I was in two minds about whether this post belongs on Stack Overflow or Server Fault so if I have the wrong area then apologies! I chose Server Fault as I believe the only difference between a previous working solution and the current issue I have is IIS Express.
I have successfully used SPI Port Forward to test local websites mid-development when using Visual Studio 2010 but with the upgrade to Visual Studio 2013 and the inclusion of IIS Express I am no longer able to see my website when browsing from another device on the same network. As you can imagine such functionality is priceless when testing on mobile devices as it means I don't have to publish the site anywhere before testing.
Any ideas?
