Hi there,
I have a 4G/LTE usb dongle, a Huawei E3372s-153, that has been absolutely driving me up the wall that I want to use as a failover device for a pfSense VM I am running within my Proxmox host. I've had less than no luck passing it directly to the VM, but after HOURS of trying various different ways of connecting it and mode switching, I've finally managed to get it so that it is at least connected and working as an MBIM device on the Proxmox host itself.
What I would like to do is somehow create a bridge that I can assign to the pfSense VM so that it can assign it as an interface and use it as part of a failover grouping. I understand how to create bridges and associated them with interfaces but unfortunately, I think due to the dodgy way the device "fakes" being an ethernet device, as soon as you attach it to a bridge, both it and the bridge stop working and the device isn't capable of a true/traditional linux bridge.
I've tried to follow countless articles on various ways of routing data to this device in a way that I could then expose to the VM but due to my basic knowledge of networking, I haven't managed to get any to succeed. Most articles I have followed have been concerning bridging WLAN rather than an MBIM sourced connection to another physical interface and I think this is where I am falling over. I essentially need a bridge that somehow auto routes any traffic to it through the MBIM interface. Hopefully that makes sense! I would be beyond grateful for any help as I have no wasted 10s of hours trying to get this thing to work and am starting to go slightly insane!
Here is my current interfaces setup:
Here is the ifconfig for the MBIM:
And here it is allowing me to successfully grab the public ip:
Even the simplest, worst advised thing that could make this work would be amazing, it's just a hobby box really!
Thanks so much!
