Add 2 LTE Modem to Routerboard

i have 2 E3372 huawei LTE modem and connect them to RB951 with usb hub.
after add DHCP Client Mikrotik get IP 192.168.8.100 / Getway 192.168.8.1
i can’t change E3372 IP Range or Getway IP Becuase have not DHCP Configuration in modem.

How can i use 2 LTE together and fix this problem when 2 getway have same address?

It is a Huawei issue, report it to them…
Also ask them to offer a transparent (no NAT) mode when you are at it.

change WebUI to ver 17
in that version u can change ip range in dhcp server

Where can I download this version?
