CONFIGURING FOR PPPOE SUPPORT
Follow the procedure below if your ISP requires PPPoE support.
If you use a cable modem or DSL to connect to the Internet, you
may need this feature enabled. To complete this configuration
process, you will need the following information from your ISP:
• Your user name and password for your ISP account
• The Maximum Transmission Unit (MTU) supported by

can be transmitted as a single packet. (Any packets
larger than this number will be broken into multiple
packets before transmission.)
• The IP address of the Domain Name System (DNS)
server used by the ISP. (You can also configure the

Keep-Alive field, then enter the number of seconds that
should pass before the router sends out a packet. For
example, if you enter 45 seconds, the router will transmit a
