2. Specify the settings in the DHCP Settings table:
• Enable Server. This check box enables or disables the feature of DHCP
server. If you enable this feature, the Qube 3 automatically provides the
network configuration information to a client machine when you power
up the client machine.
• Client Domain Name. Enter the domain name that the Qube 3 will
automatically serve to these clients. This domain name is usually the
same as the domain name of your Qube 3. Enter only lowercase
alphanumeric characters, dashes or periods. For example, cobalt.com is
a valid entry.
• Client DNS Address. Enter the IP address or addresses of your local
DNS server or servers that the Qube 3 will automatically serve to these
clients. A DNS server translates text-based host names and domain
names into numeric IP addresses and vice-versa. Enter a series of four
numbers between 0 and 255 separated by periods. For example,
192.168.10.10 is a valid entry.
For more information on DNS, see Appendix E, “Domain Name
System”.
• Client Subnet Mask. Enter the subnet mask that the Qube 3 will
automatically serve to these clients. Enter a series of four numbers
between 0 and 255 separated by periods. For example, 255.255.255.0 is
a valid entry.
• Client Default Gateway. Enter the IP address of your local network
gateway that the Qube 3 will automatically serve to these clients. A
network gateway allows you to connect to the world outside of your local
network. Enter a series of four numbers between 0 and 255 separated by
periods. For example, 192.168.10.10 is a valid entry.
• Maximum Lease Time. The networking information assigned by a
DHCP server expires after a fixed period of time. Enter the maximum
period of time in seconds before a lease expires. Enter an integer greater
