When you performed the initial configuration, you set up your network settings to get started with Burp Suite Enterprise Edition. However, if your circumstances change, you might need to change your network settings accordingly.
For example, you might decide you want to start using TLS for communication with the web server or your organization may change its security policy and require you to access the public web using a proxy.
To make changes to your network settings, click the burger menu and go to "Settings" > "Network". For information, please refer back to the initial configuration documentation.
