Found the issue: "Hardware checksum offload" was not deactivated.
Strange thing, the setting was not even present in the configuration. I'm guessing that this setting appear in a recent update and was not set to default, which is activated.
Anyway, my question remains: how would you trace a packet though the OPNSense box to debug this kind of behavior?
