Update: Fortinet hat das Problem erkannt und in einem Customer Support Bulletin beschrieben.
In FortiOS v5.0.8 and v5.0.9 and v5.2.0 through v5.2.2, the default value of the firewall service protocol number was changed from a value of 0 to 6.
The most commonly observed impact of this change is that after upgrading to the affected firmware, the “ALL” service matches only TCP traffic.
Executing a factory-reset on the FortiGate device does NOT change the default value to 6.
All FortiGate models.
FortiOS v5.0.10 and v5.2.3 has fixed the issue. Upon upgrading the FortiGate device, the firewall service protocol number is restored to 0.„FortiGate Service ALL nach Firmware Upgrade verändert“ weiterlesen
