+Stateful NAT64
+==============
+
+This document describes stateful NAT64 Network Address and Protocol
+Translation
+
+Introduction
+------------
+
+Stateful NAT64 in VPP allows IPv6-only clients to contact IPv4 servers
+using unicast UDP, TCP, or ICMP based on RFC 6146.
+
+Configuration
+-------------
+
+Enable/disable NAT64 feature on the interface
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+   set interface nat64 in|out [del]
+
+in: inside/local/IPv6 network out: outside/external/IPv4 network intfc:
+interface name
+
+Add/delete NAT64 pool address
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+One or more public IPv4 addresses assigned to a NAT64 are shared among
+several IPv6-only clients.
+
+   nat64 add pool address [- ] [tenant-vrf ] [del]
+
+ip4-range-start: First IPv4 address of the range ip4-range-end: Last
+IPv4 address of the range (optional, not used for single address)
+tenant-vrf-id: VRF id of the tenant associated with the pool address
+(optional, if not set pool address is global)
+
+Add/delete static BIB entry
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Stateful NAT64 also supports IPv4-initiated communications to a subset
+of the IPv6 hosts through statically configured bindings.
+
+   nat64 add static bib tcp|udp|icmp [vfr ] [del]
+
+ip6-addr: inside IPv6 address of the host in-port: inside port or ICMPv6
+identifier ip4-addr: outside IPv4 address of the host out-port: outside
+port or ICMPv4 identifier table-id: VRF id of the tenant associated with
+the BIB entry (optional, default use global VRF)
+
+Set NAT64 session timeouts
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Session is deleted when timer expires. If all sessions corresponding to
+a dynamically create BIB entry are deleted, then the BIB entry is also
+deleted. When packets are flowing session timer is refreshed to keep the
+session alive.
+
+   set nat64 timeouts udp icmp tcp-trans tcp-est tcp-incoming-syn \|
+   reset
+
+udp: UDP session timeout value (default 300sec) icmp: ICMP session
+timeout value (default 60sec) tcp-trans: transitory TCP session timeout
+value (default 240sec) tcp-est: established TCP session timeout value
+(default 7440sec) tcp-incoming-syn: incoming SYN TCP session timeout
+value (default 6sec) reset: reset timers to default values
+
+Set NAT64 prefix
+~~~~~~~~~~~~~~~~
+
+Stateful NAT64 support the algorithm for generating IPv6 representations
+of IPv4 addresses defined in RFC 6052. If no prefix is configured,
+Well-Known Prefix (64:ff9b::/96) is used.
+
+   nat64 add prefix / [tenant-vrf ] [del]
+
+ip6-prefix: IPv6 prefix plen: prefix length (valid values: 32, 40, 48,
+56, 64, or 96) tenant-vrf: VRF id of the tenant associated with the
+prefix
+
+Show commands
+~~~~~~~~~~~~~
+
+   show nat64 pool show nat64 interfaces show nat64 bib tcp|udp|icmp
+   show nat64 session table tcp|udp|icmp show nat64 timeouts show nat64
+   prefix
+
+Notes
+-----
+
+Multi thread is not supported yet (CLI/API commands are disabled when
+VPP runs with multiple threads).
