Thanks @PhilipDAth , Will Meraki support this setup where there are no primary connections in WAN1 & WAN2? I know Cradlepoint has external devices that can use LTE and present a wired WAN links (Where Cradlepoint handles the failover) - Would this be a more supported approach? @PhilipDAth wrote: >We have an offering on the table for MX67C using LTE as a Primary for SD-WAN with no WAN links - I note that the datasheet supports LTE as a failover only. The FAQ also says this is not to be used for SD-WAN.   Before you can use the LTE as a primary you have to plug it into a fixed-line connection to allow a firmware upgrade.  Despite what the documentation says, you can use it only with LTE after that.  It will form AutoVPN connections without issue.       ...

    @PhilipDAth wrote:   If you plug in a USB cellular modem (or use an MX67C with a SIM card) the cellular connection is kept offline until the primary ISP circuits fail.  So it does not use any traffic.  You can't use these backup circuits for SD-WAN (except strictly in the sense of failover).  Hi @PhilipDAth ,   We have an offering on the table for MX67C using LTE as a Primary for SD-WAN with no WAN links - I note that the datasheet supports LTE as a failover only. The FAQ also says this is not to be used for SD-WAN.   From the FAQ at: MX67_and_MX68_Overview_and_Specifications#FAQ  Is this SD-WAN over LTE? No. Can LTE be used as the primary uplink? No, LTE is currently only supported as a fail-over link and should only be primary during a temporary WAN failure event.   The offering seems to be an unsupported design. Would like to know your thoughts (and Meraki technical - if they see this) .   Thanks Cheers ... View more
