PPPoE on MX
Cisco Meraki MX Security Appliances and Z-Series Teleworker Gateways support Point to Point Protocol over Ethernet (PPPoE). You may need PPPoE if your ISP requires a username and password to access your DSL connection. PPPoE can be configured on the device's Local Status Page, under the Configure tab by setting the Connection type to PPPoE:
Please note that standard PPPoE is not supported by Cisco Meraki MR Series Access Points (though client-side PPPoE is, see below). A successful workaround for MR Series Access Points is to use a security appliance or router (such as a Cisco Meraki MX, Linksys, Netgear or D-Link) that supports PPPoE and then connect the Cisco Meraki AP to one of the LAN Ethernet ports. Cisco Meraki recommends turning off the wireless functionality of the non-Meraki routers that have wireless capabilities.
Client-side PPPoE on MR
Cisco Meraki MR APs support client-side PPPoE connections. So any client connected wirelessly or wired to an MR AP can connect to a PPPoE server on the remote end. This feature is enabled by our support team on a per network basis.
Note that MR devices themselves cannot currently use PPPoE as a connection type, they simply pass PPPoE traffic/client-side connections.
Note: Client PPPoE function can only be used for MR APs running firmware 25.12 or higher. Also, PPPoE is unrelated to Power over Ethernet (PoE).
