When viewing output on the System > Packet Capture page, there are two fields that display potentially useful diagnostic information in numeric format. The Module-ID field provides information on the specific area of the firewall (UTM) appliance's firmware that handled a particular packet. The Drop-Code field provides a reason why the appliance dropped a particular packet. This article provides a list of the Module-ID and Drop-Code numbers along with their meanings.
Please Note: The following Drop-Codes were extracted from SonicOS Enhanced 5.8.0.4-7o firmware version, however these codes may change when a new firmware is available. When unsure please contact SonicWall support.
