title: Ssh into server from within ZeroTier network only
body: <p>I would like:</p>
  
  <p>1) all devices within a ZeroTier network to be able to ssh into each other via ZeroTier IPs.</p>
  
  <p>2) No devices from outside the network to be able to ssh into the network neither via ZeroTier IPs or standard public IPs.</p>
  
  <p>The issue is that in spite of having my devices on the same ZT network, I can still ssh into those via public IP. How do I prevent this? </p>
  
  <pre><code>IP address for eth0:            104.xxx.xx.xxx (public IP) 
  -&gt; should not be able to ssh using this IP
  
  IP address for ztxxxxxxxx:      10.xxx.xx.xx (ZeroTier IP)
  -&gt; should be able to ssh using this IP
  </code></pre>
  
  <p>Many thanks.</p>
