Hello there!
I have a usb dongle (modem) for 4G LTE connection, but can't access its web-gui via 192.168.0.1 and (another one) 192.168.1.4
What firewall config do I need to have access to web-gui?
are you sure the UI is accessible once the connection is up ?

First make sure you have no IP address conflict between LAN and WAN subnets.
Can you ping 192.168.0.1 from OpenWrt console?
If yes, install curl then execute curl -I http://192.168.0.1 and show result.
What is your modem model?

No, I cannot ping modem.
root@OpenWrt:~# ping 192.168.0.1
PING 192.168.0.1 (192.168.0.1): 56 data bytes
^C
--- 192.168.0.1 ping statistics ---

Modem models are:
ZTE mf833n 192.168.0.1
Huawei E3372h 192.168.1.4
Neither is working tho =
on a side note i've tried usbmodeset with no avail.
Yes, It's working from my PC.
There was some firewall rule that provided web-gui, but I've lost it due to bricking and debricking my router.
Let's focus on ZTE for now.

I've tried setting up modem from wiki with no luck. Although I didn't tried sending manually AT commands due to the fact that there is no serial USB device in my system.
Also I've found snippet from wiki in traffic rules that works
config rule
option name 'Allow-ZTE'
option src 'lan'
option proto 'tcp'
option target 'ACCEPT'
option family 'ipv4'
option dest 'wan'
list dest_ip '192.168.0.1'
