All network traffic is blocked in OpenStack by default. You need to explicitly grant access to individual services by utilising Security Groups. This is similar to setting up firewall rules on your router or server. If setup correctly, you can access your virtual machine via SSH connection from your terminal.[^2]

Instances in OpenStack make use of user-defined internal networks, through which they can communicate. To access your instances from an external network, you need to connect the internal and the external network via a virtual router and allocate a public \(floating\) IP address to your virtual machine.
By logging in, you are automatically provided with a default internal network **"internal-net"** and a default virtual router that connects to the public network **"public-float-21"**with a subnet of **192.168.0.0/24.**In order to make your instance publicly accessible, you only need to assign a public IP to it.
