<p>With a SSH tunnel we can send requests from server’s IP and solve a CAPTCHA that
blocks requests from this IP. If your SearXNG instance is hosted at
<code class="docutils literal notranslate"><span class="pre">example.org</span></code> and your login is <code class="docutils literal notranslate"><span class="pre">user</span></code> you can setup a proxy simply by
<a class="reference external" href="https://manpages.debian.org/jump?q=ssh">ssh</a>:</p>
<div class="highlight-bash notranslate"><div class="highlight"><pre><span></span><span class="c1"># SOCKS server: socks://127.0.0.1:8080</span>

<p>The <code class="docutils literal notranslate"><span class="pre">socks://localhost:8080</span></code> from above can be tested by:</p>

<p>In the settings of the WEB browser open the <em>“Network Settings”</em> and setup a
proxy on <code class="docutils literal notranslate"><span class="pre">SOCKS5</span> <span class="pre">127.0.0.1:8080</span></code> (see screenshot below). In the WEB browser
check the IP from the server is used:</p>
<ul class="simple">
<li><p><a class="reference external" href="http://ipecho.net/plain">http://ipecho.net/plain</a></p></li>
</ul>
<p>Now open the search engine that blocks requests from your server’s IP. If you
have <a class="reference external" href="https://github.com/searxng/searxng/issues/2011#issuecomment-1553317619">issues with the qwant engine</a>,
solve the CAPTCHA from <a class="reference external" href="https://www.qwant.com/">qwant.com</a>.</p>
