Re: [v6ops] draft-palet-v6ops-transition-ipv4aas discussion

Hi Med,

In the document I'm editing right now, I've it already support for RFC6887 (464XLAT-2):

   464XLAT requirements:

   464XLAT-1:  The CE Router MUST perform IPv4 Network Address
               Translation (NAT) on IPv4 traffic translated using the
               CLAT, unless a dedicated /64 prefix has been acquired
               using DHCPv6-PD [RFC3633] (IPv6 Prefix Options for
               DHCPv6).

   464XLAT-2:  The CE Router MUST support PCP [RFC6887] (Port Control
               Protocol), for explicit control over NAT64 mappings.

   464XLAT-3:  The CE Router MUST implement [RFC7050] (Discovery of the
               IPv6 Prefix Used for IPv6 Address Synthesis) in order to
               discover the PLAT-side translation IPv4 and IPv6
               prefix(es)/suffix(es).  The CE Router MUST follow
               [RFC7225] (Discovering NAT64 IPv6 Prefixes Using the
               PCP), in order to learn the PLAT-side translation IPv4
               and IPv6 prefix(es)/suffix(es) used by an upstream PCP-
               controlled NAT64 device.

But I now realice that it should be added as well to the DS-Lite section, as it was not present in RFC7084. This is what I've right now:

  DS-Lite requirements:

   DSLITE-1:  The IPv6 CE router MUST support configuration of DS-Lite
              via the DS-Lite DHCPv6 option [RFC6334] (DHCPv6 Option for
              Dual-Stack Lite).  The IPv6 CE router MAY use other
              mechanisms to configure DS-Lite parameters.  Such
              mechanisms are outside the scope of this document.

   DSLITE-2:  The IPv6 CE router MUST NOT perform IPv4 Network Address
              Translation (NAT) on IPv4 traffic encapsulated using DS-
              Lite.

So just to make sure, you mean to add also to both, 464LAT and DS-LITE also a MUST for RFC6970 ?

We have a new section with this text suggested by Richard:

5.  UPnP IGD-PCP IWF Support

   UPnP MAY be enabled on the CE Router for stateless mechanisms that
   forward unsolicited inbound packets through to the CE.  If UPnP is
   enabled, the agent MUST reject any port mapping requests for ports
   outside of the range(s) allocated to the CE Router.

   UPnP SHOULD be disabled for stateful mechanisms that do not forward
   unsolicited inbound packets to the CE Router, unless implemented in
   conjunction with a method to control the external port mapping, such
   as IGD-PCP IWF [RFC6970] (UPnP Internet Gateway Device - Port Control
   Protocol Interworking Function).

Regards,
Jordi

    Hi Jordi, 

    As you are on it, and given the IETF recommendation in RFC6888:

       REQ-9:  A CGN MUST implement a protocol giving subscribers explicit
          control over NAT mappings.  That protocol SHOULD be the Port
          Control Protocol [RFC6887].

    which would apply also to the PLAT, I suggest you add an item in the 464lat section to support RFC6970. 

    Cheers,
    Med
