Change URL to Localhost

I have installed ISPConfig with a URL which does exist but runs on another server. Before I want to open my new server with this URL I do want to be able to get used to ISPConfig through my localhost.

Is there an easy way to change the URL to listen to to localhost?

Or do I need to resinstall the ISPConfig package?

Thanks

Harry

 

You don't need to change anything. Just go to http(s)://localhost:81
