Description:
i have rb750gr3 and 3 usb lte modem setup for mobile broadband load-balance. they’re all huawei e3372. they were flashed with serial mode (ppp) firmware. so, i can get they wan ip easily.
in mikrotik compatible lte usb modem list, i see that e3372 have the capability to ip passthrough in lte mode. now, i’ve flashed them with its original firmware (hilink mode).
My question is:
how can i get all 3 wan ip from those 3 usb lte modem? and should i sacrifice mikrotiks lan ports?
When you use HiLink then you must receive IPv4 address from E3372 who give you Private IP, not Public IP and you see it as lteX interface.
You can setup DMZ and it stop’s here.
This way consume less USB Endpoint’s and you can use more E3372 via USB Hub.
E3372 is always detected with minimum feature in my case and I never have got possibility to use passthrough mode on it.
When you use a modem mode, means PPP then MikroTik receive a Public IP.
USB Endpoint probably can work with only one modem. In some number of E3372 will stop detect new Port usb* but it detect it in usb bus. Like 10x E3372 but only usb1 will be detected.
a guy from official mikrotiks support, (about this issue) told me to hire a certified mikrotiks consultant. then, i might assume, it would be possible to do…
You should have left the modems in PPP mode, that way you have more control over IPs and connection overall. Hilink sucks, you have to use modem web interface to set things and never have direct public IP, modem always does NAT.
if necessary, can get access to this hilink mode as root, with telnet.
i was have an idea, if getting wan ip with mikrotik is impossible, why not create bridge “inside” the modem itself. i have root access to the modem with telnet.
what i don’t have, is guidance how to make bridge “inside” the modem (i’m guessing the os is android).
btw, is my comment approriate in this forum?
I write additional info.
E3372 in hilink mode get Wan IP from ISP to himself and this “router&modem” not have build-in feature to give/move his WAN IP to next device.
E3372 have got the LAN IP (192.168.8.1) and this IP gave-got own dhcp-server and first device who will be his dhcp-client reach 192.168.8.100 .
You can use DMZ into 192.168.8.100 if you use custom/modded firmware and have got additinal settings like change/select Band’s etc.
Now, the MikroTik LTE PASSTHROUGH for E3372 in HiLink mode works as assign this E3372 LAN IP into other MikroTIk interface like Ether4. This move LAN IP onto MikroTik interface.
This is describe here. Mikrotik and Huawei 3372 LTE modem - LTE Passtrough
Only when E3372 is setup as PPP mode then MikroTik can reach E3372 WAN IP at lte1 interface.
I hope this is clear now. This mode use more USB Endpoint’s, means smaller nubmer of device can be used by USB HUB.
You can write a post at forum where create a modded firmware for e3372 - if you use that firmware then you should know the source of all this.
thank you my brother, you’ve saved me from wasting my time…
btw, i wonder, how many identical usb lte modem can actually fit to rb750gr3 with usb hub?
i wonder, why that support guy told me to hire mikrotiks consultant?

ROS have got 32 endpoint to assign.
You can plug e3372 in modem or router(Hi.Link) mode to any linux and check it via lsusb -v command and compare that.
PPP use more usb endpoint’s.
If you check this then please write me. I know that many firmware mod’s use different features like with adb or without it = differ usb endpoint used.
in ppp mode, rb750gr3, can handle 2x e3372 only. while, i attach 3x e3372 to the usb hub. 2 modems are active as ppp, but 1, with red text and not shown in interface.
How did you flash it? I’ve tried many times connecting that pin to ground but it doesn’t appear for flashing.
there are 2 ways to flash it… using pin and balong, or balong and AT command.
