4.2.4 PPPoE and PPPoA Connection for WAN
Follow the instructions below to configure the Router to use a PPPoE or PPPoA for the Internet
connection. Make sure you have all the necessary information before you configure the WAN connection.
Figure 4-7 WAN Settings Menu – PPPoE/PPPoA
1. Under the ATM Interface settings at the top of the menu (including VPI, VCI, and Virtual Circuit) 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 ATM Interface 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.
2. 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.
3. 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.
4. Leave the MTU value at the default setting (default = 1400) unless you have specific reasons to change
this (see table below).
5. Leave the MRU value at the default setting (default = 1492) unless you have specific reasons to change
this (see table below).
6. 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.
