title: How to open port 2195 in iptables CentOS 6 for activating the APNS
body: <p>I tried this solution:</p>
  
  <pre><code>iptables -I OUTPUT -p tcp --dport 2195 -j ACCEPT
  /etc/init.d/iptables stop
  /etc/init.d/iptables start
  </code></pre>
  
  <p>but still can't access the port.</p>
  
  <p>If there are more ports that I have to open for APNS let me know.</p>
