Encapsulation
The PPPoE choice is for a dial-up connection using PPPoE. The router supports
PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF standard (RFC
2516) specifying how a personal computer (PC) interacts with a broadband modem
(i.e. DSL, cable, wireless, etc.) connection. Operationally, PPPoE saves significant
effort for both the end user and ISP/carrier, as it requires no specific configuration of
the broadband modem at the customer site. By implementing PPPoE directly on the
router rather than individual computers, the computers on the LAN do not need
PPPoE software installed, since the router does that part of the task. Further, with
NAT, all of the LAN's computers will have access.
Service Name

(Network
Address
Translation)
Network Address Translation (NAT) allows the translation of an Internet protocol
address used within one network (for example a private IP address used in a local
network) to a different IP address known within another network (for example a
public IP address used on the Internet).
Select this checkbox to enable NAT.
