Update Firewall rules of a Network Security Group

Note: Only contract administrators, owners, and users with permissions to the VDC concerned can create and manage NSGs via API.

Prerequisite: You need an IONOS Cloud account with API credentials configured with the appropriate permissions.

To update a firewall rule of a NSG, you need to use the following Cloud API PUT or PATCH request providing the datacenterId, securityGroupId and ruleId:

PUT /datacenters/{datacenterId}/securitygroups/{securityGroupId}/rules/{ruleId}

PATCH /datacenters/{datacenterId}/securitygroups/{securityGroupId}/rules/{ruleId}
