Configuring WAN Settings
A Wide Area Network (WAN) is a widely dispersed telecommunications network. The access point
includes one WAN port. The access point WAN port has its own MAC address. In a corporate
environment, the WAN port might connect to a larger corporate network. For a small business, the
WAN port might connect to a DSL or cable modem to access the Internet.
The Altitude 4710 Access Point supports an express card slot that can provide a secondary link in the
event of a wired WAN failure. The Altitude 4710's wired WAN is the primary WAN link, as long as it's
enabled and connected, and the WWAN interface functions as the secondary link.
For the WWAN to be a viable recovery solution, an Altitude 4710 must monitor the link status of the
wired WAN and check the health of the connection. If the Altitude 4710 detects the loss of the wired
WAN connection, it establishes the WWAN connection and updates the default gateway to the WWAN
interface. Additionally, the NAT rule is changed dynamically from the wired WAN interface to the
wireless WAN interface. All traffic that used go to the wired WAN is redirected to the WWAN. If the
Altitude 4710 detects the wired WAN link is restored and up for at least 1 minute, the operation is
reversed. The wired WAN becomes the default WAN link once again.
Use the WAN screen to set the WAN IP configuration, Point-to-Point Protocol over Ethernet (PPPoE)
parameters and the Altitude 4710.
NOTE
The WAN port is not enabled until the AP4700 is powered by an 802.3at POE supply.
