Sometimes when we are using FortiCache with high availability, some problems occur. If the first firewall goes down, sometimes the second firewall does not come up immediately. It only happens sometimes. This issue should be fixed. It is really the only issue I have had with Fortigate. What I would like to see included in future releases is already available in FortiCache, but you currently need a license. It is a wireless controller for the Fortigate firewall. It should be included.
