PPPoE Override Configuration
Profile Interface Override Configuration
PPP over Ethernet (PPPoE) is a data-link protocol for dialup connections. PPPoE allows the access
point to use a broadband modem (DSL, cable modem, etc.) for access to high-speed data and
broadband networks. Most DSL providers support (or deploy) the PPPoE protocol. PPPoE uses
standard encryption, authentication, and compression methods as specified by the PPPoE
protocol. PPPoE enables controllers, service platforms and Access Points to establish a
point-to-point connection to an ISP over existing Ethernet interface.
To provide this point-to-point connection, each PPPoE session learns the Ethernet address of a
remote PPPoE client, and establishes a session. PPPoE uses both a discover and session phase to
identify a client and establish a point-to-point connection. By using such a connection, a Wireless
WAN fail over is available to maintain seamless network access if the access point’s Wired WAN
were to fail.
NOTE
Devices with PPPoE enabled continue to support VPN, NAT, PBR and 3G fail over on the PPPoE
interface. Multiple PPPoE sessions are supported using a single user account user account if
RADIUS is configured to allow simultaneous access.
NAT Direction Define the Network Address Translation (NAT) direction. Options include:
Inside - The inside network is transmitting data over the network its intended destination. On the way
out, the source IP address is changed in the header and replaced by the (public) IP address.
Outside - Packets passing through the NAT on the way back to the controller or service platform
managed LAN are searched against to the records kept by the NAT engine. There, the destination IP
address is changed back to the specific internal private class IP address in order to reach the LAN over
the network.
None - No NAT activity takes place. This is the default setting.
IP Inbound Firewall
Rules Use the drop-down menu to select an inbound IP ACL to associate with traffic on the WAN backhaul. If
an appropriate IP ACL does not exist, select the Add button to create a new one.
VPN Crypto Map If necessary, specify a crypto map for the wireless WAN. A crypto map can be up to 256 characters long.
If a suitable crypto map is not available, click the Create button to configure a new one.
WWAN Default Route
Priority Use the spinner control to define a priority from 1 - 8,000 for the default route learned by the wireless
WAN. The default value is 3000.
