+
+:abbr:`NAT (Network Address Translation)` is a common method of
+remapping one IP address space into another by modifying network address
+information in the IP header of packets while they are in transit across
+a traffic routing device. The technique was originally used as a
+shortcut to avoid the need to readdress every host when a network was
+moved. It has become a popular and essential tool in conserving global
+address space in the face of IPv4 address exhaustion. One
+Internet-routable IP address of a NAT gateway can be used for an entire
+private network.
+
+IP masquerading is a technique that hides an entire IP address space,
+usually consisting of private IP addresses, behind a single IP address
+in another, usually public address space. The hidden addresses are
+changed into a single (public) IP address as the source address of the
+outgoing IP packets so they appear as originating not from the hidden
+host but from the routing device itself. Because of the popularity of
+this technique to conserve IPv4 address space, the term NAT has become
+virtually synonymous with IP masquerading.
+
+As network address translation modifies the IP address information in
+packets, NAT implementations may vary in their specific behavior in
+various addressing cases and their effect on network traffic. The
+specifics of NAT behavior are not commonly documented by vendors of
+equipment containing NAT implementations.
+
+The computers on an internal network can use any of the addresses set
+aside by the :abbr:`IANA (Internet Assigned Numbers Authority)` for
+private addressing (see :rfc:`1918`). These reserved IP addresses are
+not in use on the Internet, so an external machine will not directly
+route to them. The following addresses are reserved for private use:
+
+* 10.0.0.0 to 10.255.255.255 (CIDR: 10.0.0.0/8)
+* 172.16.0.0 to 172.31.255.255 (CIDR: 172.16.0.0/12)
+* 192.168.0.0 to 192.168.255.255 (CIDR: 192.168.0.0/16)
+
+
+If an ISP deploys a :abbr:`CGN (Carrier-grade NAT)`, and uses
+:rfc:`1918` address space to number customer gateways, the risk of
+address collision, and therefore routing failures, arises when the
+customer network already uses an :rfc:`1918` address space.
+
+This prompted some ISPs to develop a policy within the :abbr:`ARIN
+(American Registry for Internet Numbers)` to allocate new private
+address space for CGNs, but ARIN deferred to the IETF before
+implementing the policy indicating that the matter was not a typical
+allocation issue but a reservation of addresses for technical purposes
+(per :rfc:`2860`).
+
+IETF published :rfc:`6598`, detailing a shared address space for use in
+ISP CGN deployments that can handle the same network prefixes occurring
+both on inbound and outbound interfaces. ARIN returned address space to
+the :abbr:`IANA (Internet Assigned Numbers Authority)` for this
+allocation.
+
+The allocated address block is 100.64.0.0/10.
+
+Devices evaluating whether an IPv4 address is public must be updated to
+recognize the new address space. Allocating more private IPv4 address
+space for NAT devices might prolong the transition to IPv6.
+
+Overview
+========
+
+Different NAT Types
+-------------------
+
+.. _source-nat:
+
+SNAT
+^^^^
+
+:abbr:`SNAT (Source Network Address Translation)` is the most common
+form of :abbr:`NAT (Network Address Translation)` and is typically
+referred to simply as NAT. To be more correct, what most people refer
+to as :abbr:`NAT (Network Address Translation)` is actually the process
+of :abbr:`PAT (Port Address Translation)`, or NAT overload. SNAT is
+typically used by internal users/private hosts to access the Internet
+- the source address is translated and thus kept private.
+
+.. _destination-nat:
+
+DNAT
+^^^^
+
+:abbr:`DNAT (Destination Network Address Translation)` changes the
+destination address of packets passing through the router, while
+:ref:`source-nat` changes the source address of packets. DNAT is
+typically used when an external (public) host needs to initiate a
+session with an internal (private) host. A customer needs to access a
+private service behind the routers public IP. A connection is
+established with the routers public IP address on a well known port and
+thus all traffic for this port is rewritten to address the internal
+(private) host.
+
+.. _bidirectional-nat:
+
+Bidirectional NAT
+^^^^^^^^^^^^^^^^^
+
+This is a common scenario where both :ref:`source-nat` and
+:ref:`destination-nat` are configured at the same time. It's commonly
+used then internal (private) hosts need to establish a connection with
+external resources and external systems need to access internal
+(private) resources.
+
+NAT, Routing, Firewall Interaction
+----------------------------------
+
+There is a very nice picture/explanation in the Vyatta documentation
+which should be rewritten here.
