How to configure the Home Network for NIS, NIS Pro, or NPF 2002 4.x
Situation:
You have an internal network and want to configure Norton Internet Security (NIS), Norton Internet Security Professional Edition (NIS Pro), or Norton Personal Firewall (NPF) 2002 4.x to work on your home network.
Solution:
NIS, NIS Pro, and NPF 2002 provides a Home Network Wizard that can be used to configure and recognize all computers on your internal network. If the Home Network Wizard does not work on your internal network, or you want to manually setup NIS or NPF for a Home Network, see the section To manually configure the Home Network.
NOTES:
You must be logged on with Administrator rights under Windows NT, 2000, and XP to perform these steps. Also, you must be logged on with Supervisor rights under NIS or NPF. To log on with Supervisor rights under NIS or NPF 2003, open NIS or NPF and look at the entry "Settings for". If the value in that box does not say Supervisor, then click the down arrow an choose Supervisor.
NOTE: The sections below are collapsed. Click the triangle to the left of the section title to expand a section and see its contents, .
To automatically configure the Home Network Wizard (Click the triangle):
1. Open the NIS main program window.
2. Click Personal Firewall.
3. Click the Internet Zone Control subcategory.
4. Click the Trusted tab.
5. Click the Wizard button.
6. The Home Network Wizard screen appears. Click Next.
NIS/NPF will automatically scan your internal network for adapters.
NOTE: During the scan, the wizard attempts to detect IP addresses beginning with 10, 172.16-31, or 192.168. If any of these IP addresses are not detected, then NIS/NPF determines that a home network does not exist and displays the following screen:
NIS/NPF will then display information about each network adapter. The Subnet Address, Subnet Mask, and Hardware Address are automatically assigned. If there are multiple network cards on the network, then each Adapter card will be listed with a different Subnet Address and Subnet Mask for each one.
7. Click Next.
The final screen of the Home Network Wizard appears.
8. Click Finish.
9. The Internet Zone Control screen will show the Type and Address information for your network.
To manually configure the Home Network (Click the triangle):
Manually configuring a home network with Norton Internet Security (NIS) or Norton Personal Firewall (NPF) is easy.
The new NIS/NPF feature "Internet Zones" was created primarily for home networks. Internet Zones consists of two lists of computers (listed by IP address or computer name). One list, "Trusted", is for computers that are permitted full access to your computer. The second list, "Restricted", is for computers that have no access to your computer. Trusted computers effectively bypass the personal firewall and have full access to your computer, while Restricted computers are always blocked.
By adding the other computers on your home network to the "Trusted" list, you effectively disable NIS/NPF for all communications between your computer and theirs. There are no rules to create or modify.
To manually set up a Home Network with NIS/NPF:
1. Write down the IP address for each computer on your home network.
NOTE: If you do not know how to determine the IP address for a computer, see the document How to determine your computer's IP address.
2. Start NIS/NPF.
3. Click Personal Firewall.
4. Click Internet Zone Control.

2. Start NIS/NPF.
3. Click Personal Firewall.
4. Click Internet Zone Control.
7. Type the computer name or IP address of each computer on your network (excluding your own). How you do this depends on the addresses themselves. See the section, Entering the computer name or Entering IP Addresses if you have questions.
8. Click OK. The addresses you entered appear on the Trusted tab.
Entering the computer name
NIS or NPF 2002 performs a DNS lookup of the name you enter to find the true, current IP address of the allowed (Trusted) computer. A workgroup or NetBios name will fail when looked up on a DNS server. To enter the computer name desired, you will need to enter the fully qualified computer.domain name.
In this example, the computer name being used is SymTest1 and the domain name is Symantec.com. To properly use the computer.domain name in this case, you would need to enter SymTest1.Symantec.com.
How to find the computer name
Determine which version of Windows you are running, and see the appropriate instructions to find the computer name you want to add to the Trusted zone.
Windows 98/Me:
1. Click Start.
2. Click Run.
3. Type winipcfg into the box and click OK or press the Enter key.
4. Click More Info>> to obtain details.
5. The computer.domain name can be found in the Host Name field.
Windows NT/2000/XP:
1. Click Start.
2. Click Run.
3. Type cmd and click OK or press the Enter key.
4. Type ipconfig/all following the DOS prompt in the command line window that appears and press Enter on your keyboard.
5. In the fields labeled Host Name and Primary Dns Suffix you will see the computer and the domain name. You may need to scroll up to see these entries.
