DHCP Configuration

Use this form to set up and delete subnets, groups, IP pools, and hosts and edit DHCP entries.

To add a new entry (subnet, group, IP pool, or workstation) to the configuration or to delete an entry, select the desired action from the selection box next to the entry and click Do Action. It is not possible to add entries to pools and hosts; these can only be deleted.
Caution: When an entry is deleted, all subordinate entries are also deleted.

To edit or add DHCP options or statements in an entry, click the respective entry.

The following DHCP entries can be configured:


Subnet
This is the basic entry for the DHCP server. This entry tells the DHCP server for which subnets with which IP address masks it is responsible. All other DHCP objects can be inserted in a subnet.

Group
Host names that are handled by the DHCP server with the same DHCP parameters (options, statements) are merged to a group. Only host objects can be added to a group. However, a group can be member of the global configuration and of a subnet.

IP Pool
An address pool defines an IP address space that is to be treated differently than the other IP addresses. When the DHCP pool is created, the IP addresses in the IP pool are registered with the name server and host names are generated for these IP addresses.

Workstation
To enter a host in the DHCP configuration, the host must first be entered in the DNS configuration. A host can be added to the base configuration, to a DHCP subnet, or to a group.


Important

At least one subnet must be configured to be able to start the DHCP server.

Changes to the DHCP server are saved into the LDAP server. Click Export to create and reload the configuration of the DHCP server.
