<p>Reticulum supports using many kinds of devices as networking interfaces, and
allows you to mix and match them in any way you choose. The number of distinct
network topologies you can create with Reticulum is more or less endless, but
common to them all is that you will need to define one or more <em>interfaces</em>
for Reticulum to use.</p>
<p>The following sections describe the interfaces currently available in Reticulum,
and gives example configurations for the respective interface types.</p>
<p>For a high-level overview of how networks can be formed over different interface
types, have a look at the <a class="reference internal" href="networks.html#networks-main"><span class="std std-ref">Building Networks</span></a> chapter of this
manual.</p>
<div class="section" id="auto-interface">
<span id="interfaces-auto"></span><h2>Auto Interface<a class="headerlink" href="#auto-interface" title="Permalink to this headline"></a></h2>
<p>The Auto Interface enables communication with other discoverable Reticulum
nodes over autoconfigured IPv6 and UDP. It does not need any functional IP
infrastructure like routers or DHCP servers, but will require at least some
sort of switching medium between peers (a wired switch, a hub, a WiFi access
point or similar), and that link-local IPv6 is enabled in your operating
system, which should be enabled by default in almost all OSes.</p>

<div class="section" id="i2p-interface">
<span id="interfaces-i2p"></span><h2>I2P Interface<a class="headerlink" href="#i2p-interface" title="Permalink to this headline"></a></h2>
<p>The I2P interface lets you connect Reticulum instances over the
<a class="reference external" href="https://i2pd.website">Invisible Internet Protocol</a>. This can be
especially useful in cases where you want to host a globally reachable
Reticulum instance, but do not have access to any public IP addresses,
have a frequently changing IP address, or have firewalls blocking
inbound traffic.</p>
<p>Using the I2P interface, you will get a globally reachable, portable
and persistent I2P address that your Reticulum instance can be reached
at.</p>
<p>To use the I2P interface, you must have an I2P router running
on your system. The easiest way to acheive this is to download and
install the <a class="reference external" href="https://github.com/PurpleI2P/i2pd/releases/latest">latest release</a>
of the <code class="docutils literal notranslate"><span class="pre">ì2pd</span></code> package. For more details about I2P, see the
<a class="reference external" href="https://geti2p.net/en/about/intro">geti2p.net website</a>.`</p>
<p>When an I2P router is running on your system, you can simply add
an I2P interface to reticulum:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="p">[[</span><span class="n">I2P</span><span class="p">]]</span>
<span class="nb">type</span> <span class="o">=</span> <span class="n">I2PInterface</span>
<span class="n">interface_enabled</span> <span class="o">=</span> <span class="n">yes</span>
</pre></div>
</div>
<p>On the first start, Reticulum will generate a new I2P address for the
interface and start listening for inbound traffic on it. This can take
a while the first time, especially if your I2P router was also just
started, and is not yet well-connected to the I2P network. When ready,
you should see I2P base32 address printed to your log file. You can
also inspect the status of the interface using the <code class="docutils literal notranslate"><span class="pre">rnstatus</span></code> utility.</p>
<p>To connect to other Reticulum instances over I2P, just add a comma-separated
list of I2P base32 addresses to the <code class="docutils literal notranslate"><span class="pre">peers</span></code> option of the interface:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="p">[[</span><span class="n">I2P</span><span class="p">]]</span>
<span class="nb">type</span> <span class="o">=</span> <span class="n">I2PInterface</span>
<span class="n">interface_enabled</span> <span class="o">=</span> <span class="n">yes</span>
<span class="n">peers</span> <span class="o">=</span> <span class="mi">5</span><span class="n">urvjicpzi7q3ybztsef4i5ow2aq4soktfj7zedz53s47r54jnqq</span><span class="o">.</span><span class="n">b32</span><span class="o">.</span><span class="n">i2p</span>
</pre></div>
</div>
<p>It can take anywhere from a few seconds to a few minutes to establish
I2P connections to the desired peers, so Reticulum handles the process
in the background, and will output relevant events to the log.</p>
<p><strong>Please Note!</strong> While the I2P interface is the simplest way to use
Reticulum over I2P, it is also possible to tunnel the TCP server and
client interfaces over I2P manually. This can be useful in situations
where more control is needed, but requires manual tunnel setup through
the I2P daemon configuration.</p>
<p>It is important to note that the two methods are <em>interchangably compatible</em>.
You can use the I2PInterface to connect to a TCPServerInterface that
was manually tunneled over I2P, for example. This offers a high degree
of flexibility in network setup, while retaining ease of use in simpler
use-cases.</p>

