title: Camel Netty UDP listener listening on 0.0.0.0 and not receiving packets
body: <p>I'm new to Camel, Netty and UDP, but I've been researching this for a while and still can't figure out what's going on.</p>
  
  <p>All I'm trying to do is implement a UDP listener using Camel and Netty (currently on Windows 7, but will be moving the project to Linux). My spring config is as follows:</p>
  
  <pre><code>&lt;camel:camelContext id="test"&gt;
      &lt;camel:route&gt;
          &lt;camel:from uri="netty:udp://localhost:5150?sync=false"/&gt;
          &lt;camel:to uri="log:cameltest?level=DEBUG"/&gt;     
          &lt;camel:to uri="file://outbox"/&gt;
      &lt;/camel:route&gt;
  &lt;/camel:camelContext&gt;
  </code></pre>
  
  <p>The listener appears to starts fine (running through Eclipse). However, when I do a netstat, I see this:</p>
  
  <pre><code>UDP    0.0.0.0:5150
  UDP    [::ffff:127.0.0.1]:5150
  </code></pre>
  
  <p>when I am expecting it to be listening on 127.0.0.1. Nothing I've read online is clear on if this is expected behavior for Camel/Netty/UDP.</p>
  
  <p>I'm testing this by sending from a Java NIO UDP Client. If an NIO UDP Server is listening, it receives the packet fine (all done through localhost).</p>
  
  <p>I also tested a Camel/Netty/TCP listener and that works fine.</p>
  
  <p>Why is the listener listening to all local addresses? And if so, why isn't it receiving my packet from localhost? </p>
