A WAN (Wide Area Network) connection is an outside connection to another network or the Internet. It 
connects your private networks (such as a LAN (Local Area Network) and other networks, so that a 
computer in one location can communicate with computers in other locations.

Encapsulation is used to include data from an upper layer protocol into a lower layer protocol. To set up 
a WAN connection to the Internet, you need to use the same encapsulation method used by your ISP 
(Internet Service Provider). If your ISP offers a dial-up Internet connection using PPPoE (PPP over 
Ethernet) or PPTP (Point-to-Point Tunneling Protocol), they should also provide a username and password 
(and service name) for user authentication.
