DNP3 Preprocessor Options
Ports
Enables inspection of DNP3 traffic on each specified port. You can specify a single port or a comma-separated list of ports.
Log bad CRCs
Validates the checksums contained in DNP3 link layer frames. Frames with invalid checksums are ignored.
You can enable rule 145:1 to generate events and, in an inline deployment, drop offending packets when invalid checksums are detected.
