Mikrotik RB with huwaie router WIFI

We have a strange issue

We using the huwaei b315 LTE eg, 192.168.8.1,

We disable DHCP on huwaie, and only keep the WIFI active

Plug mikrotik into port 1 of huwaie

ether1 : 192.168.8.2
ether1: 192.168.0.1

enable dhcp for 192.168.0.0/24 on ether1 on mikrotik

Clients connect to WIFI on huwaie dont get dhcp IP, however we can set static ip addresses and it works

I assume the hauwie has some sort of firewall switch security, we have tried every possible setting on hueawie.

Is there anyway around this or some advice would be appreciated

You need to understand in which interfaces of Huawei router works DHCP server.
