Create or Edit ASA Network Objects and Network Groups

An ASA network object can contain a hostname, an IP address, or a subnet address expressed in CIDR notation. Network groups are conglomerates of network objects, network groups, and IP addresses that are used in access rules, network policies, and NAT rules. You can create, read, update, and delete network objects and network groups using CDO.

Note

If cloud-delivered Firewall Management Center is deployed on your tenant:

When you create a network object or group on the Objects > FTD Network Objects or Objects > FDM Objects or Objects > ASA Objects page, a copy of the object is automatically added to the Objects > Other FTD Objects page and vice-versa. In addition, an entry is created in the Devices with Pending Changes page for each on-prem management center with Discover & Manage Network Objects enabled, from which you can choose and deploy the objects to the on-prem management center on which you want these objects.

Caution

If cloud-delivered Firewall Management Center is deployed on your tenant:

Changes you make to network objects and groups on the Objects > FTD Network Objects or Objects > FDM Objects or Objects > ASA Objects page are reflected in the corresponding cloud-delivered Firewall Management Center network object or group on the Objects > Other FTD Objects page. In addition, an entry is created in the Devices with Pending Changes page for each on-prem management center with Discover & Manage Network Objects enabled, from which you can choose and deploy the changes to the on-prem management center on which you have these objects.

Deleting a network object or group from either page deletes the object or group from both pages.
