Table 32 PPPoE Encapsulation
LABEL DESCRIPTION
ISP Parameters for Internet Access
Encapsulation The PPP over Ethernet choice is for a dial-up connection using PPPoE. The
ZyXEL Device 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. xDSL, 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.
User Name Type the user name given to you by your ISP.
Password Type the password associated with the user name above.
Retype to Confirm Type your password again to make sure that you have entered is correctly.
Nailed-Up
Connection
Select Nailed-Up Connection if you do not want the connection to time out.
Idle Timeout This value specifies the time in seconds that elapses before the router automatically
disconnects from the PPPoE server.
WAN IP Address Assignment
Get automatically
from ISP
Select this option If your ISP did not assign you a fixed IP address. This is the
default selection.
Use Fixed IP
Address
Select this option If the ISP assigned a fixed IP address.
My WAN IP
Address
Enter your WAN IP address in this field if you selected Use Fixed IP Address.
Remote IP
Address
Enter the remote IP address (if your ISP gave you one) in this field.
Remote IP
Subnet Mask
Enter the remote IP subnet mask in this field.
Metric This field sets this route's priority among the routes the ZyXEL Device uses.
The metric represents the "cost of transmission". A router determines the best route
for transmission by choosing a path with the lowest "cost". RIP routing uses hop
count as the measurement of cost, with a minimum of "1" for directly connected
networks. The number must be between "1" and "15"; a number greater than "15"
means the link is down. The smaller the number, the lower the "cost".
Private This parameter determines if the ZyXEL Device will include the route to this remote
node in its RIP broadcasts. If set to Yes, this route is kept private and not included in
RIP broadcast. If No, the route to this remote node will be propagated to other hosts
through RIP broadcasts.
