--- title: "Coriolis Network Ports Requirements" wp_id: 40766 --- # Coriolis Network Ports Requirements In order for Coriolis to be able to perform Replica/Migration tasks, it will require network access to the Endpoints that will be used. Once the network connection is available, Coriolis will use certain ports to further communicate with the Endpoints, as it is the intermediary between the source and destination Endpoints. No direct communication is established between the source and destination endpoints, all traffic and communication go through the Coriolis Appliance. The following ports are the default for each endpoint, so the Cloud administrator must verify for any customized ports. For cloud access of the Endpoints, Coriolis will use the same ports even though the Endpoint will be used as the source or destination. The temporary worker transfer mechanism for the destination platforms offers two options: HTTPS and SSH. The default one is the **HTTPS-based transfer mechanism (TCP/5566)** , which is faster but might not work if there are firewalls in the way. The SSH-based transfer mechanism (TCP/22) is more costly but will be allowed by most firewalls since SSH access from the Coriolis installation to the temporary worker VM is always required. Coriolis automatically sets security group rules for the temporary VMs accordingly. Regarding the **temporary migration worker** for the source platforms, Coriolis uses **Replicator port 4433** for performing disk chunking and transferring the backup data to the writer located on the destination platform. This port is used on platforms that require a **migration worker machine**. ### OpenStack **Service**| **Default Port**| **Protocol** ---|---|--- Keystone| 5000| TCP Cinder| 8776| TCP Nova| 8774| TCP Glance| 9292| TCP Neutron| 9696| TCP Swift| 8080| TCP Ceph| 6789| TCP Temporary Migration Worker - Source| 22, 4433| TCP Temporary Migration Worker - Destination| 22 4433 5986 5566| TCP ### VMware **Service**| **Default** **Port**| **Protocol** ---|---|--- vSphere API Access (Management)| 443| TCP Temporary Migration Worker - Destination| 22 4433 5986 5566| TCP VM snapshot data transfer via NFC (to all ESXi nodes*)| 902| TCP * NOTE! In the case of VMware vSphere as the source platform, Coriolis must be able to connect to all the VMware ESXi nodes, not only to the one holding the VM to be migrated. That is due to how VMware manages the data transfer, refer to the VMware plugin documentation for more details. ### Amazon Web Services (AWS) **Service**| **Default** **Port**| **Protocol** ---|---|--- Public API| 80, 443| TCP Temporary Migration Worker - Source| 22, 4433| TCP Temporary Migration Worker - Destination| 22 4433 5986 5566| TCP ### Microsoft Azure **Service**| **Default** **Port**| **Protocol** ---|---|--- Public API| 80, 443| TCP Temporary Migration Worker - Source| 22, 4433| TCP Temporary Migration Worker - Destination| 22 4433 5986 5566| TCP ### Microsoft Windows Server - Hyper-V **Service**| **Default** **Port**| **Protocol** ---|---|--- Management| 443| TCP RCT Source| 6677| TCP ### Oracle Cloud Infrastructure (OCI) **Service**| **Default** **Port**| **Protocol** ---|---|--- Public API| 80, 443| TCP Temporary Migration Worker - Destination| 22 5986 5566| TCP ### oVirt (OLVM and Red Hat Virtualization) **Service**| **Default** **Port**| **Protocol** ---|---|--- Public API| 80, 443| TCP Source Image Transfer| 54322| TCP Temporary Migration Worker - Destination| 22 4433 5986 5566| TCP ### SUSE Virtualization (Harvester) **Service**| **Default** **Port**| **Protocol** ---|---|--- Kubernetes API| 443| TCP KubeVirt API| 443| TCP Temporary Migration Worker - Destination| 22 5986 5566| TCP ### SUSE Linux (KVM) **Service**| **Default** **Port**| **Protocol** ---|---|--- SSH access for libvirt qemu+ssh transport| 22| TCP Temporary Migration Worker - Destination| 22 5986 5566| TCP ### Proxmox VE **Service**| **Default** **Port**| **Protocol** ---|---|--- Management API| 8006| TCP Temporary Migration Worker - Destination| 22 4433 5986 5566| TCP ### CloudStack **Service**| **Default Port**| **Protocol** ---|---|--- Management API| 443| TCP Temporary Migration Worker - Destination| 22 4433 5986 5566| TCP ### MicroCloud/LXD **Service**| **Default Port**| **Protocol** ---|---|--- Management API| 8443| TCP Temporary Migration Worker - Destination| 22 5986 5566| TCP ### Bare-Metal (Linux p2v) **Service**| **Default Port**| **Protocol** ---|---|--- Bare-metal Hub API| 9900| TCP Snapshot Agent API| 9999| TCP ### Nutanix **Service**| **Default Port**| **Protocol** ---|---|--- Management API| 9440| TCP ### [Legacy] Oracle VM (OVM) **Service**| **Default** **Port**| **Protocol** ---|---|--- Management| 7002| TCP Temporary Migration Worker - Source| 22, 4433| TCP Temporary Migration Worker - Destination| 22 5986 5566| TCP OVM Exporter| 5544| TCP ### [Legacy] Oracle Cloud Infrastructure Classic (OCI-C) **Service**| **Default** **Port**| **Protocol** ---|---|--- Public API| 80, 443| TCP Temporary Migration Worker - Source| 22, 4433| TCP Temporary Migration Worker - Destination| 22, 5986| TCP ### Coriolis API/CLI remote access When accessing the Coriolis API or CLI from a remote / client machine, the following ports have to be allowed for the Coriolis appliance network.
