Hi, Just wanted to mention that according to the changelog, this has been fixed in upstream (since isc-dhcp 4.3.2b1, 4.3.2 has been released some days ago). See ftp://ftp.isc.org/isc/dhcp/4.3.2/dhcp-4.3.2-RELNOTES
[quote] - Modified linux packet handling such that packets received via VLAN are now seen only by the VLAN interface. Prior to this, such packets were seen by both the VLAN interface and its parent (physical) interface, causing the server to respond to both. Note this remains an issue for non-Linux OSs. Thanks to Jiri Popelka at Red Hat for the patch. [ISC-Bugs #37415] [ISC-Bugs #37133] [ISC-Bugs #36668] [ISC-Bugs #36652] [/quote] So all we'd need is a new package with the source from upstream. Cheers, Lorin
