Most operating systems include the software components you need for networking with TCP/IP:
Windows
®
95 or later includes the software components for establishing a TCP/IP network.
Windows 3.1 does not include a TCP/IP component. You need to purchase a third-party TCP/
IP application package such as NetManage Chameleon.
Macintosh Operating System 7 or later includes the software components for establishing a
TCP/IP network.
All versions of UNIX or Linux include TCP/IP components. Follow the instructions provided
with your operating system or networking software to install TCP/IP on your computer.
In your IP network, each PC and the firewall must be assigned a unique IP addresses. Each PC
must also have certain other IP configuration information such as a subnet mask (netmask), a
domain name server (DNS) address, and a default gateway address. In most cases, you should
install TCP/IP so that the PC obtains its specific network configuration information automatically
from a DHCP server during bootup. For a detailed explanation of the meaning and purpose of
these configuration items, refer to “
Appendix B, “Network, Routing, Firewall, and Basics
.”
The MR814 v3 router is shipped preconfigured as a DHCP server. The firewall assigns the
following TCP/IP configuration information automatically when the PCs are rebooted:
PC or workstation IP addresses—192.168.0.2 through 192.168.0.254
Subnet mask—255.255.255.0
Gateway address (the firewall)—192.168.0.1
These addresses are part of the IETF-designated private address range for use in private networks.
Configuring Windows 95, 98, and Me for TCP/IP Networking
As part of the PC preparation process, you need to manually install and configure TCP/IP on each
networked PC. Before starting, locate your Windows CD; you may need to insert it during the
TCP/IP installation process.
Install or Verify Windows Networking Components
To install or verify the necessary components for IP networking:
1.
On the Windows taskbar, click the Start button, point to Settings, and then click Control Panel.
2.
Double-click the Network icon.

The Network window opens, which displays a list of installed components:
You must have an Ethernet adapter, the TCP/IP protocol, and Client for Microsoft Networks.
If you need to install a new adapter, follow these steps:
a.
Click the Add button.
b.
Select Adapter, and then click Add.
c.
Select the manufacturer and model of your Ethernet adapter, and then click OK.
If you need TCP/IP:

Click the Add button.
b.
Select Protocol, and then click Add.
c.
Select Microsoft.
Note:
It is not necessary to remove any other network components shown in the
Network window in order to install the adapter, TCP/IP, or Client for Microsoft
Networks.

Restart your PC for the changes to take effect.
Enabling DHCP to Automatically Configure TCP/IP Settings in
Windows 95B, 98, and Me
After the TCP/IP protocol components are installed, each PC must be assigned specific
information about itself and resources that are available on its network. The simplest way to
configure this information is to allow the PC to obtain the information from a DHCP server in the
network.
You will find there are many similarities in the procedures for different Windows systems
when using DHCP to configure TCP/IP.
The following steps will walk you through the configuration process for each of these
versions of Windows.