<div class="section" id="tcp-server-interface">
<span id="interfaces-tcps"></span><h2>TCP Server Interface<a class="headerlink" href="#tcp-server-interface" title="Permalink to this headline"></a></h2>
<p>The TCP Server interface is suitable for allowing other peers to connect over

<p>To connect to a TCP server interface, you would naturally use the TCP client
interface. Many TCP Client interfaces from different peers can connect to the
same TCP Server interface at the same time.</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="c1"># Here&#39;s an example of a TCP Client interface. The</span>

<p>It is also possible to use this interface type to connect via other programs

software-based soundmodems. To do this, use the <code class="docutils literal notranslate"><span class="pre">kiss_framing</span></code> option:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="c1"># Here&#39;s an example of a TCP Client interface that connects</span>

</div>
<p><strong>Caution!</strong> Only use the KISS framing option when connecting to external devices
and programs like soundmodems and similar over TCP. When using the
<code class="docutils literal notranslate"><span class="pre">TCPClientInterface</span></code> in conjunction with the <code class="docutils literal notranslate"><span class="pre">TCPServerInterface</span></code> you should
never enable <code class="docutils literal notranslate"><span class="pre">kiss_framing</span></code>, since this will disable internal reliability and
recovery mechanisms that greatly improves performance over unreliable and

<p>A UDP interface can be useful for communicating over IP networks, both
private and the internet. It can also allow broadcast communication
over IP networks, so it can provide an easy way to enable connectivity

<p>If youre using Reticulum on amateur radio spectrum, you might want to
use the AX.25 KISS interface. This way, Reticulum will automatically
encapsulate its traffic in AX.25 and also identify your stations
transmissions with your callsign and SSID.</p>
<p>Only do this if you really need to! Reticulum doesnt need the AX.25
layer for anything, and it incurs extra overhead on every packet to
encapsulate in AX.25.</p>
<p>A more efficient way is to use the plain KISS interface with the
beaconing functionality described above.</p>

<span id="interfaces-options"></span><h2>Common Interface Options<a class="headerlink" href="#common-interface-options" title="Permalink to this headline"></a></h2>
<p>A number of general options can be used to control various
aspects of interface behaviour.</p>
<p>The <code class="docutils literal notranslate"><span class="pre">interface_enabled</span></code> option tells Reticulum whether or not
to bring up the interface. Defaults to <code class="docutils literal notranslate"><span class="pre">False</span></code>. For any
interface to be brought up, the <code class="docutils literal notranslate"><span class="pre">interface_enabled</span></code> option
must be set to <code class="docutils literal notranslate"><span class="pre">True</span></code> or <code class="docutils literal notranslate"><span class="pre">Yes</span></code>.</p>
<p>The <code class="docutils literal notranslate"><span class="pre">outgoing</span></code> option sets whether an interface is allowed
to transmit. Defaults to <code class="docutils literal notranslate"><span class="pre">True</span></code>. If set to <code class="docutils literal notranslate"><span class="pre">False</span></code> the
interface will only receive data, and never transmit.</p>
<p>The <code class="docutils literal notranslate"><span class="pre">interface_mode</span></code> option allows selecting the high-level
behaviour of the interface from a number of options.</p>
<blockquote>
<div><ul class="simple">
<li><p>The default value is <code class="docutils literal notranslate"><span class="pre">full</span></code>. In this mode, all discovery,
meshing and transpor functionality is available.</p></li>
<li><p>In the <code class="docutils literal notranslate"><span class="pre">access_point</span></code> (or shorthand <code class="docutils literal notranslate"><span class="pre">ap</span></code>) mode, the
interface will operate as a network access point. In this
mode, announces will not be automatically broadcasted on
the interface, and paths to destinations on the interface
will have a much shorter expiry time. This mode is useful
for creating interfaces that are mostly quiet, unless when
someone is actually using them. An example of this could
be a radio interface serving a wide area, where users are
expected to connect momentarily, use the network, and then
disappear again.</p></li>