+
+NAT Ruleset
+-----------
+
+:abbr:`NAT (Network Address Translation)` is configured entirely on a
+series of so called `rules`. Rules are numbered and evaluated by the
+underlying OS in numerical order! The rule numbers can be changes by
+utilizing the :cfgcmd:`rename` and :cfgcmd:`copy` commands.
+
+.. note:: Changes to the NAT system only affect newly established
+   connections. Already established connections are not affected.
+
+.. hint:: When designing your NAT ruleset leave some space between
+   consecutive rules for later extension. Your ruleset could start with
+   numbers 10, 20, 30. You thus can later extend the ruleset and place
+   new rules between existing ones.
+
+Rules will be created for both :ref:`source-nat` and
+:ref:`destination-nat`.
+
+For :ref:`bidirectional-nat` a rule for both :ref:`source-nat` and
+:ref:`destination-nat` needs to be created.
+
+.. _traffic-filters:
+
+Traffic Filters
+---------------
+
+Traffic Filters are used to control which packets will have the defined
+NAT rules applied. Five different filters can be applied within a NAT
+rule.
+
+* **outbound-interface** - applicable only to :ref:`source-nat`. It
+  configures the interface which is used for the outside traffic that
+  this translation rule applies to.
+
+  Example:
+
+  .. code-block:: none
+
+    set nat source rule 20 outbound-interface eth0
+
+* **inbound-interface** - applicable only to :ref:`destination-nat`. It
+  configures the interface which is used for the inside traffic the
+  translation rule applies to.
+
+  Example:
+
+  .. code-block:: none
+
+    set nat destination rule 20 inbound-interface eth1
+
+* **protocol** - specify which types of protocols this translation rule
+  applies to. Only packets matching the specified protocol are NATed. By default this
+  applies to `all` protocols.
+
+  Example:
+
+  * Set SNAT rule 20 to only NAT TCP and UDP packets
+  * Set DNAT rule 20 to only NAT UDP packets
+
+  .. code-block:: none
+
+    set nat source rule 20 protocol tcp_udp
+    set nat destination rule 20 protocol udp
+
+* **source** - specifies which packets the NAT translation rule applies
+  to based on the packets source IP address and/or source port. Only
+  matching packets are considered for NAT.
+
+  Example:
+
+  * Set SNAT rule 20 to only NAT packets arriving from the 192.0.2.0/24
+    network
+  * Set SNAT rule 30 to only NAT packets arriving from the 192.0.3.0/24
+    network with a source port of 80 and 443
+
+  .. code-block:: none
+
+    set nat source rule 20 source address 192.0.2.0/24
+    set nat source rule 30 source address 192.0.3.0/24
+    set nat source rule 30 source port 80,443
+
+
+* **destination** - specify which packets the translation will be
+  applied to, only based on the destination address and/or port number
+  configured.
+
+  .. note:: If no destination is specified the rule will match on any
+     destination address and port.
+
+  Example:
+
+  * Configure SNAT rule (40) to only NAT packets with a destination
+    address of 192.0.2.1.
+
+  .. code-block:: none
+
+    set nat source rule 40 destination address 192.0.2.1
+
+
+Address Conversion
+------------------
+
+Every NAT rule has a translation command defined. The address defined
+for the translation is the address used when the address information in
+a packet is replaced.
+
+Source Address
+^^^^^^^^^^^^^^
+
+For :ref:`source-nat` rules the packets source address will be replaced
+with the address specified in the translation command. A port
+translation can also be specified and is part of the translation
+address.
+
+.. note:: The translation address must be set to one of the available
+   addresses on the configured `outbound-interface` or it must be set to
+   `masquerade` which will use the primary IP address of the
+   `outbound-interface` as its translation address.
+
+.. note:: When using NAT for a large number of host systems it
+   recommended that a minimum of 1 IP address is used to NAT every 256
+   private host systems. This is due to the limit of 65,000 port numbers
+   available for unique translations and a reserving an average of
+   200-300 sessions per host system.
+
+Example:
+
+* Define a discrete source IP address of 100.64.0.1 for SNAT rule 20
+* Use address `masquerade` (the interfaces primary address) on rule 30
+* For a large amount of private machines behind the NAT your address
+  pool might to be bigger. Use any address in the range 100.64.0.10 -
+  100.64.0.20 on SNAT rule 40 when doing the translation
+
+
+.. code-block:: none
+
+  set nat source rule 20 translation address 100.64.0.1
+  set nat source rule 30 translation address 'masquerade'
+  set nat source rule 40 translation address 100.64.0.10-100.64.0.20
+
+
+Destination Address
+^^^^^^^^^^^^^^^^^^^
+
+For :ref:`destination-nat` rules the packets destination address will be
+replaced by the specified address in the `translation address` command.
