External Network Advanced Settings - Watchguard Firebox X20E User Manual

In the Inactivity Time-out field, type the number of minutes before the Firebox X Edge
4
disconnects the active PPP0E connections.
We recommend a value of 20. If you set this value to 0, no timeout will occur.
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 only with access concentrators
that support 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 a PPPoE server, known as 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
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.
