.
Turn Off the Broadcast of the Wireless Network Name SSID. If you disable broadcast of
the SSID, only devices that have the correct SSID can connect. This nullifies the wireless
network ‘discovery’ feature of some products such as Windows XP, but the data is still fully
exposed.
WEP. Wired Equivalent Privacy (WEP) data encryption provides data security. WEP Shared
Key authentication and WEP data encryption will block all but the most determined
eavesdropper.

Firewall Protection and
Content Filtering
This chapter describes how to use the content filtering features of the ProSafe Wireless 802.11g
Firewall/Print Server Model FWG114P to protect your network. These features can be found by
clicking on the Content Filtering heading in the Main Menu of the browser interface.
Firewall Protection and Content Filtering Overview
The ProSafe Wireless 802.11g Firewall/Print Server Model FWG114P provides you with Web
content filtering options, plus browsing activity reporting and instant alerts via e-mail. Parents and
network administrators can establish restricted access policies based on time-of-day, web
addresses and web address keywords. You can also block Internet access by applications and
services, such as chat or games.
A firewall is a special category of router that protects one network (the “trusted” network, such as
your LAN) from another (the “untrusted” network, such as the Internet), while allowing
communication between the two. A firewall incorporates the functions of a NAT (Network
Address Translation) router, while adding features for dealing with a hacker intrusion or attack,
and for controlling the types of traffic that can flow between the two networks. Unlike simple
Internet sharing NAT routers, a firewall uses a process called stateful packet inspection to protect
your network from attacks and intrusions. NAT performs a very limited stateful inspection in that
it considers whether the incoming packet is in response to an outgoing request, but true Stateful
Packet Inspection goes far beyond NAT.
To configure these features of your router, click on the subheadings under the Content Filtering
heading in the Main Menu of the browser interface. The subheadings are described below:

To delete a keyword or domain, select it from the list, click Delete Keyword, then click Apply.
Keyword application examples:
•
If the keyword "XXX" is specified, the URL  is blocked,
as is the newsgroup alt.pictures.XXX.
•
If the keyword “.com” is specified, only websites with other domain suffixes (such as .edu or
.gov) can be viewed.
•
If you wish to block all Internet browsing access, enter the keyword “.”.
To specify a Trusted User, enter that PC’s IP address in the Trusted User box and click Apply.
You may specify one Trusted User, which is a PC that will be exempt from blocking and
logging. Since the Trusted User will be identified by an IP address, you should configure that
PC with a fixed or reserved IP address.
Using Rules to Block or Allow Specific Kinds of Traffic
Firewall rules are used to block or allow specific traffic passing through from one side to the other.
Inbound rules (WAN to LAN) restrict access by outsiders to private resources, selectively allowing
only specific outside users to access specific resources. Outbound rules (LAN to WAN) determine
what outside resources local users can have access to.
A firewall has two default rules, one for inbound traffic and one for outbound. The default rules of
the FWG114P are:
•
Inbound: Block all access from outside except responses to requests from the LAN side.
•
Outbound: Allow all access from the LAN side to the outside.
Firewall Protection and Content Filtering
5-3
M-10177-01
Reference Manual for the ProSafe Wireless 802.11g Firewall/Print Server Model FWG114P
These default rules are shown in the Rules table of the Rules menu in Figure 5-2:
Figure 5-2: Rules menu
You may define additional rules that will specify exceptions to the default rules. By adding custom
rules, you can block or allow access based on the service or application, source or destination IP
addresses, and time of day. You can also choose to log traffic that matches or does not match the
rule you have defined.
To create a new rule, click the Add button.
To edit an existing rule, select its button on the left side of the table and click Edit.
To delete an existing rule, select its button on the left side of the table and click Delete.
To move an existing rule to a different position in the table, select its button on the left side of the
table and click Move. At the script prompt, enter the number of the desired new position and click
OK.
An example of the menu for defining or editing a rule is shown in Figure 5-3. The parameters are:

