To set up a PPPoE or PPPoA connection:
1. If not already selected, choose the PPPoE/PPPoA option from the WAN Settings pull-down menu.
PPPoE/PPPoA is selected by default if you are configuring the Router for the first time.
2. Under the ATM VC Settings at the top of the window should not be changed unless you have been instructed to
change them. However, if you are instructed to change the VPI or VCI values, type in the values assigned for your
account. Leave the PVC and Virtual Circuit setting at the default (Pcv0 and Enabled) values for now. This can be
used later if you are configuring multiple virtual circuits for your ADSL service. For more information on ATM
VC Settings, see the table on page 32 below.
3. Under the PPPoE/PPPoA heading, type the User Name and Password used for your ADSL account. A typical
User Name will be in the form user1234@isp.co.uk. The Password may be assigned to you by your ISP or you
may have selected it when you set up the account with your ISP.
4. Choose the Connection Type from the pull-down menu located under the User Name and Password entry fields.
This defines both the connection protocol and encapsulation method used for your ADSL service. The available
options are PPPoA VC-Mux, PPPoA LLC and PPPoE LLC. If have not been provided specific information for the
Connection Type setting, leave the default setting.
5. Leave the MTU value at the default setting (default = 1400) unless you have specific reasons to change this (see
table below).
6. Leave the MRU value at the default setting (default = 1492) unless you have specific reasons to change this (see
table below).
7. Leave the Default Route enabled if you want to use the Router as the default route to the Internet for your LAN.
Whenever a computer on the LAN attempts to access the Internet, the Router becomes the Internet gateway to the
computer. If you have an alternative route for Internet traffic you may disable this without effecting the Router's
connection.
8. NAT should remain Enabled. If you disable NAT, you will not be able to use more than one computer for Internet
connections. NAT is enabled and disabled system-wide, therefore if you are using multiple virtual connections,
NAT will disabled on all connections.
9. The Firewall should remain enabled for most users. If you choose to disable this you will not be able to use the
features configured in the Firewall Configuration and Filters windows located in the Advanced directory. See
the next chapter for more details on these windows.
10. Typically the globally IP settings (i.e. IP address for the WAN interface) for a PPPoA or PPPoA connection will
use Dynamic IP assignment from the ISP. Some accounts may be assigned a specific global IP address. If you
have been give an IP address for you PPPoE/PPPoA connection, select the Static IP option from the IP Control
pull-down menu. This menu can be used to configure the WAN port as an Unnumbered IP interface. (See table
below for Unnumbered IP).
11. Choose the desired Connection Setting. Select from: Always ON, Connection On Demand, or Manual. Most
users will want to choose the default connection setting, Always ON.
12. Most users will not need to change ATM settings. If this is the first time you are setting up the ADSL connection
it is recommended that you leave the Service Category settings at the default values until you have established the
connection. See the table on page 29 for a description of the parameters available for ATM traffic shaping.
13. When you are satisfied that all the WAN settings are configured correctly, click on the Apply button.
14. The new settings must be saved and the Router must be restarted for the settings to go into effect. To save and
reboot the Router, click on the Tools directory tab and then click the System button. In the System Settings
window, click the Save and Reboot button under Save Settings and Reboot the System.
15. Click OK when the following "Save and restart?" dialog box opens.
