Advanced PPPoE settings

The Quick Setup Wizard allows you to set up basic PPPoE settings. If necessary, you can also configure more
advanced settings. Click Submit when you have completed the configuration of the Advanced PPPoE
settings.
Service Name
Use this field to add a service name. The Firebox X Edge starts a session only with a PPPoE server,
known as an access concentrator, that supports the specified service. Usually, this option is not used.
Use this field 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 an access concentrator. The Firebox X Edge starts a session only with the
access concentrator you identify in this field. Usually, this option is not 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
Firebox X Edge feature; this option is included to make the Edge compatible with ISPs that have this
requirement.
Authentication retries
This field controls the number of times the Firebox X 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 select this check box, the Firebox X 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 Edge must
get a PPPoE or PPP session termination request from the ISP to identify a broken connection.
LCP echo interval
When you enable LCP echoes, this value sets the interval between LCP echo requests sent by the
Firebox X Edge to the ISP. The more frequently the LCP echo requests are sent, the faster the Edge can
identify a broken link. A shorter interval uses more bandwidth on the external interface, but even the
shortest interval does not significantly decrease performance.
LCP echo retries
When you enable LCP echoes, this value sets the number of times the Firebox X Edge tries to get a
response to an LCP echo request before the PPPoE connection is considered inactive. If an ISP does
not send a reply to three LCP requests, there is a low probability that it will reply to subsequent LCP
echo requests. In most cases, the default setting of three is the best.
Enable PPPoE debug trace
WatchGuard Technical Support uses this check box to troubleshoot PPPoE problems. With this
option on, the Firebox X Edge makes a file that you can send to Technical Support. Use this option
only when Technical Support tells you because it decreases Edge performance.
