## Configuring Network Connectivity

The simplest way to deploy Talos is by ensuring that all the remote components of the system (`talosctl`, the control plane nodes, and worker nodes) all have layer 2 connectivity.
This is not always possible, however, so this page lays out the minimal network access that is required to configure and operate a talos cluster.

> Note: These are the ports required for Talos specifically, and should be configured _in addition_ to the ports required by kuberenetes.
> See the [kubernetes docs](https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/install-kubeadm/#check-required-ports) for information on the ports used by kubernetes itself.
