PPPoE
Choose this option if your ISP uses PPPoE (Point-to-Point Protocol over Ethernet)
to establish Internet connections (typical for DSL lines). Then enter the settings
provided by your ISP:
• Username and Password —Username and password for your ISP account.
The maximum number of characters for each entry is 255.
• Service Name —A set of services provided by the ISP identified by the
service name.
• Connection Timers —Connection is disconnected after a period of
inactivity.
- Connect on Demand —When this feature is enabled, the device
automatically establishes your connection. If you enabled this feature,
enter the
Max Idle Time , the number of minutes that the connection can
be inactive before the connection is terminated. The default maximum
idle time is 5 minutes.
- Keep Alive —Ensures that your router is always connected to the
Internet. When this feature is selected, the router keeps the connection
alive by sending out a few data packets periodically. This option keeps
your connection active indefinitely, even when the link sits idle for an
extended period of time. If you enable this feature, also enter the
Redial
Period to specify how often the router verifies your Internet connection.
The default period is 30 seconds.
• Use the Following DNS Server Addresses —Enables obtaining connection
information from DNS servers.
• DNS Server 1 and DNS Server 2— IP address of the DNS servers.
Optionally, you can enter a second DNS server. The first available DNS
server is used.
• MTU —Maximum transmission unit ( MTU ) size. Select Auto to set the size
automatically. Otherwise, to set the MTU size manually, select Manual and
enter the MTU size. (The size in bytes of the largest protocol data unit that
the layer can pass.)
