Configuring WAN settings
5
NOTE
Be aware that the access point can (incorrectly) carry over previously configured static IP
information and maintain two connected routes once it gets an IP address from a PPPOE
connection.
5. Click Apply to save any changes to the WAN screen. Navigating away from the screen without
clicking the Apply button results in all changes to the screen being lost.
Enable Use the checkbox to enable Point-to-Point over Ethernet (PPPoE)
for a high-speed connection that supports this protocol. Most DSL
providers are currently using or deploying this protocol.
PPPoE is a data-link protocol for dialup connections. PPPoE allows
a host PC to use a broadband modem (DSL) for access to
high-speed data networks.
Username Specify a username entered when connecting to the ISP. When the
Internet session begins, the ISP authenticates the username.
Password Specify a password entered when connecting to the ISP. When the
Internet session starts, the ISP authenticates the password.
PPPoE State Displays the current connection state of the PPPoE client. When a
PPPoE connection is established, the status displays Connected.
When no PPPoE connection is active, the status displays
Disconnected.
Keep-Alive Select the Keep-Alive checkbox to maintain the WAN connection
indefinitely (no timeout interval). Some ISPs terminate inactive
connections. Enabling Keep-Alive keeps the Brocade Mobility
7131N-FGR Access Point’s WAN connection active, even when
there is no traffic. If the ISP drops the connection after an idle
period, the Brocade Mobility 7131N-FGR Access Point
automatically re-establishes the connection to the ISP. Enabling
Keep-Alive mode disables (grays out) the Idle Time field.
Idle Time (seconds) Specify an idle time in seconds to limit how long the Brocade
Mobility 7131N-FGR Access Point’s WAN connection remains
active after outbound and inbound traffic is not detected. The Idle
Time field is grayed out if Keep-Alive is enabled.
Authentication Type Use the Authentication Type menu to specify the authentication
protocol(s) for the WAN connection. Choices include None, PAP or
CHAP, PAP, or CHAP.
Password Authentication Protocol (PAP) and Challenge Handshake
Authentication Protocol (CHAP) are competing identify-verification
methods.
PAP sends a username and password over a network to a server
that compares the username and password to a table of
authorized users. If the username and password are matched in
the table, server access is authorized. WatchGuard products do
not support the PAP protocol because the username and password
are sent as clear text that a hacker can read.
CHAP uses secret information and mathematical algorithms to
send a derived numeric value for login. The login server knows the
secret information and performs the same mathematical
operations to derive a numeric value. If the results match, server
access is authorized. After login, one of the numbers in the
mathematical operation is changed to secure the connection. This
prevents any intruder from trying to copy a valid authentication
session and replaying it later to log in.