+
+Example:
+
+* DNAT rule 10 replaces the destination address of an inbound packet
+  with 192.0.2.10
+
+.. code-block:: none
+
+  set nat destination rule 10 translation address 192.0.2.10
+
+
+Configuration Examples
+======================
+
+To setup SNAT, we need to know:
+
+* The internal IP addresses we want to translate
+* The outgoing interface to perform the translation on
+* The external IP address to translate to
+
+In the example used for the Quick Start configuration above, we
+demonstrate the following configuration:
+
+.. code-block:: none
+
+  set nat source rule 100 outbound-interface 'eth0'
+  set nat source rule 100 source address '192.168.0.0/24'
+  set nat source rule 100 translation address 'masquerade'
+
+Which generates the following configuration:
+
+.. code-block:: none
+
+  rule 100 {
+      outbound-interface eth0
+      source {
+          address 192.168.0.0/24
+      }
+      translation {
+          address masquerade
+      }
+  }
+
+In this example, we use **masquerade** as the translation address
+instead of an IP address. The **masquerade** target is effectively an
+alias to say "use whatever IP address is on the outgoing interface",
+rather than a statically configured IP address. This is useful if you
+use DHCP for your outgoing interface and do not know what the external
+address will be.
+
+When using NAT for a large number of host systems it recommended that a
+minimum of 1 IP address is used to NAT every 256 host systems. This is
+due to the limit of 65,000 port numbers available for unique
+translations and a reserving an average of 200-300 sessions per host
+system.
+
+Example: For an ~8,000 host network a source NAT pool of 32 IP addresses
+is recommended.
+
+A pool of addresses can be defined by using a hyphen between two IP
+addresses:
+
+.. code-block:: none
+
+  set nat source rule 100 translation address '203.0.113.32-203.0.113.63'
+
+.. _avoidng_leaky_nat:
+
+Avoiding "leaky" NAT
+--------------------
+
+Linux netfilter will not NAT traffic marked as INVALID. This often
+confuses people into thinking that Linux (or specifically VyOS) has a
+broken NAT implementation because non-NATed traffic is seen leaving an
+external interface. This is actually working as intended, and a packet
+capture of the "leaky" traffic should reveal that the traffic is either
+an additional TCP "RST", "FIN,ACK", or "RST,ACK" sent by client systems
+after Linux netfilter considers the connection closed. The most common
+is the additional TCP RST some host implementations send after
+terminating a connection (which is implementation-specific).
+
+In other words, connection tracking has already observed the connection
+be closed and has transition the flow to INVALID to prevent attacks from
+attempting to reuse the connection.
+
+You can avoid the "leaky" behavior by using a firewall policy that drops
+"invalid" state packets.
+
+Having control over the matching of INVALID state traffic, e.g. the
+ability to selectively log, is an important troubleshooting tool for
+observing broken protocol behavior. For this reason, VyOS does not
+globally drop invalid state traffic, instead allowing the operator to
+make the determination on how the traffic is handled.
+
+.. _hairpin_nat_reflection:
+
+Hairpin NAT/NAT Reflection
+--------------------------
+
+A typical problem with using NAT and hosting public servers is the
+ability for internal systems to reach an internal server using it's
+external IP address. The solution to this is usually the use of
+split-DNS to correctly point host systems to the internal address when
+requests are made internally. Because many smaller networks lack DNS
+infrastructure, a work-around is commonly deployed to facilitate the
+traffic by NATing the request from internal hosts to the source address
+of the internal interface on the firewall.
+
+This technique is commonly referred to as NAT Reflection or Hairpin NAT.
+
+Example:
+
+* Redirect Microsoft RDP traffic from the outside (WAN, external) world
+  via :ref:`destination-nat` in rule 100 to the internal, private host
+  192.0.2.40.
+
+* Redirect Microsoft RDP traffic from the internal (LAN, private)
+  network via :ref:`destination-nat` in rule 110 to the internal,
+  private host 192.0.2.40. We also need a :ref:`source-nat` rule 110 for
+  the reverse path of the traffic. The internal network 192.0.2.0/24 is
+  reachable via interface `eth0.10`.
