Aviatrix release 6.0 introduced Firewall Instances Health Check Enhancement. This enhancement checks a firewall instance’s health by pinging its LAN interface from the connecting Aviatrix FireNet gateway. An alternative option to check health through firewall’s management interface. ICMP health check to the Firewall LAN interface improves firewall failure detection time and detection accuracy.
This enhancement is available for Aviatrix FireNet deployment with Aviatrix Multi-Cloud Global Transit both in AWS and Azure. This enhancement is also available for AWS-TGW based designs as well.
In this article we will take a look at this enhancement in details with Check Point CloudGuard Firewall.
