http://bugzilla.opensuse.org/show_bug.cgi?id=1153813 Bug ID: 1153813 Summary: After Upgrade from 15.0 to 15.1 IPv6 forwarding is broken Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.1 Hardware: x86-64 OS: SUSE Other Status: NEW Severity: Critical Priority: P5 - None Component: Network Assignee: bnc-team-screening@forge.provo.novell.com Reporter: Mathias.Homann@opensuse.org QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- I upgraded my main firewall/router to Leap 15.1, and since then several things about IPv6 do not work anymore: - the external interface does not accept RA anymore even though net.ipv6.conf.all.accept_ra = 1 and net.ipv6.conf.eth1.accept_ra = 2 are set properly, like they have been set in 15.0 - the firewall does not forward IPv6 traffic anymore Fun part: The part about not accepting RA information anymore only started a few reboots after the upgrade; before that I could still talk IPv6 from the firewall itself, but obviously not from any machine behind it. -- You are receiving this mail because: You are on the CC list for the bug.
