            Bug ID: 290011
           Summary: ipfw ip6 error when using service name
           Product: Base System
           Version: 14.3-RELEASE
          Hardware: Any
                OS: Any
            Status: New
          Keywords: ipv6
          Severity: Affects Only Me
          Priority: ---
         Component: bin
          Assignee: bugs@FreeBSD.org
          Reporter: brnrd@freebsd.org

When using service names, ipfw fails to translate to port number when using ip6

> ipfw -n add 101 allow ip6 from 3fff:1:2:3::1 dhcp6-client to 3fff:1:2:3::1/64
? ipfw: missing ``to''
> ipfw -n add 00101 allow ip6 from 3fff:1:2:3::1 546 to 3fff:1:2:3::/64
> 00101 allow ip6 from 3fff:1:2:3::1 546 to 3fff:1:2:3::/64

Work-around: use port number in stead of service name.
