Firewalls let you control incoming network traffic to your bare metal servers and container instances by defining security rules.

​
Access Firewalls

  1. Click “Firewalls” in the left sidebar under the “Networking” section

  1. You will see the Firewalls list page showing all your firewall configurations. The Associate Bare Metal and Associated Containers columns show how many instances each firewall is attached to.

Create a Firewall

  1. Click the “Create Firewall” button in the top right corner
  2. Fill in the firewall configuration form:

​
Configuration Fields

FieldDescription
Data CenterSelect the data center where the firewall will be created
NameEnter a name for your firewall
DescriptionOptional description for the firewall

​
Inbound Rules

Inbound rules control incoming traffic to the attached instances. Each rule consists of:
FieldDescription
TypeThe type of traffic (e.g., SSH, HTTP, HTTPS, Custom)
ProtocolNetwork protocol (TCP, UDP, ICMP)
Port RangeThe port range to allow (e.g., 22-22 for SSH)
SourcesIP addresses or CIDR blocks allowed to connect (e.g., 0.0.0.0/0 for all IPs)
Click “Add Rule” to add additional inbound rules.
  1. Click “Create” to create the firewall
You can attach instances during creation, or at any time afterwards via the Manage page — see the next section.

​
Associate a Firewall with Instances

A firewall can be associated with either Bare Metal servers or Container instances. The list page shows the current counts in the Associate Bare Metal and Associated Containers columns. firewall-list-associated-containers.png
  1. On the Firewalls list page, click the firewall name (e.g., All Open) to open its detail page
  2. On the detail page, click the “Manage” button in the top right corner

  1. On the Manage page you will see two sections: Bare Metal Association and Associate to Container

  1. Click the dropdown of the section you want and select one or more instances (only instances in the same data center as the firewall are listed)

  1. Click “Save” to apply the association
The All Open preset firewall allows all inbound traffic (0.0.0.0/0) — useful for testing, but not recommended for production workloads. Use a stricter custom firewall for instances that are exposed to the internet.

​
Disassociate a Firewall from an Instance

To remove an instance from a firewall, use the same Manage page:
  1. On the Firewalls list page, click the firewall name to open its detail page
  2. Click “Manage” in the top right corner
  3. In the Bare Metal Association or Associate to Container section, locate the chip for the instance you want to disassociate and click the ”×” icon on that chip

  1. Click “Save” to apply the change
After saving, the instance’s Associated Firewall returns to whatever default applies (for example, containers fall back to the system default). The firewall itself remains allocated and can be associated with other instances.

​
Manage Firewalls

From the Firewalls list page, you can:
  • View details — click the firewall name to inspect its rules and associations
  • Edit rules — open the detail page and update inbound rules
  • Associate / Disassociate instances — use the Manage page (see above)
  • Delete firewall — from the detail page; only firewalls with no associated instances can be deleted
