            Bug ID: 216867
           Summary: IPFW workstation rules block DNSSEC resulting in DNS
                    failure on freebsd.org domains
           Product: Base System
           Version: 11.0-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: conf
          Assignee: freebsd-bugs@FreeBSD.org
          Reporter: freebsd-bugs@rsle.net
                CC: freebsd-amd64@FreeBSD.org

The default IPFW "workstation" rules seem to block fragmented packets cause=
d by
DNSSEC, in turn causing DNS to fail for some domains (including freebsd.org
subdomains) when DNS resolution is performed locally (using BIND or Unbound=
).

Fix:
The addition of the IPFW rule "ipfw add reass udp from any to any in" to
/etc/rc.firewall, under type workstation, fixes the issue.
