Appendix B DSLAAU Manual

Point-to-Point Protocal over Ethernet

PPPoE (Point-to-Point Protocol over Ethernet) is a specification for connecting multiple computer users on an Ethernet to a remote site through common customer premises equipment. PPPoE can be used to have an office or building-full of users share a common DSL (Digital Subscriber Line) connection to the Internet. PPPoE combines the Point-to-Point Protocol commonly used in dialup connections, with the Ethernet protocol, which supports multiple users in a local area network.The PPP Protocol information is encapsulated within an Ethernet frame.

corega DSLAAU supports PPPoE for WAN and LAN applications, as presented in this section.

•PPPoE for WAN Applications

PPPoE support is embedded into the WAN driver making the mo- dem appear as a dial-up modem to the operating system. Dial-Up Networking is used to establish a connection.

Follow the installation instructions provided in this manual when implementing PPPoE with the WAN driver.

•PPPoE for LAN Applications

PPPoE is supported via third party software when implemented with a LAN driver, making the modem appear as a local area network (LAN) device to the operating system. It allows multiple computer users on an Ethernet to share a common DSL connection to the Internet.

After installing the LAN driver, follow the installation instructions