+
+.. code-block:: none
+
+  set nat destination rule 100 description 'Regular destination NAT from external'
+  set nat destination rule 100 destination port '3389'
+  set nat destination rule 100 inbound-interface 'pppoe0'
+  set nat destination rule 100 protocol 'tcp'
+  set nat destination rule 100 translation address '192.0.2.40'
+
+  set nat destination rule 110 description 'NAT Reflection: INSIDE'
+  set nat destination rule 110 destination port '3389'
+  set nat destination rule 110 inbound-interface 'eth0.10'
+  set nat destination rule 110 protocol 'tcp'
+  set nat destination rule 110 translation address '192.0.2.40'
+
+  set nat source rule 110 description 'NAT Reflection: INSIDE'
+  set nat source rule 110 destination address '192.0.2.0/24'
+  set nat source rule 110 outbound-interface 'eth0.10'
+  set nat source rule 110 protocol 'tcp'
+  set nat source rule 110 source address '192.0.2.0/24'
+  set nat source rule 110 translation address 'masquerade'
+
+Which results in a configuration of:
+
+.. code-block:: none
+
+  vyos@vyos# show nat
+   destination {
+       rule 100 {
+           description "Regular destination NAT from external"
+           destination {
+               port 3389
+           }
+           inbound-interface pppoe0
+           protocol tcp
+           translation {
+               address 192.0.2.40
+           }
+       }
+       rule 110 {
+           description "NAT Reflection: INSIDE"
+           destination {
+               port 3389
+           }
+           inbound-interface eth0.10
+           protocol tcp
+           translation {
+               address 192.0.2.40
+           }
+       }
+   }
+   source {
+       rule 110 {
+           description "NAT Reflection: INSIDE"
+           destination {
+               address 192.0.2.0/24
+           }
+           outbound-interface eth0.10
+           protocol tcp
+           source {
+               address 192.0.2.0/24
+           }
+           translation {
+               address masquerade
+           }
+       }
+   }
+
+
+Destination NAT
+---------------
+
+DNAT is typically referred to as a **Port Forward**. When using VyOS as
+a NAT router and firewall, a common configuration task is to redirect
+incoming traffic to a system behind the firewall.
+
+In this example, we will be using the example Quick Start configuration
+above as a starting point.
+
+To setup a destination NAT rule we need to gather:
+
+* The interface traffic will be coming in on;
+* The protocol and port we wish to forward;
+* The IP address of the internal system we wish to forward traffic to.
+
+In our example, we will be forwarding web server traffic to an internal
+web server on 192.168.0.100. HTTP traffic makes use of the TCP protocol
+on port 80. For other common port numbers, see:
+https://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers
+
+Our configuration commands would be:
+
+.. code-block:: none
+
+  set nat destination rule 10 description 'Port Forward: HTTP to 192.168.0.100'
+  set nat destination rule 10 destination port '80'
+  set nat destination rule 10 inbound-interface 'eth0'
+  set nat destination rule 10 protocol 'tcp'
+  set nat destination rule 10 translation address '192.168.0.100'
+
+Which would generate the following NAT destination configuration:
+
+.. code-block:: none
+
+  nat {
+      destination {
+          rule 10 {
+              description "Port Forward: HTTP to 192.168.0.100"
+              destination {
+                  port 80
+              }
+              inbound-interface eth0
+              protocol tcp
+              translation {
+                  address 192.168.0.100
+              }
+          }
+      }
+  }
+
+.. note:: If forwarding traffic to a different port than it is arriving
+   on, you may also configure the translation port using
+   `set nat destination rule [n] translation port`.
+
+This establishes our Port Forward rule, but if we created a firewall
+policy it will likely block the traffic.
+
+It is important to note that when creating firewall rules that the DNAT
+translation occurs **before** traffic traverses the firewall. In other
+words, the destination address has already been translated to
+192.168.0.100.
+
+So in our firewall policy, we want to allow traffic coming in on the
+outside interface, destined for TCP port 80 and the IP address of
+192.168.0.100.
+
+.. code-block:: none
+
+  set firewall name OUTSIDE-IN rule 20 action 'accept'
+  set firewall name OUTSIDE-IN rule 20 destination address '192.168.0.100'
+  set firewall name OUTSIDE-IN rule 20 destination port '80'
+  set firewall name OUTSIDE-IN rule 20 protocol 'tcp'
+  set firewall name OUTSIDE-IN rule 20 state new 'enable'
+
+This would generate the following configuration:
+
+.. code-block:: none
+
+  rule 20 {
+      action accept
+      destination {
+          address 192.168.0.100
+          port 80
+      }
+      protocol tcp
+      state {
+          new enable
+      }
+  }
+
+.. note::
+
+  If you have configured the `INSIDE-OUT` policy, you will need to add
+  additional rules to permit inbound NAT traffic.
