Concepts

• Floating IPs: The Network service (OpenStack Neutron) implements floating IPs as public addresses you attach to an instance on a private network when you need reachability from the internet or another external...
• IP Address Management: Instances on Quake AI receive at least one private IP address from the subnet they connect to. How that address is allocated, how it reaches the guest OS, and what happens when you need multiple...
• Networks: Networks are isolated Layer 2 segments that give your instances connectivity. Instances attach to at least one network; most production deployments use private networks with routers and floating IPs...
• Ports: The Network service (OpenStack Neutron) implements ports as the logical attachment between a network and a device, most often a VM’s virtual NIC, but also router interfaces and other integrations...
• Routers: The Network service (OpenStack Neutron) implements routers as virtual layer-3 gateways inside your project. They connect private subnets to each other and, when you set an external gateway, to...
• Security Groups: The Network service (OpenStack Neutron) implements security groups as stateful packet filters attached to instance ports. Each rule describes allowed traffic by direction (ingress or egress), IP...
