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. Refer to the WWAN Settings field (located at the bottom of the WAN screen) to enable WWAN
failover operation and define user names and passwords for WWAN card users.
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 Mobility
7131 Access Point’s WAN connection active, even when there is no traffic. If the ISP drops
the connection after an idle period, the Mobility 7131 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 Mobility 7131 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.
