https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D241704 Bug ID: 241704 Summary: if_tap not using random MAC upon creation Product: Base System Version: 12.0-STABLE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: vvelox@vvelox.net Updated all my machines to r354217 this week and began running into an issue where once rebooted OpenVPN stopped working. Turns out that all the tap0 interfaces on the machines when they came back up had the MAC 58:9c:fc:10:ff:c4, which prevents prevents ARP from working. To reproduce this... ifconfig tap create ifconfig tap0 ifconfig tap0 destroy ifconfig tap create ifconfig tap0 ifconfig tap0 destroy ifconfig tap create ifconfig tap0 ifconfig tap0 destroy And each time on each machine it will be created with the same MAC. The work around for this is to add a manually set random MAC in via 'ether random' for the line for it in rc.conf. --=20 You are receiving this mail because: You are the assignee for the bug.=