already displays many common services, but you are not limited to these choices. Use the
Services menu to add any additional services or applications that do not already appear.
•
Action. Choose how you would like this type of traffic to be handled. You can block or allow
always, or you can choose to block or allow according to the schedule you have defined in the
Schedule menu.
•
Source Address. Specify traffic originating on the LAN (outbound) or the WAN (inbound),
and choose whether you would like the traffic to be restricted by source IP address. You can
select Any, a Single address, or a Range. If you select a range of addresses, enter the range in
the start and finish boxes. If you select a single address, enter it in the start box.
•
Destination Address.The Destination Address will be assumed to be from the opposite (LAN
or WAN) of the Source Address. As with the Source Address, you can select Any, a Single
address, or a Range unless NAT is enabled and the destination is the LAN. In that case, you
must enter a Single LAN address in the start box.
•
Log. You can select whether the traffic will be logged. The choices are:
•
•
Never - no log entries will be made for this service.
Match - traffic of this type which matches the parameters and action will be logged.
Inbound Rules (Port Forwarding)
Because the FWG114P uses Network Address Translation (NAT), your network presents only one
IP address to the Internet, and outside users cannot directly address any of your local computers.
However, by defining an inbound rule you can make a local server (for example, a web server or
game server) visible and available to the Internet. The rule tells the router to direct inbound traffic
for a particular service to one local server based on the destination port number. This is also known
as port forwarding.
Note: Some residential broadband ISP accounts do not allow you to run any server
processes (such as a Web or FTP server) from your location. Your ISP may periodically
check for servers and may suspend your account if it discovers any active services at
your location. If you are unsure, refer to the Acceptable Use Policy of your ISP.
Remember that allowing inbound services opens holes in your FWG114P Wireless Firewall/Print
Server. Only enable those ports that are necessary for your network. Following are two application
examples of inbound rules:

M-10177-01
Reference Manual for the ProSafe Wireless 802.11g Firewall/Print Server Model FWG114P
Inbound Rule Example: A Local Public Web Server
If you host a public web server on your local network, you can define a rule to allow inbound web
(HTTP) requests from any outside IP address to the IP address of your web server at any time of
day. This rule is shown in Figure 5-3:
Figure 5-3: Rule example: A Local Public Web Server
Inbound Rule Example: Allowing Videoconference from Restricted Addresses
If you want to allow incoming videoconferencing to be initiated from a restricted range of outside
IP addresses, such as from a branch office, you can create an inbound rule. In the example shown
in Figure 5-4, CU-SeeMe connections are allowed only from a specified range of external IP
addresses. In this case, we have also specified logging of any incoming CU-SeeMe requests that
do not match the allowed parameters.

Considerations for Inbound Rules
•
If your external IP address is assigned dynamically by your ISP, the IP address may change
periodically as the DHCP lease expires. Consider using the Dyamic DNS feature in the
Advanced menus so that external users can always find your network.
•
If the IP address of the local server PC is assigned by DHCP, it may change when the PC is
rebooted. To avoid this, use the Reserved IP address feature in the LAN IP menu to keep the
PC’s IP address constant.
•
Local PCs must access the local server using the PCs’ local LAN address (192.168.0.99 in this
example). Attempts by local PCs to access the server using the external WAN IP address will
fail.
Outbound Rules (Service Blocking)
The FWG114P allows you to block the use of certain Internet services by PCs on your network.
This is called service blocking or port filtering. You can define an outbound rule to block Internet
access from a local PC based on:
•
•
•
•
IP address of the local PC (source address)
IP address of the Internet site being contacted (destination address)
Time of day
Type of service being requested (service port number)

Reference Manual for the ProSafe Wireless 802.11g Firewall/Print Server Model FWG114P
Outbound Rule Example: Blocking Instant Messenger
If you want to block Instant Messenger usage by employees during working hours, you can create
an outbound rule to block that application from any internal IP address to any external address
according to the schedule that you have created in the Schedule menu. You can also have the router
log any attempt to use Instant Messenger during that blocked period.
Figure 5-5: Rule example: Blocking Instant Messenger
Order of Precedence for Rules
As you define new rules, they are added to the tables in the Rules menu. For any traffic attempting
to pass through the firewall, the packet information is subjected to the rules in the order of the
entries in the Rules Table, beginning at the top and proceeding to the default rules at the bottom. In
some cases, the order of precedence of two or more rules may be important in determining the
disposition of a packet. The Move button allows you to relocate a defined rule to a new position in
the table.

