48 WatchGuard Firebox X Edge
7 Type the PPPoE password supplied by your ISP.
8 Type the time delay before inactive TCP connections are
disconnected.
9 If appropriate, select the Automatically restore lost
connections checkbox.
This option keeps a constant flow of traffic between the Firebox and the
PPPoE server. This allows the Firebox to keep the PPPoE connection open
during a period of frequent packet loss. If the flow of traffic stops, the
Firebox reboots. A reboot frequently restores the connection. The ISP
sees this constant flow of traffic as a continuous connection. The
regulations and billing policy of the ISP determine whether you can use
this option.
10 Select the Enable PPPoE debug trace checkbox to activate
PPPoE debug trace.
This can assist WatchGuard Technical Support in troubleshooting PPPoE
problems.
11 Click Submit.
Configuring the Trusted Network
You can set the trusted network to use either the Firebox® X Edge’s
internal DHCP server or you can use static addressing. You can also
change the IP address of the trusted network.
By default, the Firebox DHCP server is enabled. The Firebox trusted
network starts with IP address 192.168.111.1 and is a class C net-
work using subnet mask 255.255.255.0. In other words, the Firebox
can distribute up to 251 additional, unique network addresses from
192.168.111.2 to 192.168.111.252. In addition, the Firebox by
default uses the same DNS and domain information as it receives
from your service provider.
For more information on IP addressing, see “IP Addresses” on
page 5.
If you want to use a DHCP server other than the one packaged with
the Firebox X Edge, disable the Firebox X Edge DHCP server. If you
want to forward DHCP requests to a remote DHCP server through a
relay agent, enable the DHCP Relay option as described in “Config-
uring the Firebox as a DHCP relay agent” on page 51.
