Ethernet Cabling
Although Ethernet networks originally used thick or thin coaxial cable, most installations currently
use unshielded twisted pair
(UTP) cabling. The UTP cable contains eight conductors, arranged in
four twisted pairs, and terminated with an RJ45 type connector. A normal straight-through UTP
Ethernet cable follows the EIA568B standard wiring as described in
Table 6-1
.
Uplink Switches, Crossover Cables, and MDI/MDIX Switching
In the wiring table above, the concept of transmit and receive are from the perspective of the PC,
which is wired as Media Dependant Interface
(MDI). In this wiring, the PC transmits on pins 1 and
2. At the hub, the perspective is reversed, and the hub receives on pins 1 and 2. This wiring is
referred to as Media Dependant Interface - Crossover
(MDI-X).
When connecting a PC to a PC, or a hub port to another hub port, the transmit pair must be
exchanged with the receive pair. This exchange is done by one of two mechanisms. Most hubs
provide an Uplink switch which will exchange the pairs on one port, allowing that port to be
connected to another hub using a normal Ethernet cable. The second method is to use a crossover
cable, which is a special cable in which the transmit and receive pairs are exchanged at one of the
two cable connectors. Crossover cables are often unmarked as such, and must be identified by
comparing the two connectors. Since the cable connectors are clear plastic, it is easy to place them
side by side and view the order of the wire colors on each. On a straight-through cable, the color
order will be the same on both connectors. On a crossover cable, the orange and blue pairs will be
exchanged from one connector to the other.

Networks, Routing, and Firewall Basics
The RP614 v2 router incorporates Auto Uplink
TM
technology (also called MDI/MDIX). Each
LOCAL Ethernet port will automatically sense whether the Ethernet cable plugged into the port
should have a normal connection (e.g. connecting to a PC) or an uplink connection (e.g.
connecting to a router, 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
TM
will accommodate either type of cable to make the right connection.
Cable Quality
A twisted pair Ethernet network operating at 10 Mbits/second (10BASE-T) will often tolerate low
quality cables, but at 100 Mbits/second (100BASE-TX) the cable must be rated as Category 5
,
(Cat 5), by the Electronic Industry Association
(EIA). This rating will be printed on the cable
jacket. A Category 5 cable will meet specified requirements regarding loss and crosstalk. In
addition, there are restrictions on maximum cable length for both 10 and 100 Mbits/second
networks.

Appendix C
Preparing Your Network
This appendix describes how to prepare your network to connect to the Internet through the Model
RP614 v2 Web Safe Router and how to verify the readiness of broadband Internet service from an
Internet service provider (ISP).
Preparing Your Computers for TCP/IP Networking
Computers access the Internet using a protocol called TCP/IP (Transmission Control Protocol/
Internet Protocol). Each computer on your network must have TCP/IP installed and selected as its
networking protocol. If a Network Interface Card (NIC) is already installed in your PC, then TCP/
IP is probably already installed as well.
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.
Note:
If an ISP technician configured your computer during the installation of a
broadband modem, or if you configured it using instructions provided by your ISP, you
may need to copy the current configuration information for use in the configuration of
your firewall. Write down this information before reconfiguring your computers. Refer
to
“Obtaining ISP Configuration Information for Windows Computers
” on
page C-19
or
“Obtaining ISP Configuration Information for Macintosh Computers
” on
page C-20
for
further information.

Preparing Your 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 RP614 v2 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:
a.
