How To Setup The EdgeXOS Using PPPoE Links
This document provides an overview as to how to use a PPPoE connection with the
EdgeXOS appliances. PPPoE stands for point-to-point over Ethernet, and is
commonly used with DSL links. XRoads Networks once supported PPPoE directly
however it was found that internationally there were different implementations of the
standard and thus at times the PPPoE link would become unstable.
Due to these stability issues, XRoads Networks decided that it was best to allow the
ISP’s DSL modem to terminate the PPPoE link and to simply pass the Layer-3
connectivity to the EdgeXOS appliance.
The following is a step-by-step process for installing a PPPoE connection.
A) Setting Up The DSL Modem
As shown below, there are many different types of DSL modems, however when
the ISP is using PPPoE they will all have the ability to terminate the PPPoE
protocol and pass a private IP address to the LAN side of the modem.
Technically in this configuration the modem is acting more like a router and is
NATing the public IP address it receives via the PPPoE link to a private IP
address which is passed to the EdgeXOS device on the LAN side of the DSL
modem/router.
NOTE: If you have the option when ordering the DSL service, make sure to request
a DSL modem/router or DSL router, over a device which ONLY supports bridging.
Nearly all DSL services come with modem/routers today.
