You need to create and configure the necessary DHCP deployment options in order to allow the managed DHCP Server to update Windows DNS. You can set the majority of these options at different levels in Address Manager.
To create DHCP deployment options:
- Navigate to the appropriate level in Address Manager (For example: network, DHCP ranges, or server level) that you have created for the GSS-TSIG configuration use.
- Select the Deployment options tab.
- Select New > DHCPv4 client option or New > DHCPv4 service option.
-
Create the following deployment options and values. The following client and
service options need to be configured to enable the DHCP server to update the
Windows DNS server:
DHCPv4 client options:
- Router (3)—enter IP address of the gateway. Example: 192.0.2.1 (set at network level) (client 3)
- DNS Server (6)—enter IP address of the Windows DNS server. Example: 192.0.2.100
- Default Lease Time(1)—the default lease time for an IP address. Example: 300 seconds
- Maximum Lease Time(2)—the maximum lease time for an IP address. Example: 360 seconds
- Minimum Lease Time(3)—the minimum lease time for an IP address. Example: 250 seconds
- Client Updates(4)—false
- DDNS Domain Name(5)—dhcp1.bcn.com
- DDNS Reverse Domain Name(7)—in-addr.arpa
- DDNS Updates(9)—true
- Update Static Leases(22) (optional)—if set to true, the DHCP server will send DDNS updates for static (DHCP reserved) leases. Exercise caution if enabling this option, as this option may add duplicate names if DHCP reserved hostnames are statically configured in the DNS.
