1.11. PPPoE configuration
The SPECTRE 3G router does not support the PPPoE configuration option.
PPPoE (Point-to-Point over Ethernet) is a network protocol where PPP frames are
encapsulated in Ethernet frames. The PPPoE feature in the SPECTRE RT industrial router
operates in client mode. The router will connect to a PPPoE server or a PPPoE bridge device
such as an ADSL modem.
To enter the PPPoE configuration, select the PPPoE menu item. If the Create
PPPoE connection option is selected, the router will attempt to establish a PPPoE
connection on power up. The PPPoE client will connect to devices that support either a
PPPoE bridge or a PPPoE server. After a PPPoE connection is established, the router
obtains the IP address of the PPPoE Server device and all communications from the device
are forwarded to the industrial router.
