VPN Interoperability Guides

This page provides interoperability guides and vendor-specific notes for on-premises third-party VPN devices or services you can use to connect to Cloud VPN.

Each Interop guide offers specific instructions for connecting the third-party VPN solution to Cloud VPN.

If the third-party solution supports dynamic (BGP) routing, the guide includes configuration instructions for Cloud Router.

Interop guides by vendor

This section lists interoperability guides by vendor in alphabetical order. Each guide covers how to use that vendor's VPN gateway solution with Cloud VPN.



Vendor-specific notes


  • If your VPN gateway runs Cisco IOS XE, make sure you're running version 16.6.3 (Everest) or later. Earlier versions have known problems with Phase 2 rekey events, which results in tunnels going down for a few minutes every few hours.

  • When using Cisco ASA devices with a Cloud VPN tunnel, you cannot configure more than one IP address range (CIDR block) for each of the local and remote traffic selectors. This is because Cisco ASA devices use a unique Security Association (SA) for each IP address range in a traffic selector, while Cloud VPN uses a single SA for all IP ranges in a traffic selector. See traffic selectors for more information.
