7.3. Required firewall settings
An IP address range for the node network must be enabled during firewall configuration. You can use the default values or customize the IP address range. If you choose to customize the node network IP address range from the default 10.42.0.0/16 setting, you must also use the same custom range in the firewall configuration.
| IP Range | Firewall rule required | Description |
|---|---|---|
| 10.42.0.0/16 | No | Host network pod access to other pods |
| 169.254.169.1 | Yes | Host network pod access to Red Hat build of MicroShift API server |
