Why each option

Possible reasons for FortiGate push updates not being received include improper external interface configuration (like DHCP issues), an unregistered unit, or unconfigured NAT for FortiGuard communication.

AThe external facing interface of the FortiGate unit is configured to use DHCP.Correct

While DHCP itself is not a barrier, if the DHCP configuration on the external-facing interface fails to provide proper internet connectivity, such as incorrect DNS servers or a missing default gateway, the FortiGate unit would be unable to reach the FortiGuard Distribution Network to receive updates.

BThe FortiGate unit has not been registered.Correct

A FortiGate unit must be properly registered with FortiGuard services to receive any updates, whether they are pulled or pushed, as registration links the device to its support contract and entitlements.

CThere is a NAT device between the FortiGate unit and the FortiGuard Distribution Network and noCorrect

If a NAT device sits between the FortiGate and FortiGuard, and port forwarding or a proper outbound NAT rule is not configured to allow the FortiGate to communicate with FortiGuard servers, then updates cannot be received.

DThe FortiGate unit is in Transparent mode which does not support push updates.

FortiGate units operating in Transparent mode can still receive and apply FortiGuard updates, as Transparent mode relates to Layer 2 forwarding of traffic, not its ability to communicate with external services like FortiGuard.
