6.1.2 What You Need to Know About WAN
Encapsulation Method
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 PPPoA,
they should also provide a username and password (and service name) for user
authentication.
WAN IP Address
The WAN IP address is an IP address for the ZyXEL Device, which makes it
accessible from an outside network. It is used by the ZyXEL Device to
communicate with other devices in other networks. It can be static (fixed) or
dynamically assigned by the ISP each time the ZyXEL Device tries to access the
Internet.
If your ISP assigns you a static WAN IP address, they should also assign you the
subnet mask and DNS server IP address(es) (and a gateway IP address if you use
the Ethernet or ENET ENCAP encapsulation method).
