this is the central config file, not a lot to say about it really, except the usage of the GATEWAYDEV parameter. This param is to be used when multiple network gateways exist on a RHEL server. But in a simple setup, you'd just see GATEWAY=IP ADDRESS in use.
| Option | Variable(s) | Note |
|---|---|---|
| NETWORKING | yes/no | |
| NETWORKING_IPV6 | yes/no | |
| HOSTNAME | hostname | The FQDN of the server |
| GATEWAY | ip address | Use this, if server has a single GW |
| GATEWAYDEV | device name | Use this, if server has multiple GWs (e.g. eth1) |
