<p>Hi,</p>
<p>QGIS can run offline. Of course you need Internet to download the
software.</p>
<p>Certain aspects (optional) require an internet connection.
Examples are:</p>
<ul>
<li>Base maps (e.g. OpenStreetmap)</li>
<li>Download of additional plugins from the Repository</li>
<li>Usage of OGC services (WMS/WFS/WMTS)</li>
<li>Some plugins may have additional requirements</li>
</ul>
<p>Regarding ports: the above mentioned services require port 443
and/or 80 (normal web ports). If you want to access databases,
there are additional ports to open (perhaps only on LAN), e.g. for
Postgis the standard port is 5432 - but you can run it on other
ports as well.<br>
</p>
<p>Regarding proxy: if your web browser requires a proxy, QGIS will
have to use the same proxy as well.</p>
<p>Greetings,</p>
<p>Andreas<br>
