How to Manually Configure the Primary Internet Connection

Use these steps to manually configure the primary Internet connection in the Basic Settings menu.

1.

Select your Internet connection type (broadband with or without login, or serial).

Note:

If you are a Telstra BigPond broadband customer, or if you are in an area, such as

Austria that uses broadband PPTP, login is required. If so, select BigPond or PPTP from the

Internet Service Type drop down box.

2.

Enter your Account Name (may also be called Host Name) and Domain Name. These

parameters may be necessary to access your ISP’s services, such as mail or news servers.

3.

If needed, enter the PPPoE login user name and password provided by your ISP. These fields

are case sensitive. To change the login timeout, enter a new value in minutes.

Note:

You will no longer need to run the ISP’s login program on your computer in order to

access the Internet. When you start an Internet application, your firewall automatically logs

you in.

4.

You should only disable NAT if you are sure you do not require it. NAT automatically assigns

private IP addresses (for example, 192.168.0.x) to LAN connected devices. When NAT is

disabled, only standard routing is performed by this router.

Note

: Disabling NAT will reboot the router and reset all the FWG114P v2 configuration

settings to the factory default. Disable NAT only if you plan to install the FWG114P v2 in a

setting where you will be manually administering the IP address space on the LAN side of the

router.

5.

Internet IP Address: If your ISP assigned you a permanent, fixed IP address for your computer,

select “Use Static IP Address.” Enter the IP address your ISP assigned. Also enter the IP

Subnet Mask and the Gateway IP address. The Gateway is the ISP’s router to which your

firewall will connect.

6.

Domain Name Server (DNS) Address: If your ISP does not automatically transmit DNS

addresses to the firewall during login, select “Use These DNS Servers” and enter the IP

address of your ISP’s Primary DNS Server. If a Secondary DNS Server address is available,

enter it.

Note

: A DNS server is a host on the Internet that translates Internet names (such as

www.netgear.com) to numeric IP addresses. Typically your ISP transfers the IP address of one

or two DNS servers to your firewall during login. If the ISP does not transfer an address, you

must obtain it from the ISP and enter it manually here. If you enter an address here, you should

reboot your PCs after configuring the firewall.

7.

Router’s MAC Address: This section determines the Ethernet MAC address that will be used

by the firewall on the Internet port. Some ISPs will register the Ethernet MAC address of the

network interface card in your computer when your account is first opened. They will then

only accept traffic from the MAC address of that computer. This feature allows your firewall

to masquerade as that computer by “cloning” its MAC address. To change the MAC address,

select “Use This Computer’s MAC Address.” The firewall will then capture and use the MAC

address of the computer that you are now using. You must be using the one computer that is

allowed by the ISP. Or, select “Use This MAC Address” and enter it.

Chapter 4

Wireless Configuration

This chapter describes how to configure the wireless features of your FWG114P v2 Wireless

Firewall/Print Server.

Observing 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 v2 in order to maximize the network speed.

For further information on wireless networking, refer to in

Appendix E, “Wireless Networking

Basics

.”

The operating distance or range of your wireless connection can vary significantly based on the

physical placement of the FWG114P v2 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 computer.

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

.”

Implementing Appropriate Wireless Security

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 v2 Wireless Firewall/Print Server provides highly

effective security features which are covered in detail in this chapter.

Figure 4-1:

FWG114P v2 wireless data security options

There are several ways you can enhance the security of your 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 v2. 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 wireless network

‘discovery’ feature of some products, such as Windows XP, but the data is still 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.

Note:

Indoors, computers can connect to wireless networks at ranges of 300 feet or

more. Such distances allow others outside of your area to access your network.
