If your provider offers firewall policies, first create them in your virtual datacenters, then assign firewall policies to your VMs.
To assign a firewall from the virtual datacenter to a VM:
- Go to Virtual datacenters → edit VM → Firewalls
- Mark the required firewall policy with a tick in the Firewall policies checklist
- Click Save or continue editing the VM as required
- If you cannot assign more firewall policies, check your cloud provider's limit. For example, for AWS, see http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_SecurityGroups.html#VPCSecurityGroups
- If your provider's default firewall policy does not display, you may need to synchronize your virtual datacenter or firewall policies before you continue
- If an expected firewall policy does not display, for example, a firewall policy that you recently created, you may need to wait for the firewall policy to propagate through the provider's API because of eventual consistency
- You can remove the default firewall when editing a VM. However, if the provider requires a firewall and you do not supply another one, the platform will assign the default firewall again.
