cannot access my webpage from outside (xampp)
<p><br>
I am trying to set up a web server with Xampp (ver 7.0.13) on my home PC. I redirect port 80 from router to my PC and Xampp is listening to port 80. Also, I change router's web server's port to 8080 in order to avoid conflict. <br><br></p>

<p>Result: I can access my <strong><em>helloworld.html</em></strong> on my pc and my phone. However, If i turn off my iphone wi-fi and using 4G network, I will not able to access dashboard and my <strong><em>helloworld.html</em></strong> by public ip (56.XXX.XXX.XXX/helloworld.html)  <br><br></p>

<p>I try :</p>

<ol>
<li>reinstall xampp</li>
<li>try different version off xampp</li>
<li>change config file >> Order deny,allow from all  (something like that</li>
<li>try to change  but  cannot be found in most of the config files. </li>
<li>change router port forward setting. 
<br></li>
</ol>

<p>But nothing work. What did I do wrong? ┐(´д`)┌</p>
