2) Edit the Site Template > Add a portlet - WCD for example
3) Configure the portlet > Add all of the Guest Permissions
4) Export the portlet with the Permissions checked
5) Create a new Site Template
6) Import the previously exported portlet with the Permissions checked option
7) Check the imported portlet's permissions

Result: All of the Guest Permissions are unchecked