Rules Menu Options
Use the Options checkboxes to enable the following:
•
Enable VPN Passthrough (IPSec, PPTP, L2TP)
If LAN users need to use VPN (Virtual Private Networking) software on their PC, and connect
to remote sites or servers, enable this checkbox. This will allow the VPN protocols (IPSec,
PPTP, L2TP) to be used. If this checkbox is not checked, these protocols are blocked.
•
Drop fragmented IP packets
If checked, all fragmented IP packets will be dropped (discarded). Normally, this should NOT
be checked.
•
Block TCP flood
If checked, when a TCP flood attack is detected, the port used will be closed, and no traffic
will be able to use that port.
•
Block UDP flood
If checked, when a UDP flood attack is detected, all traffic from that IP address will be
blocked.
•
Block non-standard packets
If checked, only known packet types will be accepted; other packets will be blocked. The
known packet types are TCP, UDP, ICMP, ESP, and GRE. Note that these are packet types, not
protocols.

Services
Services are functions performed by server computers at the request of client computers. For
example, Web servers serve web pages, time servers serve time and date information, and game
hosts serve data about other players’ moves. When a computer on the Internet sends a request for
service to a server computer, the requested service is identified by a service or port number. This
number appears as the destination port number in the transmitted IP packets. For example, a packet
that is sent with destination port number 80 is an HTTP (Web server) request.
The service numbers for many common protocols are defined by the Internet Engineering Task
Force (IETF) and published in RFC1700, “Assigned Numbers.” Service numbers for other
applications are typically chosen from the range 1024 to 65535 by the authors of the application.
Although the FWG114P already holds a list of many service port numbers, you are not limited to
these choices. Use the Services menu to add additional services and applications to the list for use
in defining firewall rules. The Services menu shows a list of services that you have defined.
To define a new service, first you must determine which port number or range of numbers is used
by the application. This information can usually be determined by contacting the publisher of the
application or from user groups of newsgroups. When you have the port number information, go
the Services menu and click on the Add Custom Service button. The Add Services menu will
appear.
To add a service,
1.
Enter a descriptive name for the service so that you will remember what it is.
2.
Select whether the service uses TCP or UDP as its transport protocol.
If you can’t determine which is used, select both.
3.
Enter the lowest port number used by the service.
4.
Enter the highest port number used by the service.
If the service only uses a single port number, enter the same number in both fields.
5.
Click Apply.
The new service will now appear in the Services menu, and in the Service name selection box in
the Rules menu.

Using a Schedule to Block or Allow Specific Traffic
If you enabled content filtering in the Block Sites menu, or if you defined an outbound rule to use
a schedule, you can set up a schedule for when blocking occurs or when access is restricted. The
router allows you to specify when blocking will be enforced by configuring the Schedule tab
shown below:
Figure 5-6: Schedule menu
To block keywords or Internet domains based on a schedule, select Every Day or select one or
more days. If you want to limit access completely for the selected days, select All Day. Otherwise,
If you want to limit access during certain times for the selected days, type a Start Blocking time
and an End Blocking time.

Print Server
This chapter describes how to install and configure the print server in your ProSafe Wireless
802.11g Firewall/Print Server Model FWG114P.
Network Printing from Windows
The FWG114P Wireless Firewall/Print Server supports two methods for printing from Windows:
•
Print Port Driver
After installing the Print Port Driver, Windows users can print directly to the firewall. Print
jobs are spooled (queued) on each PC. The supplied Print Port Driver supports Windows 95/
98/ME, NT4.0, Windows 2000 and Windows XP.
•
LPD/LPR Printing
If using Windows NT 4.0 Server or Windows 2000 Server, LPD/LPR printing can be used. No
software needs to be installed on either the Windows Server or each client PC. Print jobs will
be spooled (queued) on the Windows Server, and can be managed using the standard Windows
Server tools.
Installing the PTP Driver
The following procedure is for all versions of Windows (95/98/ME, NT4.0, 2000, XP). The
Windows "Add Printer" screens will vary depending on your version or Windows, but the
procedure is the same:
1.
Make sure that the printer is ON and connected to the firewall’s printer port.
2.
Insert the supplied CD-ROM into your drive. If the setup program does not start automatically,
run SETUP.EXE in the root folder.
3.

Normally, this option should be Enabled, so that an Internet connection will be made
automatically, whenever Internet-bound traffic is detected. In locations where Internet access
is billed by the minute, if this causes high connection costs, you can disable this setting.

