title: How to remove existing ip tunnel
body: <p>I create ip tunnel in centos linux with this link <a href="http://www.techonia.com/create-tunnel-interface-linux" rel="nofollow">http://www.techonia.com/create-tunnel-interface-linux</a>.</p>
  
  <p>Then I want to delete the existing tunnel, I think I have already delete with command ip tunnel del "device".  But why the port is still cannot be accessed? or maybe I am wrong when do the deletion?  the port i used for tunneling before is 1433 (sql server).</p>
