# Edit the Greenfield Rule

> Edit or delete the default Greenfield Distributed Cloud Firewall rule

The first time you use Distributed Cloud Firewall (DCF), a Greenfield Rule is
created automatically to prevent traffic from being dropped before you start
configuring the rest of your rules.

To edit the Greenfield Rule, click the pencil icon next to the rule. You can
edit the following fields and click *Save in Drafts*.

* Source and Destination SmartGroups
* Protocol
* Action: Deny or Accept
* Enforce: On/Off
* Logging: On/Off
* Rule Priority

When you are ready to commit the rule, click *Save*.

## Delete the Greenfield Rule

You can delete the Greenfield Rule after creating other DCF rules.
