127.0.0.1 is working BUT own ip is not working?

When i type web browser 127.0.0.1 than freepbx is opening. But when i type 10.0.0.100 (my ip address) freepbx web interface does not appear. It says “it s working”. What is the reason?

After login to FreePBX page, go to System Admin -> Network settings. here you can configure your static IP address and network. Set IP Protocol to None.
