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.

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

You can delete the Greenfield Rule after creating other rules.
