 <div class="body conbody"><p class="shortdesc">Network Address Translation (NAT, also known as network masquerading or IP masquerading)
  rewrites the source and/or destination addresses/ports of IP packets as they pass through a router
  or firewall. It is most commonly used to connect multiple computers to the Internet (or any other
  IP network) by using one IP address. This allows home users and small businesses to cheaply and
  efficiently connect their network to the Internet. </p>
  <p class="p">The basic purpose of NAT is to multiplex traffic from the internal network and present it to
   the Internet as if it was coming from a single computer having only one IP address. The Mediatrix
   unit’s NAT service allows the dynamic creation and configuration of network address translation
   rules. Depending on some criteria, the packet matching the rule may see its source or destination
   address modified. </p>
  <div class="p">There are two types of NAT rules:<ul class="ul" id="concept_qjy_ryp_vhb__ul_cmd_bzp_vhb">
    <li class="li"> Source rules: They are applied on the source address of outgoing packets. </li>
    <li class="li">Destination rules: They are applied on the destination address of incoming packets. </li>
   </ul> A rule's priority is determined by its index in the Source NAT or Destination NAT tables
   (Network/NAT). If the NAT service is stopped, this tab is greyed out and the parameters are not
   displayed. </div>
  <div class="p">The maximum number of rules allowed in the configuration is 10 of each Source NAT and
   Destination NAT. <div class="note note note_note"><span class="note__title">Note:</span> Adding source or destination NAT rules has an impact on the Mediatrix
    unit’s overall performance as the NAT requires additional processing. The more rules are
    enabled, the more overall performance is affected. Furthermore, Media5 recommends to use a 30 ms
    packetization time when the NAT is enabled (instead of a 20 ms ptime, for instance) in order to
    simultaneously use all the channels available on the unit.</div><div class="note note note_note"><span class="note__title">Note:</span> The Mediatrix unit NAT
    service does not support IPv6</div></div>

 <div class="body conbody"><p class="shortdesc">Mediatrix devices are supplied with an exhaustive set of documentation. </p>
  <p class="p">Mediatrix user documentation is available on the <a class="xref" href="http://documentation.media5corp.com" target="_blank">Media5 Documentation
    Portal</a>.</p>
  <div class="p">Several types of documents were created to clearly present the information you are looking for.
   Our documentation includes:<ul class="ul" id="concept_v4k_q3h_1r__ul_bqy_cjh_1r">
    <li class="li"><strong class="ph b">Release notes</strong>: Generated at each GA release, this document includes the known and
     solved issues of the software. It also outlines the changes and the new features the release
     includes.</li>
    <li class="li"><strong class="ph b">Configuration notes</strong>: These documents are created to facilitate the configuration of a
     specific use case. They address a configuration aspect we consider that most users will need to
     perform. However, in some cases, a configuration note is created after receiving a question
     from a customer. They provide standard step-by-step procedures detailing the values of the
     parameters to use. They provide a means of validation and present some conceptual information.
     The configuration notes are specifically created to guide the user through an aspect of the
     configuration. </li>
    <li class="li"><strong class="ph b">Technical bulletins</strong>: These documents are created to facilitate the configuration of a
     specific technical action, such as performing a firmware upgrade.</li>
    <li class="li"><strong class="ph b">Hardware installation guide</strong>: They provide the detailed procedure on how to safely and
     adequately install the unit. It provides information on card installation, cable connections,
     and how to access for the first time the Management interface.</li>
    <li class="li"><strong class="ph b">User guide</strong>: The user guide explains how to customise to your needs the configuration
     of the unit. Although this document is task oriented, it provides conceptual information to
     help the user understand the purpose and impact of each task. The User Guide will provide
     information such as where and how TR-069 can be configured in the Management Interface, how to
     set firewalls, or how to use the CLI to configure parameters that are not available in the
     Management Interface.</li>
    <li class="li"><strong class="ph b">Reference guide</strong>: This exhaustive document has been created for advanced users. It
     includes a description of all the parameters used by all the services of the Mediatrix units.
     You will find, for example, scripts to configure a specific parameter, notification messages
     sent by a service, or an action description used to create Rulesets. This document includes
     reference information such as a dictionary, and it does not include any step-by-step
     procedures. </li>
