How to make TFS url public so that any one can access

I Installed TFS on my machine and the URL I have is as follows http://my-pc:8080/tfs I configured this using network account. So is there any possibility so that I need to share the url to some one who can access my code and use it

 

 

I have gone through this link but no luck
