title: Can navigate to website from external network but can't from internal
body: <p>So here is my issue, I have a website hosted from a virtual machine on my server and am using a dyndns service to point a url to my IP. My ISP recently set up a new modem which unfortunately has its own built in gateway and router. After fighting it to forward port 80 I tested it by trying to navigate to the site via the URL and it didn't work, then I tested it on my phone connected to cell data network and it worked! I am able to visit the site via the URL as long as I am not connected to my network. i find this very weird and cannot figure out why.</p>
  
  <p>I am able to view the site on my network by typing in the local IP of the server.</p>
  
  <p>Any suggestions why this might be occurring?</p>
