OpenVPN Configuration for Inseego MiFi Pro X HotSpot (M3000)

[evanevery]

I've been trying to find a portable 5G wifi hotspot router which will establish a VPN tunnel back to my network.  I have a couple of GL.inet devices but the only PORTABLE product I can find which provides BOTH 5G and OpenVPN is the Inseego M3000.  So I purchased one.

I've been banging away all morning on the OpenVPN config options and exporting OVPN config files but the M3000 just keep rejecting the config with "Invalid Configuration File" and a not-so-helpful "Please correct the issue" message while never specifically saying what it is unhappy about (and you have to have a valid VPN config BEFORE you can see the VPN log files...)  I've Googled a few OVPN settings the Inseego doesn't like and I've been monkeying around with those but no matter what I do, I can't get the config file(s) to be accepted.  I've sent a support request to them and am waiting to hear back.  While they post a support phone number, when you call it simply says to call your cellular ISP for assistance.  Nice!  I'm only guessing the amount of frustration I would be in for if I called my cellular provider to discuss an OpenVPN configuration back to my firewall...

Short of discussing all the details of what I have tried (somewhat blindly), I'm curious if anyone on the forum might have gotten an Inseego device to properly open an OpenVPN tunnel with an OpnSense router.  I've tried to minimize my configuration options as much as possible just to get a simple config file and connection up (cert elimination, etc), but no joy so far....

Anyone?
