How to Create High Availability with Two On-Premise Corente Service Gateways and a Corente Service Gateway in OCI Classic (Doc ID 2424465.1)

Last updated on AUGUST 04, 2018

Applies to:

Corente Cloud Services Exchange - Version 9.4 and later
Information in this document applies to any platform.


The goal of this document is to outline how to create a High Availability (HA) environment for customers that have Corente Service Gateways (CSGs) installed both on their on-premises network, and Oracle Cloud Infrastructure Classic (OCI-C). The HA configuration will be active-passive, meaning that VPN traffic will traverse the primary VPN tunnel, unless the primary VPN tunnel no longer becomes available. The traffic will then traverse the secondary VPN tunnel until connectivity on the primary VPN tunnel is restored.

NOTE: The general use case for this method is to connect two CSGs that are on the same on-premises network(s) to the OCI-C CSG, generally through two separate ISPs or separate data paths.


NOTE: This method only works when Corente Service Gateways are used to build a VPN connection between the on-premises network and Oracle Cloud Infrastructure Classic. This method does NOT work with any Corente Service Gateway to Third Party Device (ex. Cisco, Checkpoint, Palo Alto, etc.) VPN connections, nor does this method work for VPN as a Service.
