The way to access to a specific port in IIS8, Windows 10 excepts 80 port?

I successfully implemented IIS 8 in Windows 10 and testing two Sites, named asSite A and Site B.

Site A:  The "Site A" is located in my IIS8 root folder and can be accessed to my default page "index.php" through " http : / / my ip address : 80 port ".

Site B:  The " Site B" path route is " C:\Users\hschoi\downloads\siteB\index.php".  It can be accessed through " http://localhost:1727"   but I can't access to the Site B default page through  "http:// my ip address:1727"   Of course I opened the 1727 port in windows firewall page; but, it never can't be accessed.  

Is there any solution to access to Site B ?

Thank you
