PPPOE

PPPoE (Point-to-Point Protocol over Ethernet) allows a point-to-point connection
while using Ethernet. Just like the dial up protocol on which it is based, PPPoE
can use traditional user name and password authentication to establish a direct
connection between two Ethernet devices on a network (e.g., your AirLink
gateway and your computer or router).
examples for PPPoE with your AirLink gateway:
• Backup connectivity solution for your network
• Individualized Internet connection on a LAN
• Password restricted Internet connection
Only one computer, router, or other network device at a time can connect to the
AirLink gateway using PPPoE. If you are using the AirLink gateway connected to
a router as a back up Internet connection for your network, you should configure
the router to use the PPPoE connection and not the individual computers.
Note: To configure a PPPoE connection on some operating systems, you need adminis-
trator privileges to the computer you are configuring or access granted by an administrator
on the network to add/remove devices to your computer.
