WordPress Keeps redirecting to the old development server IP Address instead of the new development IP Address

I am little bit newbie for WordPress. I have been developing website on my local machine using word press but it has come to a time where we have to migrate the website to client server with a public IP address. The computer is behind router. All the port forwarding are done. I even manage to access wp-admin page. However when I tried to access the main website I can't because it keeps redirecting the public IP to a local IP or to the first development IP address. Note that I have changed the general setting to the public IP address.

Thank you for your help
