Primary WAN Interfaces
1. WAN refers to the Ethernet WAN port on the LAN-Cell which is typically connected
to a DSL/cable modem, T1, or other high-speed Ethernet-based wired Internet service.
2. CELLULAR refers to 3G cellular (CDMA/GSM) modem cards that are inserted into
the PC-Card slot on the side of the LAN-Cell.
The primary WAN interfaces can be used in either Load-Balancing or Fail-Over modes and
are the most common pathways for connecting to the Internet.
Backup WAN Interfaces
1. Dial-Backup refers to the AUX (serial) port the LAN-Cell which can be connected to
an external serial modem that responds to basic Hayes “AT” commands. The Dial-
Backup port is used when the wired Ethernet WAN (or CELLULAR) interface is not
available.
2. Traffic Redirect refers to the LAN-Cell’s ability to redirect WAN-bound traffic to an
independent WAN gateway located elsewhere on the Local Area Network. This is a
“route of last resort” in situations where the LAN-Cell has no available WAN
connections of its own.
5.1.1 What You Can Do in the WAN Screens
• Use the General screen (Section 5.2 on page 94) to configure load balancing, route
priority, and connection test settings for the LAN-Cell.
• Use the WAN screen (Section 5.3 on page 103) to configure the Ethernet WAN interface
for Internet access on the LAN-Cell.
• Use the Cellular (3G) screen (Section 5.4 on page 114) to configure the CELL interface
for Internet access on the LAN-Cell.
• Use the Traffic Redirect screen (Section 5.5 on page 120) to configure an alternative
gateway.
• Use the Dial Backup screen (Section 5.6 on page 122) to configure the backup WAN
dialup connection.
