The issue was first mentioned on isc-bugs. The response I got is: The issue does appear to be in the packaged version. I created a VM with Ubuntu 17.04 and can reproduce your issue using their version.
I then downloaded and built our official version of 4.3.5 and it works correctly. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1743324 Title: dhcrelay package broken. listen on every if independend from the used -id -iu setting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/vlan/+bug/1743324/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
