Add the required ports when installing Cortex XSOAR On-prem.
The following ports are required for standalone (one VM) and a three-node cluster (three VMs).
Port | Protocol | Purpose |
---|---|---|
22 | TCP | SSH communication |
8880 | TCP | Node communication |
Required control plane ports
A Kubernetes cluster consists of a control plane and one or more worker nodes. For Cortex XSOAR, in standalone (one VM), the VM acts as both control plane and as a worker node. In multi-node clusters, the first three nodes act as both control plane and as worker nodes, and any additional node added acts as a worker node.
The following ports are required for a control plane.
Name | Port | Protocol |
---|---|---|
etcd client port | 2379 | TCP |
etcd peer port | 2380 | TCP |
Kubernetes API | 6443 | TCP |
Kubelet API | 10250 | TCP |
kube-scheduler | 10257 | TCP |
kube-controller-manager | 10259 | TCP |
Required worker node port
The following port is required for a worker node.
Name | Port | Protocol |
---|---|---|
kube nodeport range | 30000:32767 | TCP |
Intra-node communication
The following port is required for a multi-node cluster (three or more VMs).
Name | Port | Protocol |
---|---|---|
Calico with IPv4 Wireguard | 51820 | UDP |
