OpenVPN Server Requirements

The Open VPN server is provided as a virtual machine disk image formatted for use with VMWare's vSphere Hypervisor (also known as ESXI). VMware vSphere Hypervisor is a free platform for running a virtual machine on an applications server (available here). 

Virtual Machine Hypervisor Requirements

The virtual machine where OpenVPN Server runs requires the following resources on a hardware applications server:

  • Minimum one 64-bit processor core that includes Intel VT-X or AMD RVI support.
  • 4 GB RAM (required by VMware vSphere Hypervisor version 5.5)
  • 20 GB hard drive space

Detailed specs can be found at VMWare's site (VMWare 5.5). VMWare specs are generally sized for large-scale production environments where hardware will support many VMs. Take that into consideration when reviewing the complexity of VMWare requirements.

Network Requirements

  • Public IP Address port-forwarded to OpenVPN Server, using Port 1194 UDP.
  • Routing in the network default gateway to the VPN phone subnet.
  • The Wave Server and the OpenVPN server should be on same subnet.
