The “iprope_in_check() check failed, drop” message indicates that the incoming packet failed an internal check related to routing or address translation. Two common causes are:
- Policy Route Misconfiguration (A): If a policy route is set up incorrectly (e.g., with an incorrect gateway or matching criteria), the packet might not receive the proper routing treatment and will be dropped.
- VIP or IP Pool Misconfiguration (D): When the VIP (Virtual IP) or IP pool settings are misconfigured, the FortiGate may not correctly translate or match the packet to a valid address, resulting in the drop.
