If your environment does not include vCenter Server, clients can connect directly to the ESXi network.
You can connect to a standalone ESXi host in several ways.
- VMware Host Client
- ESXCLI interface
- vSphere Web Services SDK or vSphere Automation SDKs
- Third-party clients
- Use a firewall to protect your ESXi layer or, depending on your configuration, your clients, and the ESXi layer. This firewall provides basic protection for your network.
- Licensing in this type of configuration is part of the ESXi package that you install on each of the hosts. Because licensing is resident to ESXi, a separate License Server with a firewall is not required.
You can configure firewall ports using ESXCLI or using the VMware Host Client. See vSphere Single Host Management - VMware Host Client.
