2-3 LAN
To set the LAN's IP Address.
2-3-1 LAN Settings
The default value is 192.168.0.1 for the IP address and 255.255.255.0 for
the Subnet Mask. You may change the value according to your needs.
To enable the DHCP server to allocate dynamic IP addresses to the clients
PCs, click "Enable". The client can get an IP Address that is between the
IP Pool Starting Address and the IP Pool Ending Address. You may also
change the IP Pool range value.
You can enter your local domain name in the Local Domain Name fields.
2-3-2 DHCP Client List
The DHCP client list allows you to see which clients are connected to the
router via IP address, host name, and MAC address.
The Lease Time is the amount of time a
network user will be allowed to connect
to the Router with his/her current
dynamic IP address. Enter the amount
of time, in hours, days or weeks, which
the user will be "leased" this dynamic
IP address.

2-4 NAT
Network Address Translation (NAT) allows multiple users at the local site
to access the Internet through a single public IP address. NAT can also
prevent hacker attacks by mapping local addresses to public addresses for
key services such as the Web or FTP.
2-4-1 Special Application
Some applications require multiple connections, such as Internet gaming,
video conferencing, and Internet telephony. These applications cannot
work when Network Address Translation (NAT) is enabled. When users
send this type of request to your network via the Internet, the Router will
forward those requests to the appropriate PC. If you need to run
applications that require multiple connections, specify the port normally
associated with an application in the "Trigger Port" field, select the
protocol type as TCP or UDP, then enter the public ports associated with
the trigger port to open
•
TCP (Transmission Control Protocol) - A method (protocol) used
along with the Internet Protocol (Internet Protocol) to send data in the
form of message units between computers over the Internet. While IP
takes care of handling the actual delivery of the data, TCP takes care
of keeping track of the individual units of data (called packets) that a
message is divided into for efficient routing through the Internet.
•
UDP (User Datagram Protocol) - A communications method
(protocol) that offers a limited amount of service when messages are
exchanged between computers in a network that use the Internet
Protocol (IP). UDP is an alternative to the TCP and, together with IP,
is sometimes referred to as UDP/IP. Like the Transmission Control
Protocol, UDP uses the Internet Protocol to actually get a data unit
(called a datagram) from one computer to another. Unlike TCP,
however, UDP does not provide the service of dividing a message
into packets (datagrams) and reassembling it at the other end.