6. Combine the computer.domain name to receive the full name of the computer you want to Trust or Restrict. For example, if Host Name is SymTest1 and the Primary Dns Suffix is Symantec.com, the name you need is SymTest1.Symantec.com.
NOTE:
These names do not have an entry on your DNS servers. You will not be able to enter these names into Norton Internet Security. You may need to contact your Internet Service Provider (ISP) for assistance in discovering the fully qualified name(s) of your computer(s) as they appear on your ISP's DNS server.
You will need to know the DNS name of each computer, even if they are not running the Windows operating system or an unsupported operating system.
If you are using an internal network that is not connected to the Internet and want to use names instead of private IP addresses, you will need to add the computer name to the Windows Host file on all the computers on the private network along with their private IP address. This procedure will allow you to add a simple name like Bob and assign it the IP address 10.0.0.5 within the hosts file. When NIS/NPF performs a DNS lookup of Bob, it will find the Host file and accept it as a valid IP address. This will only work if a domain is not assigned to the computer on which NIS/NPF is installed. If a domain has been entered, all names on the private network will need to have a dot (.) in the name. For example, Bobs.Computer. If this is done, the domain will not be inherently attached to the name Bob and NIS/NPF will be able to find it in the local Hosts file.
Entering IP addresses
When you are adding IP addresses to the Trusted list, the Specify Computers window presents you with three choices:
Individually
Using a range
Using a network address
In most home network situations, you will enter addresses individually or in a range. If you enter addresses individually, you can type them one at a time with a space between each address. If your addresses are in numerical sequence, you can still add them individually or add them by "Using a range."
Example
You have the following five computers on your home network:
192.168.1.1
192.168.1.2
192.168.1.3
192.168.1.4
192.168.1.5
You can enter them individually in the Specify Computers window:
Click OK. The computers now appear on the Trusted list.
However, because the addresses are sequential, you can also add them as a range:
Click OK. The computers now appear on the Trusted list.
Considerations
If each computer on your home network has its own connection to the Internet through a common hub, their addresses may be dynamically assigned by the Internet Service Provider. This can be problematic in situations where losing and re-establishing a connection (and thereby gaining a new IP address) is a relatively common occurrence.
If your home network uses Internet Connection Sharing software (such as Microsoft ICS or Winproxy), the only computer you have to trust is the computer connected with the physical connection to the Internet. That computer must trust everyone on the home network.
Remember: Any computer you trust has full access to your computer.

How to configure the Home Network for NIS or NPF 2003 and the Workgroup Network for NIS Pro 2003
Situation:
You have a home network and want to configure Norton Internet Security (NIS), Norton Internet Security Professional Edition (NIS Pro), or Norton Personal Firewall (NPF) 2003 to work with it.
Solution:
NIS and NPF 2003 provide a Home Networking Wizard to configure and recognize all computers on your home network. For NIS Pro 2003, this is called the Workgroup Networking Wizard. If the Home/Workgroup Networking Wizard does not work on your home network, or you want to manually set up NIS or NPF on a Home or Workgroup Network, see the section To manually configure the Home or Workgroup Network.
NOTE: You must be logged on with Administrator rights under Windows NT, 2000, and XP to perform these steps. You must be logged on with Supervisor rights under NIS or NPF.
The Home Networking Wizard and the Workgroup Networking Wizard are the fastest ways to organize computers into zones. If you have more than one computer on your network, you will want to add all of these computers to the Trusted Zone.
NOTE: Only add external computers to your Trusted Zone if you know that their users can be trusted and they have firewall software installed.
To automatically configure the Home or Workgroup Networking Wizard
1. Open the NIS, NPF, or NIS Pro main program window.
2. Double-click Personal Firewall.
3. Click the Home or Workgroup Networking tab.
4. Click the Wizard button. The Home or Workgroup Network Wizard screen appears.
5. Click Next. NIS, NPF, or NIS Pro will scan your internal network for adapters. NIS, NPF, and NIS Pro will display information about each network adapter. The Subnet Address, Subnet Mask, and Hardware Address are automatically assigned. If there are multiple network cards on the network, then each Adapter card will be listed with a different Subnet Address and Subnet Mask for each one.
6. Click Next.
7. Click Finish.
To manually configure the Home orWorkgroup Network
1. Write down the IP address for each computer on your home network.
NOTE: If you do not know how to determine the IP address for a computer, see the document How to determine your computer's IP address.
