<dt><strong>How can I connect my Android or IOS device to my Netmaker VPN?</strong></dt><dd><p>Currently meshing one of these devices is not supported, however it will be soon.
|
||
For now you can connect to your VPN by making one of the nodes an Ingress Gateway, then
|
||
create an Ext Client for each device. Finally, use the official WG app or another
|
||
WG configuration app to connect via QR or downloading the device’s WireGuard configuration.</p>
|
||
</dd>
|
||
<dt><strong>I’ve made changes to my nodes but the nodes themselves haven’t updated yet, why?</strong></dt><dd><p>Please allow your nodes to complete a check in or two, in order to reconfigure themselves.
|
||
In some cases, it could take up to a minute or so.</p>
|
||
</dd>
|
||
<dt><strong>Do I have to use access keys to join a network?</strong></dt><dd><p>Although keys are the preferred way to join a network, Netmaker does allow for manual node sign-ups.
|
||
Simply turn on “allow manual signups” on your network and nodes will not connect until you manually aprove each one.</p>
|
||
</dd>
|
||
<dt><strong>Is there a community or forum to ask questions about Netmaker?</strong></dt><dd><p>Yes, we have an active <a class="reference external" href="https://discord.gg/Pt4T9y9XK8">discord</a> community and issues on our <a class="reference external" href="https://github.com/gravitl/netmaker/issues">github</a> are answered frequently!

<dt><strong>I upgraded from 0.7 to 0.8 and now I dont have any data in my server!</strong></dt><dd><p>In 0.8, sqlite becomes the default database. If you were running with rqlite, you must set the DATABASE environment variable to rqlite in order to continue using rqlite.</p>
|

</dd>
|
||
<dt><strong>Can I secure/encrypt all the traffic to my server and UI?</strong></dt><dd><p>This can fairly simple to achieve assuming you have access to a domain and are familiar with Nginx.
|
||
Please refer to the quick-start guide to see!</p>
|
||
</dd>
|
||
<dt><strong>Can I connect multiple nodes (mesh clients) behind a single firewall/router?</strong></dt><dd><p>Yes! As of version 0.7 Netmaker supports UDP Hole Punching to allow this, without the use of a third party STUN server!
|
||
Is UDP hole punching a risk for you? Well you can turn it off and make static nodes/ports for the server to refer to as well.</p>
|

</dd>
|

<dt><strong>What are the minimum specs to run the server?</strong></dt><dd><p>We recommend at least 1 CPU and 2 GB Memory.</p>
|
||
</dd>
|
||
<dt><strong>Does this support IPv6 addressing?</strong></dt><dd><p>Yes, Netmaker supports IPv6 addressing. When you create a network, just make sure to turn on Dual Stack.
|
||
Nodes will be given IPv6 addresses along with their IPv4 address. It does not currently support IPv6 only.</p>
|
||
</dd>
|
||
<dt><strong>Does Netmaker support Raft Consensus?</strong></dt><dd><p>Netmaker does not directly support it, but it uses <a class="reference external" href="https://github.com/rqlite/rqlite">rqlite</a> (which supports Raft) as the database.</p>
|
||
</dd>
|
||
<dt><strong>How do I uninstall Netmaker?</strong></dt><dd><p>There is no official uninstall script for the Netmaker server at this time. If you followed the quick-start guide, simply run <code class="docutils literal notranslate"><span class="pre">sudo</span> <span class="pre">docker-compose</span> <span class="pre">-f</span> <span class="pre">docker-compose.quickstart.yml</span> <span class="pre">down</span> <span class="pre">--volumes</span></code>
|

to completely wipe your server. Otherwise kill the running binary and it’s up to you to remove database records/volumes.</p>
