NAT-PT Applicability

V6OPS WG

IETF 58, Minneapolis

  • Senthil Sivakumar

  • Suresh Satapati


Goals

Goals

To document the applicability of

  • SIIT (RFC 2765)

  • NAT-PT (RFC 2766)


Siit limitations

SIIT Limitations

  • Usage of IPv4-mapped addresses

  • Translation Semantics – ICMP error messages (embedded headers), parameter problem

  • Multicast will not work

  • Limited support for IPsec ESP Transport mode (doesn’t support ICMP)

  • IPsec ESP tunnel mode, AH doesn’t work


Nat pt limitations

NAT-PT Limitations

  • Difficult to cope up with ALG model to support applications

  • All SIIT limitations + IPsec ESP transport mode doesn’t work

  • DNS-ALG

    • Failure modes for AAAA queries in

      IPv6->IPv4 direction


Applicability

Applicability

  • SIIT

    • header conversion algorithm is useful

    • IPv6 hosts are *really* not IPv6-only

      • RSIP style


Applicability contd

Applicability (contd.)

  • NAT-PT

    • Legacy v4 nodes

    • Special purpose networks – 3gpp

      • 3GPP hosts, running SIP-based IMS applications over IPv6, must be able to communicate with IPv4 SIP hosts

      • For IMS media translation

        • a proxy supplies the mapping as opposed to SIP-ALG