Setting Up a Default DMZ Server
Note: DMZ servers pose a security risk. A computer designated as the default DMZ
server loses much of the protection of the firewall, and is exposed to exploits from the
Internet. If compromised, the DMZ server can be used to attack your network.
The use of the term ‘DMZ’ has become common, although it is a misnomer. In traditional
firewalls, a DMZ is actually a separate physical network port. A true DMZ port is for
connecting servers that require greater access from the outside, and will therefore be provided
with a different level of security by the firewall. A better term for our application is Exposed
Host.
The default DMZ server feature is helpful when using some online games and
videoconferencing applications that are incompatible with NAT. The router is programmed to
recognize some of these applications and to work properly with them, but there are other
applications that may not function well. In some cases, one local PC can run the application
properly if that PC’s IP address is entered as the default DMZ server.
Incoming traffic from the Internet is normally discarded by the router unless the traffic is a
response to one of your local computers or a service that you have configured in the Ports
menu. Instead of discarding this traffic, you can have it forwarded to one computer on your
network. This computer is called the Default DMZ Server.
The WAN Setup menu, shown below lets you configure a Default DMZ Server.
To assign a computer or server to be a Default DMZ server, follow these steps:
Click WAN Setup link on the Advanced section of the main menu.
Type the IP address for that server. To remove the default DMZ server, replace the IP
address numbers with all zeros.
3. Click Apply.

Respond to Ping on Internet WAN Port
If you want the router to respond to a 'ping' from the Internet, click the ‘Respond to Ping on
Internet WAN Port’ check box. This should only be used as a diagnostic tool, since it allows
your router to be discovered. Don't check this box unless you have a specific reason to do so.

Setting the MTU Size
The default MTU size is usually fine. The normal MTU (Maximum Transmit Unit) value for
most Ethernet networks is 1500 Bytes. For some ISPs, particularly some using PPPoE, you
may need to reduce the MTU. This should not be done unless you are sure it is necessary for
your ISP.
Any packets sent through the router that are larger than the configured MTU size will be
repackaged into smaller packets to meet the MTU requirement. To change the MTU size,
under MTU Size, enter a new size between 64 and 1500. Then, click Apply to save the new
configuration.
•
Setting the WAN Port Speed
In most cases, your router can automatically determine the connection speed of the Internet
(WAN) port. If you cannot establish an Internet connection and the Internet LED blinks
continuously, you may need to manually select the port speed.
If you know that the Ethernet port on your broadband modem supports 100BaseT, select
100M; otherwise, select 10M.
How to Configure Dynamic DNS
If your network has a permanently assigned IP address, you can register a domain name and have
that name linked with your IP address by public Domain Name Servers (DNS). However, if your
Internet account uses a dynamically assigned IP address, you will not know in advance what your
IP address will be, and the address can change frequently. In this case, you can use a commercial
dynamic DNS service, which will allow you to register your domain to their IP address, and will
forward traffic directed to your domain to your frequently-changing IP address.
The router contains a client that can connect to a dynamic DNS service provider. To use this
feature, you must select a service provider and obtain an account with them. After you have
configured your account information in the router, whenever your ISP-assigned IP address
changes, your router will automatically contact your dynamic DNS service provider, log in to your
account, and register your new IP address.
1.
Log in to the router at its default LAN address of http://192.168.0.1 with its default user name
of admin, default password of password, or using whatever password and LAN address you
have chosen for the router.
2.
From the Main Menu of the browser interface, under Advanced, click on Dynamic DNS.
Advanced Configuration
8-3
M-10177-01
Reference Manual for the ProSafe Wireless 802.11g Firewall/Print Server Model FWG114P
3.
Access the website of one of the dynamic DNS service providers whose names appear in the
‘Select Service Provider’ box, and register for an account.
For example, for dyndns.org, go to www.dyndns.org.
4.
Select the “Use a dynamic DNS service” check box.
5.
Select the name of your dynamic DNS Service Provider.
6.
Type the host name that your dynamic DNS service provider gave you.
The dynamic DNS service provider may call this the domain name. If your URL is
myName.dyndns.org, then your host name is “myName.”
7.
Type the user name for your dynamic DNS account.
8.
Type the password (or key) for your dynamic DNS account.
9.
If your dynamic DNS provider allows the use of wildcards in resolving your URL, you may
select the Use wildcards check box to activate this feature.
For example, the wildcard feature will cause *.yourhost.dyndns.org to be aliased to the same
IP address as yourhost.dyndns.org
10. Click Apply to save your configuration.
Note: If your ISP assigns a private WAN IP address such as 192.168.x.x or 10.x.x.x, the
dynamic DNS service will not work because private addresses will not be routed on the
Internet.

