  ip6fw does not recognize ESP packets correctly when the packets are specified
  as protocol 50 (or "ESP") by the ip6fw command.  For example, even if the
  following line is installed:

  add pass esp from any to any

  The kernel does not apply this rule to IPv6 ESP packets.  Instead, we need
  to specify like this:

  add pass all from any to any ipv6options esp
