https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=231144 Bug ID: 231144 Summary: fragmented IPv6 drops Product: Base System Version: 11.2-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: admin@canmos.net Hello! I have a problem with handling fragmented IPv6 packets. Exactly: - My system is FreeBSD 11.2-RELEASE-p2 with GENERIC kernel - I have configured IPv6-only authoritative DNS server And when the oid net.inet6.ip6.forwarding is set to 1, the system stops to receive fragmented IPv6 packets. If i set net.inet6.ip6.forwarding to 0, the behavior is returning to normal. As i know IPv6 packets MUST NO be fragmented by transit gateways itself. But there is no anything said about incoming packets that are ALREADY fragmented. So could you please help me to solve this issue? For comparesion i tried to reproduce the problem under FreeBSD-10.3. There is no any issues with fragmented IPv6, all the packets were handled by system as well, regardless of meaning net.inet6.ip6.forwarding sysctl.
