Adding multiple clients to Cyber Defense Manager (CDM) firewall policy
Host can be added at a time from each firewall rule in a Firewall policy. To eliminate the retyping of each host address or host name for each firewall rule, create a single host group with multiple hosts.
A host group is accessible from any firewall rule in any Firewall policy. Any changes made to the host group update automatically in the Firewall policies that refers the group.
When a host group is added to a firewall rule, it adds all the hosts as a single entry. Hosts can be removed from each firewall rule when it is not needed anymore
To delete the host group from all firewall policies, the group's host address or names get converted to multiple entries in the firewall rule. For example, if a host group has five items, the host group coverts from one entry to five entries in each firewall rule.
To create host groups
When a host group is updated, each Firewall policy that refers the host group gets updated automatically and a new policy version is created.
To add host groups to a firewall rule
Select Add from Host Group, check a host group in the Group Name column, and select Submit > Submit.
