Pptp Encapsulation - ZyXEL Communications ZyWALL 5 User Manual

ZyWALL 5 Internet Security Appliance
LABEL
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 Draft 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 Type the PPPoE service name provided to you. PPPoE uses a service name to identify
and reach the PPPoE server.
Nailed-Up Select Nailed-Up if you do not want the connection to time out.
Idle Timeout This value specifies the time in seconds that elapses before the ZyWALL automatically
disconnects from the PPPoE server.

7.4.3 PPTP Encapsulation

Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables secure transfer of data
from a remote client to a private server, creating a Virtual Private Network (VPN) using TCP/IP-based
networks.
PPTP supports on-demand, multi-protocol and virtual private networking over public networks, such
as the Internet. The screen shown next is for PPTP encapsulation.
