Wanted to connect a LTE modem to the MX but looking at the documentation. It seems that in Canada only a few devices are supported.
I want to use Cypress Oxygen-3 modem. If only USB ports are available for the second WAN port, could I not use a USB to Ethernet dongle and will this work!
Do you want to use the device as an active secondary WAN connection or just for failover?
Do you have a single WAN connection or redundant WAN connections currently?
Yes, you nailed it. I will be using this is an Ethernet active-active network design. The Cypress Oxygen 3 is a LTE gateway that will connect to the carriers wireless APN via a static IP. The only drawback to these are the constant keepalives so I'm anticipating about 2Gigs of data monthly. Unless I'm missing something here, I believe the USB connection would be active-failover which I believe can take up to 3 minutes to build the IPSec tunnel (VPN) and since this would be a PoS environment, this design is not an option.
Now, I have heard in the grapevine that Meraki will be bringing SIM supported LTE models this year. This being the case, would solve everything.
The USB is really only for a last ditch failover if WAN1 and WAN2 are down.
Othwerise I prefer cradlepoint devices. They work well to reliably convert cellular network to ethernet.
I'm with @AjitKumar - don't use the USB devices because they are a real pain. Get an LTE hot spot that has Ethernet ports, and plug it into a WAN port.
