Figure 5.1. DHCP Server Objects
The following sections discuss these two DHCP server options.
5.3.1. Static IPv4 DHCP Hosts
Where the administrator requires a fixed relationship between a client and the assigned IP
address, NetDefendOS allows the assignment of a given IP to a specific MAC address. In other
words, the creation of a static host.
Static Host Parameters
Many such assignments can be created for a single DHCP server and each object has the
following parameters:
Host This is the IP address that will be handed out to the client.
MAC Address This is the MAC address of the client. Either the MAC address can be
used or the alternative Client Identified parameter can be used.
Client Identified If the MAC address is not used for identifying the client then the client
can send an identifier in its DHCP request. The value of this identifier
can be specified as this parameter. The option exists to also specify if
the identifier will be sent as an ASCII or Hexadecimal value.
Example 5.3. Static IPv4 DHCP Host Assignment
This example shows how to assign the IPv4 address 192.168.1.1 to the MAC address
00-90-12-13-14-15. The example assumes that the DHCP server DHCPServer1 has already been
defined.
Command-Line Interface
1. First, change the category to the DHCPServer1 context:
gw-world:/> cc DHCPServer DHCPServer1
2. Add the static DHCP assignment:
gw-world:/DHCPServer1> add DHCPServerPoolStaticHost
