assigned with a private IP address with default value of 192.168.1.2 to 192.168.1.254.
These PCs are not accessible by the outside word but they can communicate with the
outside world through the public IP 168.111.1.1.
Private IP Address
Private IP addresses are also LAN IP addresses, but are considered “illegal” IP addresses to
the Internet. They are private to an enterprise while still permitting full network layer
connectivity between all hosts inside an enterprise as well as all public hosts of different
enterprises.
The Wireless Broadband Router uses private IP addresses by assigning them to the LAN that
cannot be directly accessed by the Internet or remote server. To access the Internet, private
network should have an agent to translate the private IP address to public IP address.
RIP (Routing Information Protocol)
RIP is a routing protocol that uses the distance-vector routing algorithms to calculate
least-hops routes to a 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.
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.
UDP (User Data gram Protocol)
UDP is a connectionless transport service that does not own the reliability services provided
by TCP. UDP gives applications a direct 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.
