Anyone use or have tips on using a MiFi device as WAN source? I just bought an Inseego MiFi Pro M4 to use with my lab and for use in the car on trips. It says it has USB tethering, but also has rj45. It's T-Mobile so probably behind CGNAT, but that's the world I live in now, Netbird can get me around that for remote work. Everything I do now is behind multiple NAT of one form or another, yes it is less than desirable, just have to work with what you can get.
The hardware does support static IP, so I might look into that later and pay for an IP if T-Mobile can offer that (then run a local Netbird or other server).
Why did I go with that specific device? It was the only in stock 5g device that they offered that also has external antenna connectors (2 of them). External antenna can be a make or break feature depending on your location.
Any tips to get this working with OPNsense would be appreciated, lots of open USB ports if tethering is the best way forward. Link to the product https://inseego.com/products/mobile-hotspot-routers/mifi-pro-m4/

Invisagig (https://invisagig.com/)? Can't comment on stock, and the Inseego appears to be considerably cheaper.
I'd think the Ethernet would be the way to go from a connectivity standpoint, but only if the device can bridge, like most 802.11 devices. That's always been a question for me, and I'm not curious enough to purchase a service to answer it. Particularly since I need multiple static IPs, and I haven't seen such an offering from any (somewhat reputable) U.S. carrier.
