Just add the submenu with the "Router" and "Firewall" entries to the
filemenu in the same way you added the submenu with the "New", "Open", and
"Exit" entries to the menu bar:

new_menu = Menu(filemenu)
new_menu.add_command(label="Router")
new_menu.add_command(label="Firewall")
filemenu.add_cascade(label="New...", menu=new_menu)
