As the number of these remote sites grow, the number of Site-to-Site links needed will grow exponentially. If you have to maintain a gateway server or device for the Site-to-Site connections and another gateway for remote access such as VPN or DirectAccess, the maintenance cost associated with it can increase dramatically.
