title: Cannot access with IP from other devices, localhost server on MAC
body: <p>I have set the default localhost server to run on my MAC with apache with the default settings. I can access the local server using localhost and the IP from the server it self but cannot access from another PC using the IP connected on the same WIFI network with a simple router.
  I have disabled the firewall on mac but nothing.
  This is my /etc/hosts file:</p>
  
  <pre><code>127.0.0.1   localhost
  255.255.255.255   broadcasthost 
  ::1             localhost 
  </code></pre>
  
  <p>The mac IP on wifi is 192.168.10.102, the other PC IP is 192.168.10.105
  Apache is set to listen on port 80, http.conf</p>
  
  <pre><code>Listen 80
  </code></pre>
  
  <p><code>sudo tcpdump -i en0</code> result:</p>

  <p><strong>NOTE</strong> 
  While restarting the MAC computer for a couple of seconds I am able to access the localhost server with IP from the other computer...
  Also the MAC has installed Symanctec End Point Protection which I cannot find a way to disable it even I have sudo permissions.</p>
  
  <p>Any ideas?</p>
