Thank you Adam and Arturo for reviewing the package and for your advices. A new packet has been uploaded to mentors [1] with this bug corrected (piuparts tests are OK) and #918715 marked to be closed in the corresponding commit. Is it necessary to open a new RFS bug? Thanks, Alberto [1] https://mentors.debian.net/debian/pool/main/a/arptables/arptables_0.0.4+snapshot20181021-2.dsc
