NexGen Cloud Firewalls API

A firewall is a set of inbound and outbound rules scoped to an environment. Attach a firewall to one or more virtual machines or Kubernetes clusters to control which network traffic each resource can send and receive. Default rules block all inbound traffic, add explicit allow rules for SSH, HTTP, or any service you need to expose.
