Guides - Apply Firewall Rules to a Compute Instance
A free cloud-based firewall service that makes it easy to secure network traffic to and from Compute Instances.
Each Cloud Firewall can be applied to one or more Compute Instances. Use the steps below to view and modify the Compute Instances using this firewall.
Log into your Cloud Manager and select Firewalls from the navigation menu.
From the Firewalls listing page, click on the Cloud Firewall that you would like to use. This takes you to the Rules page for that firewall.
Click on the Linodes tab to see a list of all Compute Instances that are currently using this Cloud Firewall.
To add a Compute Instance to this firewall, click on the Add Linodes to Firewall button. In the form that appears, select the desired Compute Instance from the dropdown menu and click Add. Once added, all rules configured on this Cloud Firewall are applied to this Compute Instance.
To remove a Compute Instance, locate the instance within the list and click the Remove link. The rules configured on this Cloud Firewall are no longer applied to this Compute Instance and, as such, the instance may be less protected against malicious traffic or attacks.
