FortiOS 6 – IPSEC One-Click VPN (OCVPN)
One-Click VPN (OCVPN)
One-Click VPN (OCVPN) is a cloud-based solution that greatly simplifies the provisioning and configuration of IPsec VPN. The administrator enables OCVPN with a single click, adds the required subnets, and then the configuration is complete. The OCVPN updates each FortiGate automatically as devices join/leave the VPN, as subnets are added/removed, when dynamic external IPs change (e.g. DHCP/PPPoE), and when WAN interface bindings change (as in the dual WAN redundancy case).
Configuration changes and events are automatically propagated across participating nodes without user intervention, so in a sense, the VPN manages itself as a unit with only bare minimum user input. The user specifies which subnets to participate in the VPN. Everything else happens transparently to the user.
After registering devices with FortiCare, devices use SSL to register local subnets with the OCVPN cloud service at https://productapi.fortinet.com. The WAN IP is determined automatically (devices must use a publicly routed external WAN IP address) and the gateway IP address and participating subnets are uploaded to a cloud repository that collects and stores the information in each customer’s FortiCare account.
The following limitations apply to FortiOS OCVPN:
l The FortiGate must be registered with a valid FortiCare Support license. l Only full-mesh VPN configurations using PSK cryptography are supported. l Public IPs must be used (FortiGates behind NAT cannot participate). l Non-root VDOMs and FortiGate VMs are not supported. l Up to 16 nodes can be added to the OCVPN cloud, each with a maximum of 16 subnets.
OCVPN support for High Availability (HA)
As of 6.0.2, HA-enabled devices are now supported by OCVPN.
Prior to establishing the HA cluster, if OCVPN is in use then both devices should be registered to the
OCVPN cloud service. During failover, the old serial number is withdrawn and a new serial number (and VPN) is added, to account for the change in status.
