title: Is there a list of restricted ports for mobile devices and operating systems
body: <p>Firstly, thanks to everyone for help so far this community is terrific.</p>
  
  <p>I'm trying to obscure a normal http soap call to a device so that it doesn't use port 80. My only reason why is that the device doesn't do https.</p>
  
  <p>So I picked a random port (43) to address an intermediate server to send the message and discovered that the port is blocked on iOS and android.</p>
  
  <p>Is there a list that is readily accessible?</p>
  
  <p>Thanks in advance.</p>
