Enabling the DHCP Server
To enable the DHCP server on a particular interface, click on the appropriate tab for the
interface and check the “Enable DHCP server on interface” box.
Deny Unknown Clients
With this option selected, the DHCP server will issue IP addresses to known MAC
addresses.
Range
In the rst box, enter the starting address of your DHCP range. In the second box, enter
the ending address of the range. Note that you do not want to make this the same as the
available range, as this includes the subnet address and broadcast address, which are
unusable. Also, the address of the Cortexa interface cannot be in the range.
WINS Servers
If you use an NT 4 domain, or have pre-Windows 2000 clients that need to access an Active
Directory domain, you will need to ll in your WINS server IP addresses in these boxes. If
you only have one WINS server, leave the second box blank.
Default and Maximum Lease Time
The default lease time is the length of the DHCP lease on any clients that do not request a
specic expiration time on their DHCP lease. The default is 7200 seconds, or two hours. For
the vast majority of network environments, this is too low. We recommend setting this to one
week; 604,800 seconds.
The maximum lease time must be more than the default lease time. Most networks will not
use this value at all. In most instances, you can set this to one second longer than the default
lease time.
Click Save to save your changes, then Apply to enable the DHCP server.
