Starting with VMware Cloud Director 10.5.1, you can configure firewall rules on your provider gateway that uses IP spaces.

Prerequisites

• Verify that the provider gateway is using IP spaces.
• Verify that the provider gateway is private, i.e. that it is dedicated to a single orgnization.
• Verify that the NAT and Firewall Service Intentions of the provider gateway is set to Provider Gateways or to Provider and Edge Gateways.
• Verify that your role includes the Provider Gateway Firewall: View and Provider Gateway Firewall: Manage rights.
• Verify that the backing NSX tier-0 router is in active-standby mode. Otherwise, you won't be able to set the NAT and Firewall Service Intentions of the provider gateway to Provider Gateways or to Provider and Edge Gateways.
