Manage firewalls

Introduction to firewalls

The platform provides a unified interface to firewalls in varied cloud environments. 

This section describes firewall policies, which are similar to security groups.

Abiquo firewall policies represent.

• AWS security groups

• Azure firewall policies

• GCP firewall rules

• OCI network security groups

For more details, please see the public cloud features table for each provider.

Synchronize firewall policies with the cloud provider

The synchronization process will onboard firewalls and it will update the platform's information about firewalls that already exist in the cloud provider. The platform synchronizes automatically when you onboard virtual resources from public cloud. Depending on the provider, the platform may support synchronization at the level of the location (public cloud region) or virtual datacenter.

To synchronize firewalls do these steps:

1. In the myCloud view go to Virtual datacenters, or Locations, or for Google Cloud Platform select the Global view

2. Go to Network → Firewalls

3. Click the double-arrow synchronize button 

To synchronize a firewall in AWS before you add new firewall rules:

1. 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:

1. Go to Virtual datacenters → Network → Firewalls

   1. For GCP go to Global → Network → Firewalls

2. Click the Add button

3. 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

      Open

      

      Create a firewall in AWS

4. Click Save to create the firewall

5. Add Firewall rules as describe in Create firewall rules.

Edit firewall rules

You can edit firewall rules after you create a firewall.

See https://abiquo.atlassian.net/wiki/spaces/doc/pages/441123132

Create a firewall policy in GCP

Set a firewall policy as the default for a virtual datacenter

You can set a default firewall policy for each virtual datacenter. 

To set or unset a default firewall for a virtual datacenter:

1. Select the firewall

2. Click the star default firewall button

Open

Set a firewall policy as the default

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. 

Edit a firewall policy

If your provider allows it, you may edit a firewall policy in the platform. 

To edit a firewall policy:

1. Go to Virtual datacenters → select virtual datacenter OR
   select a region → Network → Firewalls

2. Select the firewall policy and click the pencil edit button.

   1. 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.

   2. If you select the Default option, the platform will assign this firewall to new VMs.

3. Make your changes and click Save

Add tags to a firewall policy

When you edit a firewall, you can add tags to group resources. You can then go to Control view to manage tagged resources.

To manage tags for a firewall, edit the firewall, go to Tags, and add tags.

For more details, see .

Move a firewall policy to another virtual datacenter

Before you begin:

1. 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

1. Go to Virtual datacenters → Locations or Global

2. Select the public cloud region, or Azure provider and resource group

3. Edit the firewall policy and select the new Virtual datacenter

Display firewall policies

You can display and manage firewalls in the platforms at the level of the virtual datacenter or the location (public cloud region or datacenter).

To display firewalls in a virtual datacenter in a provider:

1. Go to Virtual datacenters → select a virtual datacenter → Network → Firewalls

To display all firewalls in Google Cloud Platform

1. Go to myCloud → Global view

2. Select the GCP provider → Networks → Firewalls

To display all firewalls in a location (public cloud region or datacenter):

1. Go to Cloud virtual datacenters view → Locations

2. Select a location

3. Go to Network → Firewalls

    

   Firewalls that do not exist in the provider are grayed out, and you should delete these firewalls.

To display firewalls in an Azure Resource Group:

1. Go to Cloud virtual datacenters view

2. Go to Global → Azure → Resource Groups

3. Select a resource group

4. To display the details of the firewall, edit the firewall

Assign a firewall policy to a VM

See .

Delete firewall policy rules

To delete firewall rules, do these steps.

1. Go to Virtual datacenters → select a virtual datacenter OR
   select All → Network → Firewalls

2. Edit the firewall

3. Select the Inbound or Outbound tab

4. On the left-hand side of each rule you wish to delete, click the trash bin Delete button

5. Click Save

Delete a firewall policy

To delete a firewall policy:

1. Edit each VM that is using the firewall policy to remove the firewall policy

2. Select the firewall policy

3. Click the Delete button