+
+1-to-1 NAT
+----------
+
+Another term often used for DNAT is **1-to-1 NAT**. For a 1-to-1 NAT
+configuration, both DNAT and SNAT are used to NAT all traffic from an
+external IP address to an internal IP address and vice-versa.
+
+Typically, a 1-to-1 NAT rule omits the destination port (all ports) and
+replaces the protocol with either **all** or **ip**.
+
+Then a corresponding SNAT rule is created to NAT outgoing traffic for
+the internal IP to a reserved external IP. This dedicates an external IP
+address to an internal IP address and is useful for protocols which
+don't have the notion of ports, such as GRE.
+
+Here's an extract of a simple 1-to-1 NAT configuration with one internal
+and one external interface:
+
+.. code-block:: none
+
+  set interfaces ethernet eth0 address '192.168.1.1/24'
+  set interfaces ethernet eth0 description 'Inside interface'
+  set interfaces ethernet eth1 address '192.0.2.30/24'
+  set interfaces ethernet eth1 description 'Outside interface'
+  set nat destination rule 2000 description '1-to-1 NAT example'
+  set nat destination rule 2000 destination address '192.0.2.30'
+  set nat destination rule 2000 inbound-interface 'eth1'
+  set nat destination rule 2000 translation address '192.168.1.10'
+  set nat source rule 2000 description '1-to-1 NAT example'
+  set nat source rule 2000 outbound-interface 'eth1'
+  set nat source rule 2000 source address '192.168.1.10'
+  set nat source rule 2000 translation address '192.0.2.30'
+
+Firewall rules are written as normal, using the internal IP address as
+the source of outbound rules and the destination of inbound rules.
+
+NAT before VPN
+--------------
+
+Some application service providers (ASPs) operate a VPN gateway to
+provide access to their internal resources, and require that a
+connecting organisation translate all traffic to the service provider
+network to a source address provided by the ASP.
+
+Example Network
+^^^^^^^^^^^^^^^
+
+Here's one example of a network environment for an ASP.
+The ASP requests that all connections from this company should come from
+172.29.41.89 - an address that is assigned by the ASP and not in use at
+the customer site.
+
+.. figure:: _static/images/nat_before_vpn_topology.png
+   :scale: 100 %
+   :alt: NAT before VPN Topology
+
+   NAT before VPN Topology
+
+
+Configuration
+^^^^^^^^^^^^^
+
+The required configuration can be broken down into 4 major pieces:
+
+* A dummy interface for the provider-assigned IP;
+* NAT (specifically, Source NAT);
+* IPSec IKE and ESP Groups;
+* IPSec VPN tunnels.
+
+
+Dummy interface
+"""""""""""""""
+
+The dummy interface allows us to have an equivalent of the Cisco IOS
+Loopback interface - a router-internal interface we can use for IP
+addresses the router must know about, but which are not actually
+assigned to a real network.
+
+We only need a single step for this interface:
+
+.. code-block:: none
+
+  set interfaces dummy dum0 address '172.29.41.89/32'

+The ASP has documented their IPSec requirements:
+
+* IKE Phase:
+
+  * aes256 Encryption
+  * sha256 Hashes
+
+* ESP Phase:
+
+  * aes256 Encryption
+  * sha256 Hashes
+  * DH Group 14
+
+
+Additionally, we want to use VPNs only on our eth1 interface (the

+IPSec VPN Tunnels
+"""""""""""""""""
+
+We'll use the IKE and ESP groups created above for this VPN. Because we
+need access to 2 different subnets on the far side, we will need two
+different tunnels. If you changed the names of the ESP group and IKE
+group in the previous step, make sure you use the correct names here
+too.

+Testing and Validation
+""""""""""""""""""""""
+
+If you've completed all the above steps you no doubt want to see if it's
+all working.
+
+Start by checking for IPSec SAs (Security Associations) with:
+
+.. code-block:: none
+
+  $ show vpn ipsec sa
+
+  Peer ID / IP                            Local ID / IP
+  ------------                            -------------
+  198.51.100.243                          203.0.113.46
+
+      Tunnel  State  Bytes Out/In   Encrypt  Hash    NAT-T  A-Time  L-Time  Proto
+      ------  -----  -------------  -------  ----    -----  ------  ------  -----
+      0       up     0.0/0.0        aes256   sha256  no     1647    3600    all
+      1       up     0.0/0.0        aes256   sha256  no     865     3600    all
+
+That looks good - we defined 2 tunnels and they're both up and running.