Using the LAN IP Setup Options
The second feature category under the Advanced heading is LAN IP Setup. This menu allows
configuration of LAN IP services such as DHCP and RIP. From the Main Menu of the browser
interface, under Advanced, click on LAN IP Setup to view the LAN IP Setup menu, shown below.
Figure 8-2: LAN IP Setup Menu
Configuring LAN TCP/IP Setup Parameters
The router is shipped preconfigured to use private IP addresses on the LAN side, and to act.as a
DHCP server. The router’s default LAN IP configuration is:
•
•
LAN IP addresses—192.168.0.1
Subnet mask—255.255.255.0
These addresses are part of the IETF-designated private address range for use in private networks,
and should be suitable in most applications. If your network has a requirement to use a different IP
addressing scheme, you can make those changes in this menu.
Advanced Configuration
8-5
M-10177-01
Reference Manual for the ProSafe Wireless 802.11g Firewall/Print Server Model FWG114P
The LAN IP parameters are:
•
IP Address
This is the LAN IP address of the router.
•
IP Subnet Mask
This is the LAN Subnet Mask of the router. Combined with the IP address, the IP Subnet Mask
allows a device to know which other addresses are local to it, and which must be reached
through a gateway or router.
•
RIP Direction
RIP (Router Information Protocol) allows a router to exchange routing information with other
routers. The RIP Direction selection controls how the router sends and receives RIP packets.
Both is the default.
— When set to Both or Out Only, the router will broadcast its routing table periodically.
— When set to Both or In Only, it will incorporate the RIP information that it receives.
— When set to None, it will not send any RIP packets and will ignore any RIP packets
received.
•
RIP Version
This controls the format and the broadcasting method of the RIP packets that the router sends.
(It recognizes both formats when receiving.) By default, this is set for RIP-1.
— RIP-1 is universally supported. RIP-1 is probably adequate for most networks, unless you
have an unusual network setup.
— RIP-2 carries more information. RIP-2B uses subnet broadcasting.
Note: If you change the LAN IP address of the router while connected through the
browser, you will be disconnected. You must then open a new connection to the new IP
address and log in again.
Using the Router as a DHCP server
By default, the router will function as a DHCP (Dynamic Host Configuration Protocol) server,
allowing it to assign IP, DNS server, and default gateway addresses to all computers connected to
the router's LAN. The assigned default gateway address is the LAN address of the router. IP
addresses will be assigned to the attached PCs from a pool of addresses specified in this menu.
Each pool address is tested before it is assigned to avoid duplicate addresses on the LAN.
8-6
Advanced Configuration
M-10177-01
Reference Manual for the ProSafe Wireless 802.11g Firewall/Print Server Model FWG114P
For most applications, the default DHCP and TCP/IP settings of the router are satisfactory. See “IP
Configuration by DHCP” on page B-10 for an explanation of DHCP and information about how to
assign IP addresses for your network.
If another device on your network will be the DHCP server, or if you will manually configure the
network settings of all of your computers, clear the ‘Use router as DHCP server’ check box.
Otherwise, leave it checked.
Specify the pool of IP addresses to be assigned by setting the Starting IP Address and Ending IP
Address. These addresses should be part of the same IP address subnet as the router’s LAN IP
address. Using the default addressing scheme, you should define a range between 192.168.0.2 and
192.168.0.253, although you may wish to save part of the range for devices with fixed addresses.
The router will deliver the following parameters to any LAN device that requests DHCP:
•
An IP Address from the range you have defined
•
Subnet Mask
•
Gateway IP Address (the router’s LAN IP address)
•
Primary DNS Server (if you entered a Primary DNS address in the Basic Settings menu;
otherwise, the router’s LAN IP address)
•
Secondary DNS Server (if you entered a Secondary DNS address in the Basic Settings menu
Using Address Reservation
When you specify a reserved IP address for a PC on the LAN, that PC will always receive the
same IP address each time it access the router’s DHCP server. Reserved IP addresses should be
assigned to servers that require permanent IP settings.
To reserve an IP address:
1.
Click the Add button.
2.
In the IP Address box, type the IP address to assign to the PC or server.
(choose an IP address from the router’s LAN subnet, such as 192.168.0.X)
3.
Type the MAC Address of the PC or server.
(Tip: If the PC is already present on your network, you can copy its MAC address from the
Attached Devices menu and paste it here.)
4.
Click Apply to enter the reserved address into the table.
Advanced Configuration
8-7
M-10177-01
Reference Manual for the ProSafe Wireless 802.11g Firewall/Print Server Model FWG114P
Note: The reserved address will not be assigned until the next time the PC contacts the router's
DHCP server. Reboot the PC or access its IP configuration and force a DHCP release and renew.
To edit or delete a reserved address entry:
1.
Click the button next to the reserved address you want to edit or delete.
2.
Click Edit or Delete.
Configuring Static Routes
Static Routes provide additional routing information to your router. Under normal circumstances,
the router has adequate routing information after it has been configured for Internet access, and
you do not need to configure additional static routes. You must configure static routes only for
unusual cases such as multiple routers or multiple IP subnets located on your network.
From the Main Menu of the browser interface, under Advanced, click on Static Routes to view the
Static Route menu.
To add or edit a Static Route:
1.
Click the Add button to open the Static Routes menu.

