In the first step of the wizard, you will be prompted to configure your web server URL. This is the URL that your team will use to access Burp Suite Enterprise Edition. It is also used to generate links back to the web UI, for example, in emails inviting users to activate their account.
Under "Web server URL", enter the URL of your web server, including the protocol and port number. This should be
http://your-web-server-IP:8080 or the fully qualified domain name of the machine on which you installed the web server.
You also have the option to set up a connection to your SMTP server if you want. However, you can leave these settings blank for now.
