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. |
Introduction to firewalls
...
To synchronize firewalls do these steps:
In the myCloud view go to Virtual datacenters, or Locations, or for Google Cloud Platform select the Global view
Go to Network → Firewalls
Click the double-arrow synchronize button
To synchronize a firewall in AWS before you add new firewall rules:
Select the firewall and click the double-arrow synchronize button
...
Create a firewall policy
The platform can create firewall policies in virtual datacenters in the provider, or in the platform only, for later use in providers, depending on provider support.
...
To create a new firewall, do these steps:
Go to Virtual datacenters → Network → Firewalls
For GCP go to Global → Network → Firewalls
Click the Add button
Enter the firewall details
In GCP, if you assign a firewall to a Virtual datacenter, you can then use it as a default firewall
In VCD, if you do not select a Virtual datacenter, the platform will create the firewall in the platform only, not in the provider
...
Click Save to create the firewall
Add Firewall rules as describe in Create firewall rules.
...
Edit firewall
...
rules
You can define edit firewall rules for inbound and outbound traffic in your firewall policy.
To add a new firewall rule:
Select the virtual datacenter or location
Select the firewall
On the Firewall rules panel, click the pencil Edit button
Select the Inbound or Outbound tab for the traffic direction you wish to control
Enter the details of a rule
Protocol
Select from Common protocols, OR
Select and enter a Custom protocol
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:a single port, such as
80a range, such as
1024-65535a list of port/range, such as
80,1024-65535
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

Create a firewall policy in GCP
| Excerpt | ||

In GCP, the platform can create firewall rules in virtual datacenters or in global networks, to later attach to VMs.
To create a new firewall, do these steps:
|
...
|
...
Go to Inbound or Outbound and add firewall rules
For more details see GCP firewall policy rules table below

After you finish adding rules, click Save

Virtual datacenter
...
Optionally select a virtual datacenter. This option is useful in recommending firewalls for your users and to enable you to set a default firewall. If you do not select a virtual datacenter, the platform will still create the firewall in the provider and users can still attach this firewall to their VMs

Set a firewall policy as the default for a virtual datacenter
...
To set or unset a default firewall for a virtual datacenter:
Select the firewall
Click the star default firewall button
...
When the user creates a VM, the platform will assign the default firewall. The firewall rules apply to VMs, not individual NICs on the VMs. Changes to the firewall ruleset will apply to every VM in the virtual datacenter with the default firewall. If you do not set a default firewall but the provider requires one, for example, AWS, the platform will set the provider's default firewall. In AWS the default firewall is not marked.
...
To edit a firewall policy:
Go to Virtual datacenters → select virtual datacenter
...
OR
select a region → Network → FirewallsSelect the firewall policy and click the pencil edit button.
In GCP only, optionally select a virtual datacenter. You can use this option to recommend firewalls for your users.
If you do not select a virtual datacenter, the firewall will still exist in the provider and users can still attach this firewall to their VMs.If you select the Default option, the platform will assign this firewall to new VMs.

Move a firewall policy to another virtual datacenter
Before you begin:
Check if your provider allows you to move firewalls. For example, Azure ARM allows you to move firewalls to other VDCs in the same resource group
To move a firewall to another virtual datacenter
Go to Virtual datacenters → Locations or Global
Select the public cloud region, or Azure provider and resource group
Edit the firewall policy and select the new Virtual datacenter
...
Display firewall policies
...
To display firewalls in a virtual datacenter in a provider:
Go to Virtual datacenters → select a virtual datacenter → Network → Firewalls
...
To display all firewalls in Google Cloud Platform
Go to myCloud → Global view
...
Select the GCP provider → Networks → Firewalls
To display all firewalls in a location (public cloud region or datacenter):
Go to Cloud virtual datacenters view → Locations
Select a location
Go to Network → Firewalls
...
Firewalls that do not exist in the provider are grayed out, and you should delete these firewalls.
| Tip |
|---|
To filter firewalls, enter text in the Search box to search by the Name, Description, and Provider ID in the Firewalls list. |
...
To display firewalls in an Azure Resource Group:
Go to Cloud virtual datacenters view
Go to Global → Azure → Resource Groups
...
Select a resource group
To display the details of the firewall, edit the firewall

Assign a firewall policy to a VM
...
To delete firewall rules, do these steps.
Go to Virtual datacenters → select a virtual datacenter
...
OR
select All → Network → FirewallsEdit the firewall
Select the Inbound or Outbound tab
On the left-hand side of each rule you wish to delete, click the trash bin Delete button
Click Save
...
Delete a firewall policy
To delete a firewall policy:
Edit each VM that is using the firewall policy to remove the firewall policy
Select the firewall policy
Click the Delete button
| Excerpt | ||
|---|---|---|
| ||
In private cloud with NSX-T, you can delete network resources by deleting the virtual datacenters. The platform will automatically remove VMs, virtual appliances, load balancers, public IPs, and firewalls from the virtual datacenter. The firewalls will remain in the enterprise and you can reuse them. When you delete a virtual datacenter, public IPs that are not used by VMs will remain in the provider and the synchronization process will delete them. |
