from a range from IP Pool Starting Address to IP Pool Ending
Address, also, you can change the IP Pool range value.
The Lease Time is the amount of time a network user will be allowed
connection to the Router with their current dynamic IP address. Enter
the amount of time, in hours, days or weeks, which the user will be
ìleasedî this dynamic IP address.

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 Barricade via IP address, host name, and MAC 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, Internet telephony and others. 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 them for inbound
traffic.
