            Bug ID: 239506
           Summary: ipfw logging doesn't work
           Product: Base System
           Version: 12.0-STABLE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: bugs at FreeBSD.org
          Reporter: yuri at freebsd.org

/etc/rc.conf has:
> firewall_enable="YES"
> firewall_type="open"
> firewall_logif="YES"

I know for a fact that the 'nat' ipfw rule with a "log" keyword works:
> ipfw -q nat 59000 config ip 192.168.5.3 reset log

But tcpdump complains about the promiscuous mode and doesn't log anything:
> # tcpdump -t -n -i ipfw0
> tcpdump: WARNING: ipfw0: That device doesn't support promiscuous mode
> (BIOCPROMISC: Invalid argument)
> tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
> listening on ipfw0, link-type EN10MB (Ethernet), capture size 262144 bytes
