How to set server ip in suitecrm

I installed the suite crm in Xampp virtual server on local, but now i want to access this suitecrm from my another pc over the internet, i check the http files of Apache server and set the public IP in it but i’m not able to do, so can you please help me out from this.

Can you access the XAMPP site?
Just place an Hello world index.htm file inside the directory to test.
You can create a sample file (use index.htm not index.html)
see http://pubs.vmware.com/vfabric53/index.jsp?topic=/com.vmware.vfabric.tc-server.2.9/getting-started/tutwebapp-index-html-file.html

Then remove the file and go for SuiteCRM: you will need to change the config.php (value ‘db_host_name’ and ‘host_name’ and ‘site_url’ )
