Understanding Firewalls

Firewall or security group rules manage incoming traffic to your instances. You can create global firewall policies (containing rules) on the Firewall page under Utilities dropdown in sidebar and attach them to your preferred cloud provider. The rules then apply to all instances within that provider.

---

Create a Firewall Policy and rules:

1. Go to global Firewall in the Zeus dashboard and add a new policy.

2. Under Inbound Rules, click Edit.

3. Choose a rule type:

   • Custom TCP/UDP: Manually configure specific traffic.

   • HTTPS/SSH: Automatically allow secure traffic.

   • All TCP/UDP: Allow all traffic for the protocol.

4. In Source, enter an IP or range (e.g., 203.0.113.0/24 or 0.0.0.0/0 to allow all).

5. For Custom TCP/UDP, specify a port (e.g., 8080 or 8080-8081).

6. (Optional) Add a description.

7. Click Update to save.

To Update a Rule:

1. Navigate to Firewall > Inbound Rules > Edit.

2. Modify the desired rule.

3. Click Update.

Note: You can also update rules via the Zeus API.

To Delete a Rule:

1. Go to Firewall > Inbound Rules > Edit.

2. Click ❌ next to a rule.

3. Click Update.

Warning: Configure rules properly as this may prevent new instances from launching. Deleting a rule for TCP/22 (SSH) may block access to your Linux based instances.

Other ways to manage rules:

Visit the Firewall page in the dashboard or use the Zeus API to list or manage existing rules.
