DHCP-Snooping on FW version 7.4.x

Hello,

We are experiencing a recurring issue with DHCP snooping on several firewalls running FortiOS version 7.4.x, specifically on the FortiGate 40F and 60F models.

When DHCP snooping is enabled, the DHCP server appears to stop assigning IP addresses to clients. This behavior occurs consistently on these models and is resolved immediately when DHCP snooping is disabled, which indicates that the feature is not functioning as expected in this FortiOS version.

We would therefore like to know whether this is a known issue or limitation in FortiOS 7.4.x, and if there are any recommended workarounds, configuration adjustments, or planned fixes in upcoming patch releases.
