When you select SSH, the
Add Rule dialog will change to display only those fields that are required to define a rule that allows an SSH connection (see Figure 5.2). Use the fields to specify your connection preferences:
•

Use the Remote drop-down listbox to specify the type of traffic that will be allowed to connect via this rule. The connection options for an SSH rule are CIDR and Security Group; the default is CIDR.

Use the CIDR field to specify who may connect via the new rule:

If you selected CIDR, provide the CIDR-formatted address or addresses that are allowed to connect to the server via ssh. By default, the OpenStack console displays the address

22 for connections from any host.
If you selected Security Group, use the
Security Group and
Ether Type drop-downs to make the appropriate system-specific selections.
