Point-to-Point Protocol over Ethernet (PPPoE) allow mbox to dial to ISP DSL service through an ethernet connection. PPPoE is getting less popular now but still exists in some countries.

In order to connect to PPPoE, we just need to connect mbox ethernet port to a DSL modem (with RJ45 connection) and input the given username & password (provided by ISP).

When configuring PPPoE interfaces, please note:

• • Usually, ISP will set DNS and default gateway for a PPPoE router. But mbox by default doesn't access DNS given by ISP, so you need to explicitly configure DNS by "ip name-server x.x.x.x y.y.y.y"

  • You can use the optional "default" command to accept default route given by ISP.

  • mbox supports connecting to multiple PPPoE connection (each ethernet interface connect to different ISP DSL modem), once PPPoE connection is dialed up, each connection will create a virtual PPP interface, if you have multiple PPPoE, the virtual interfaces will be named as ppp0, ppp1.... use "show ip interface brief" to find out the newly created ppp interfaces.

  • the PPPoE related commands are entered under the ethernet interface connecting to respective ISP DSL links

    • <username> username to for the PPPoE dial, given by ISP

    • <password> password to for the PPPoE dial, given by ISP

    • default (optional) accept default route given by ISP. Do NOT use this option if you have multiple WAN connections (usually you will configure MWAN with multiple WAN connections).

SAMPLE CONFIG

NOTE: when using PPPoE with Multi-WAN config, there're a few points to note:

1. the next-hop is usually dynamic or unknown, so in the MWAN config, use ppp0/ppp1 as next-hop, eg. 

2. the MWAN config is applied under ppp interface config, eg. 

Attached below is a sample config for configuring MWAN with PPPoE,  where mbox is connecting to two ISPs, eth0 to ISP1 using fiber/ONT; eth1 to ISP2 using PPPoE/DSLModem.