2.
Type a route name for this static route in the Route Name box under the table.
(This is for identification purpose only.)
3.
Select Private if you want to limit access to the LAN only. The static route will not be reported
in RIP.
4.
Select Active to make this route effective.
5.
Type the Destination IP Address of the final destination.
6.
Type the IP Subnet Mask for this destination.
If the destination is a single host, type 255.255.255.255.
7.
Type the Gateway IP Address, which must be a router on the same LAN segment as the router.
8.
Type a number between 1 and 15 as the Metric value.
This represents the number of routers between your network and the destination. Usually, a
setting of 2 or 3 works, but if this is a direct connection, set it to 1.
9.
Click Apply to have the static route entered into the table.
As an example of when a static route is needed, consider the following case:
•
Your primary Internet access is through a cable modem to an ISP.
•
You have an ISDN router on your home network for connecting to the company where
you are employed. This router’s address on your LAN is 192.168.0.100.
•
Your company’s network is 134.177.0.0.
When you first configured your router, two implicit static routes were created. A default route was
created with your ISP as the gateway, and a second static route was created to your local network
for all 192.168.0.x addresses. With this configuration, if you attempt to access a device on the
134.177.0.0 network, your router will forward your request to the ISP. The ISP forwards your
request to the company where you are employed, and the request will likely be denied by the
company’s firewall.
In this case you must define a static route, telling your router that 134.177.0.0 should be accessed
through the ISDN router at 192.168.0.100. The static route would look like Figure 8-3.
In this example:
•
The Destination IP Address and IP Subnet Mask fields specify that this static route applies to
all 134.177.x.x addresses.
•
The Gateway IP Address fields specifies that all traffic for these addresses should be
forwarded to the ISDN router at 192.168.0.100.
Advanced Configuration
8-9
M-10177-01
Reference Manual for the ProSafe Wireless 802.11g Firewall/Print Server Model FWG114P
•
A Metric value of 1 will work since the ISDN router is on the LAN.
•
Private is selected only as a precautionary security measure in case RIP is activated.
Enabling Remote Management Access
Using the Remote Management page, you can allow a user or users on the Internet to configure,
upgrade and check the status of your FWG114P Wireless Firewall/Print Server.
Note: Be sure to change the router's default configuration password to a very secure
password. The ideal password should contain no dictionary words from any language,
and should be a mixture of letters (both upper and lower case), numbers, and symbols.
Your password can be up to 30 characters.
To configure your router for Remote Management:
1.
Select the Turn Remote Management On check box.
2.
Specify what external addresses will be allowed to access the router’s remote management.
Note: For enhanced security, restrict access to as few external IP addresses as practical.
3.
a.
To allow access from any IP address on the Internet, select Everyone.
b.
To allow access from a range of IP addresses on the Internet, select IP address range.
Enter a beginning and ending IP address to define the allowed range.
c.
To allow access from a single IP address on the Internet, select Only this PC.
Enter the IP address that will be allowed access.
Specify the Port Number that will be used for accessing the management interface.
Web browser access normally uses the standard HTTP service port 80. For greater security,
you can change the remote management web interface to a custom port by entering that
number in the box provided. Choose a number between 1024 and 65535, but do not use the
number of any common service port. The default is 8080, which is a common alternate for
HTTP.
4.
Click Apply to have your changes take effect.
Note: When accessing your router from the Internet, you will type your router's WAN IP address
into your browser's Address (in IE) or Location (in Netscape) box, followed by a colon (:) and the
custom port number. For example, if your external address is 134.177.0.123 and you use port
number 8080, you must enter in your browser: http://134.177.0.123:8080

