## Kubernetes Cluster Nodes
|
||||
|
||||
The required ports for cluster nodes vary across different methods for creating clusters.
|
||||
|
||||
### Hosted/Imported Kubernetes Clusters
|
||||
>**Tip:**
|
||||
>
|
||||
>If security isn't a large concern and you're okay with opening a few additional ports, you can use the table in [Commonly Used Ports](#commonly-used-ports) as your port reference instead of the comprehensive tables below.
|
||||
|
||||
The following table depicts the port requirements for [Hosted]({{< baseurl >}}/rancher/v2.x/en/cluster-provisioning/hosted-kubernetes-clusters) and [Imported]({{< baseurl >}}/rancher/v2.x/en/cluster-provisioning/imported-clusters/) clusters.

These ports are typically opened on your Kubernetes nodes, regardless of what type of cluster it is.

|

### Local Node Traffic
|
||||
|
||||
Ports marked as `local traffic` in the above requirements (e.g. `9099/tcp`) are used for Kubernetes healthchecks (`livenessProbe` and`readinessProbe`).
|
||||
These healthchecks are executed on the node itself. In most cloud environments, this local traffic is allowed by default. When you have applied strict host firewall policies on the node, or when you are using nodes that have multiple interfaces (multihomed), this traffic may get blocked. In this case, you have to explicitely allow this traffic in your host firewall, or in case of public/private cloud hosted machines (i.e. AWS or OpenStack), in your security group configuration. Keep in mind that when using a security group as Source or Destination in your security group, that this only applies to the private interface of the nodes/instances.
