Info
This section describes firewall policies in private cloud with network managers (NSX, NSX-T) and in public cloud (AWS, Amazon, OCI), and firewall rules in Google Cloud Platform. For details of classic firewalls (Edge firewalls in orgVDC in vCloud Director), see Manage classic firewalls .

Introduction to firewalls

...

Go to Virtual datacenters → Network → Firewalls
1. For GCP go to Global → Network → Firewalls
Click the Add button
Enter the firewall details
1. In GCP, if you assign a firewall to a Virtual datacenter, you can then use it as a default firewall
2. In VCD, if you do not select a Virtual datacenter, the platform will create the firewall in the platform only, not in the provider

Select the Inbound or Outbound tab for the traffic direction you wish to control
Enter the details of a rule
1. Protocol
  - Select from Common protocols, OR
  - Select and enter a Custom protocol
2. Port range with the Start port and End port that this rule will apply to.
  To enter one port, enter the same value twice, or optionally apply the rule to a number of ports at the same time.
  For Azure and GCP, you can enter:
  1. a single port, such as 80
  2. a range, such as 1024-65535
  3. a list of port/range, such as 80,1024-65535
3. Sources or Targets as a network address and netmask, or a comma separated list of these (with no spaces)
Click Add. The firewall rule will be added to the Firewall rules list
Enter more rules as required, then click Save

Excerpt

name	Create a firewall policy in GCP

In GCP, the platform can create firewall rules in virtual datacenters or in global networks, to later attach to VMs.

Panel
Privileges: Manage firewall, Manage global networks

To create a new firewall, do these steps:

Go to Virtual datacenters → Network → Firewalls OR
Go to myCloud → Global → select the GCP provider → Network → Firewalls
Click the Add button
Enter the firewall details and select the direction
1. For the Name, see GCP the Google cloud entity naming conventions. See Google Cloud Platform integration
2. For the Direction, select INGRESS for incoming traffic or EGRESS for outgoing traffic
3. For Sources or Targets, enter a list of comma separated values in CIDR format
4. For Priority, the default is 1000 and lower numbers have higher priority
Go to Inbound or Outbound and add firewall rules
1. Optionally, select from predefined Common protocols OR
  Enter Protocols and enter a list of Ports, separated by commas, and/or a port range, separated with a dash (e.g. 80,8000-8009)
After you finish adding rules, click Save

The platform will create your firewall in the provider.
