Huawei E3372 USB LTE modem in HiLink mode
Are there any plans to fully support Huawei E3372 USB LTE modem in HiLink mode, including its LTE connection management?
It seems original E3372 modems (firmware 21.x and below) presented themselves to the host as USB serial (COM) devices, over which the host (PC or Firebox) would run PPP or NCM connection to the ISP.
However, current generation of E3372 sticks come with "HiLink" firmware 22.x, which instead presents the modem to the host as a USB network (RNDIS) device, with modem itself acting as a mini-gateway - it has built-in DHCP and HTTP servers, gives out IP4 address to the host in 192.168.8.0/24 range with 192.168.8.1 default GW, performs NAT, and can be managed via its web interface.
I was pleasantly surprised that my Firebox (firmware 12.2.1) recognized the modem, obtained IP4, and let me set it up as another external interface with fail-over from our main ISP - multi-wan, link monitor, SD-WAN (well, PBR for me), etc.
The kicker is that actual LTE connection state is now managed exclusively through modem's web interface - as opposed to "dialing" PPP/NCM connection with original "serial" modems - and Firebox has no clue how to do it. I can manually open modem's web UI in a browser from a LAN PC and toggle (connect/disconnect) it, but I'd prefer Firebox to manage it automatically to keep LTE data usage to a minimum ($$$).
Any plans on adding connection management to Fireware? It would amount to issuing (via curl) specific HTTP requests to modem's default GW address. I can supply HTTP traces of relevant actions if needed.
