destination. It is used on the Internet
and is common in the NetWare
environment. It exchanges routing
information with other routers. It
includes V1, V2 and V1&V2, which
controls the sending and receiving of
RIP packets over Ethernet.
interface with IP and the ability to
address a particular application
process running on a host via a port
number without setting up a
connection session.
Virtual Server
You can designate virtual servers,
e.g., a FTP, web, telnet or mail server,
on your local network and make them
accessible to the outside world. A
virtual server means that it is not a
dedicated server -- that is, the entire
computer is not dedicated to running
on the public network but in the
private network.
Infrastructure mode
A backbone to extend the service
provided by network. This mode
provides wireless connectivity to
multiple wireless network devices
within a fixed range or area of
coverage, interacting with wireless
nodes via an antenna.
SSID
SSID is a thirty-two
character(maximum) alphanumeric
key identifying the wireless local area
network.
Service Set Identity. A group name
shared by all members of an IEEE
802.11b network. Only devices with
the same SSID are allowed to
establish connections. For the
wireless devices in a network to
communicate with each other, all
device must be configured with the
same SSID.
MAC Address
Media Access Code Address. A
unique, 48-bit number assigned to
every network interface card by the
manufacturer.
NAT (Network Address
Translation) IP Address
NAT is an Internet standard that
translates a private IP within one
network to a public IP address, either
a static or dynamic one. NAT
provides a type of firewall by hiding
internal IP addresses. It also enables a
company to use more internal IP
addresses.
If the IP addresses given by your ISP
are not enough for each PC on the
LAN and the Broadband Home
Router, you need to use NAT. With
NAT, you make up a private IP
network for the LAN and assign an
IP address from that network to each
PC. One of some public addresses is
configured and mapped to a private
workstation address when accesses
are made through the gateway to a
public network.
For example, the Broadband Home
Router is assigned with the public IP
address of 168.111.2.1. With NAT
enabled, it creates a Virtual LAN.
Each PC on the Virtual LAN is
assigned with a private IP address
with default value of 192.168.0.2 to
192.168.2.254. These PCs are not
accessible by the outside word but
they can communicate with the
outside world through the public IP
168.111.2.1.
