Hi Nathan,
Thanks for providing the solution in the attached cluster guide. I have a few questions -
If a cluster is setup in an active/standby HA configuration, there is a single external VIP. This is used to provision the Zscaler GRE tunnel. Zscaler provides a /29 subnet to be used for the GRE tunnel configuration for 2 tunnels. This does not provide a configuration for 4 tunnels.
As mentioned in the guide, it mentions 2 separate tunnel configurations. Please advise if 2 public IPs were utilized on the firewall cluster. This is not clearly noted.
Also, can you share a screenshot of the SmartConsole Network Management window showing the interface configuration?
If the same GRE configuration is mirrored onto both firewalls, what issues would that present as only a single firewall will be active at any given time.
Thanks
