High Availability

  • Multinode High Availability features in private clouds (vSRX Virtual Firewall)—vSRX Virtual Firewalls deployed in private clouds (KVM and VMware ESXi) support following features:

    • ICL encryption—Uses IPsec protocols to secure synchronization messages between high-availability nodes, ensuring data privacy.
    • Flexible datapath failure detection—Offers path monitoring with granular control through weighted features, supporting IP, BFD, and interface monitoring.

    You can configure these features on vSRX instances using the same method as for physical SRX Series firewalls.

    See [Multinode High Availability Support for vSRX Virtual Firewall Instances.]

  • MNHA support for Google Cloud Platform (vSRX Virtual Firewalls)—You can configure a pair of vSRX instances on the Google Cloud Platform (GCP) Marketplace for an active/backup Multinode High Availability setup. This configuration enhances reliability and efficiency of high availability operations on GCP, ensuring uninterrupted services for users.

    [See Multinode High Availability in Google Cloud Platform.]

  • IPsec VPN tunnels support for Multinode High Availability on AWS and Azure Cloud (vSRX3.0)— IPsec VPN support is available for active/backup Multinode High Availability in AWS and Azure Cloud deployments.

    IPsec VPN tunnels are secure, encrypted connection between different networks or endpoints. In the Multinode High Availability setup, the system establishes secure tunnels between the nodes in high availability setup and VPN peer devices.
