Select Automatic from the Link Speed drop-down list to have
the Edge select the best network speed, or select a static link
speed that you know is compatible with your equipment.
We recommend that you set the link speed to Automatic unless you
know this setting is incompatible with your equipment.
Advanced PPPoE Settings
The Quick Setup Wizard allows you to set up basic PPPoE settings. If
necessary, you can also configure more advanced parameters:
Service Name
Use this field to add a service name. The Edge only starts with
access concentrators that support the specified service. This
option is not usually used. Use it only if there is more than one
access concentrator or you know that you must use a specified
service name.
Access Concentrator Name
Use this field to identify a PPPoE server, known as an access
concentrator. The Edge only starts a session with the access
concentrator you identify in this field. This option is not usually
used. Use it only if you know there is more than one access
concentrator. If you enter a Service Name and Access
Concentrator Name, you must use the same value for the Edge to
negotiate a PPPoE session.
Use Host-Uniq tag in PPPoE discovery packets
Select this option if there is more than one installation of the
same PPPoE client on the network. This can prevent interference
between the discovery packets of each client. This is not a
supported Edge feature; WatchGuard includes this option to
make the Edge compatible with ISPs which have this
requirement.
Authentication retries
This field controls the number of times the Edge tries to send
PAP authentication information to the PPPoE server. The default
value of None is sufficient for most installations. You must enter
a high value to make the Edge compatible with some ISPs.
Use LCP echo request to detect lost PPPoE link
When you enable this check box, the Edge sends an LCP echo
request at regular intervals to the ISP to make sure that the
PPPoE connection is active. If you do not use this option, the