Using Universal Plug and Play (UPnP)
Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers,
access the network and connect to other devices as needed. UPnP devices can
automatically discover the services from other registered UPnP devices on the network.
Figure 8-4.
UPnP Menu
Turn UPnP On: UPnP can be enabled or disabled for automatic device configuration. The default
setting for UPnP is enabled. If disabled, the router will not allow any device to automatically
control the resources, such as port forwarding (mapping), of the router.
Advertisement Period: The Advertisement Period is how often the router will broadcast its UPnP
information. This value can range from 1 to 1440 minutes. The default period is 30 minutes.
Shorter durations will ensure that control points have current device status at the expense of
additional network traffic. Longer durations may compromise the freshness of the device status
but can significantly reduce network traffic.
Advertisement Time To Live: The time to live for the advertisement is measured in hops (steps)
for each UPnP packet sent. The time to live hop count is the number of steps a broadcast packet is
allowed to propagate for each UPnP advertisement before it disappears. The number of hops can
range from 1 to 255. The default value for the advertisement time to live is 4 hops, which should
be fine for most home networks. If you notice that some devices are not being updated or reached
correctly, then it may be necessary to increase this value a little.
UPnP Portmap Table: The UPnP Portmap Table displays the IP address of each UPnP device
that is currently accessing the router and which ports (Internal and External) that device has
opened. The UPnP Portmap Table also displays what type of port is opened and if that port is still
active for each IP address.

Troubleshooting
This chapter gives information about troubleshooting your ProSafe Wireless 802.11g Firewall/
Print Server Model FWG114P. After each problem description, instructions are provided to help
you diagnose and solve the problem.
Basic Functioning
After you turn on power to the router, the following sequence of events should occur:
1.
When power is first applied, verify that the PWR LED is on.
2.
After approximately 10 seconds, verify that:
a.
The TEST LED is not lit.
b.
The LAN port LEDs are lit for any local ports that are connected.
c.
The Internet port LED is lit.
d.
The Wireless 802.11a is off and the LED is not lit until the country selection has been set.
If a port’s LED is lit, a link has been established to the connected device. If a LAN port is
connected to a 100 Mbps device, verify that the port’s LED is green. If the port is 10 Mbps, the
LED will be amber.
If any of these conditions does not occur, refer to the appropriate following section.
Power LED Not On
If the Power and other LEDs are off when your router is turned on:
•
Make sure that the power cord is properly connected to your router and that the power supply
adapter is properly connected to a functioning power outlet.
•
Check that you are using the 12 V DC power adapter supplied by NETGEAR for this product.
If the error persists, you have a hardware problem and should contact technical support.
Troubleshooting
9-1
M-10177-01
Reference Manual for the ProSafe Wireless 802.11g Firewall/Print Server Model FWG114P
LEDs Never Turn Off
When the router is turned on, the LEDs turns on for about 10 seconds and then turn off. If all the
LEDs stay on, there is a fault within the router.
If all LEDs are still on one minute after power up:
•
Cycle the power to see if the router recovers.
•
Clear the router’s configuration to factory defaults. This will set the router’s IP address to
192.168.0.1. This procedure is explained in “Restoring the Default Configuration and
Password” on page 7-7.
If the error persists, you might have a hardware problem and should contact technical support.
LAN or Internet Port LEDs Not On
If either the LAN LEDs or Internet LED do not light when the Ethernet connection is made, check
the following:
•
Make sure that the Ethernet cable connections are secure at the router and at the hub or
workstation.
•
Make sure that power is turned on to the connected hub or workstation.
•
Be sure you are using the correct cable:
When connecting the router’s Internet port to a broadband modem, use the cable that was
supplied with the broadband modem. This cable could be a standard straight-through Ethernet
cable or an Ethernet crossover cable.
