In previous VS, you modify the applicationhost.config file in /documents; but now in VS2015 they moved this file into the .vs file in the project folder.
But modifying
<bindings>
<binding protocol="http" bindingInformation="*:43071:10.103.123.025" />
</bindings>
then go into firewall settings and add an exception with the port number, run, open browser and type in 10.103.123.025:43071 and there is the website. anyone on the local network could access it fine.
in the OLD visual studio it worked. in VS2015 it fails, click Run, few seconds a popup dialog with: port 12345 is not running click Here for information about (something). i looked at every link and still dont understand what it takes to make the VS2015 iis express allow external web pages
