Page numbering is a function of sections. The numbering is changed in the Format Page Numbers dialog. Insert > Page Numbers > Format Page Numbers.

You can tell sections to start on an even or odd page. Doing this will create a blank page (no header/footer) if needed.

It is unusual to restart page numbers at the beginning of each section.
