Configuring the External Network
User Guide 49
To set your Firebox to use PPPoE on the external interface:
1 Use your browser to connect to the System Status page. From

The External Network Configuration page appears.
2 From the Configuration Mode drop-down list,
select PPPoE Client.
3 Type the Name and Password in the related fields. Get this

the myname section in the Name field. Type the ispdomain section in
the Domain field. Do not type the @ symbol. Some ISPs do not use the
Domain.

check box.
