1. Objectives

In SDN solutions, some services are provided by the SDN, for example

  • Source NAT
  • Static NAT
  • Load Balancer
  • Port forwarding
  • Network ACL (VPC)
  • Firewall rules (Isolated network)

However, there are still some services which are not supported by the SDN provider, for example

  • Dhcp (supported by some SDN providers)
  • Dns (supported by some SDN providers)
  • UserData (it is unsupported by SDN providers)
  • Vpn

In this case, CloudStack VR is used for provide Dhcp/Dns/Userdata services to the vm instances. It is not in the path of the traffic, it acts as a helper vm

The goal of this feature is to support VPNs in Cloudstack VR

  • Remote access VPN for SDN networks 
  • Site-to-Site VPN for SDN networks
