Tried another PC.
I see openwrt 192.168.8.123
Modem 192.168.8.1 no.
So what network is:
172.16.0.0/24???
check the 1st post, it's there.
Correct.
Yes, the OP states this...and then proceeds to show devices and configs that don't contain 172.16.0.0/24.
But has some device issuing the addresses via DHCP...?

- Your OpenWrt config does not show this
- If OpenWrt is the router for 172.16.0.0/24, you don't need a static route; but, you may have to allow forwarding to WAN if you created another firewall zone
This should work on a default OpenWrt by making the LAN 172.16.0.0/24 and connecting WiFi as WWAN.
Does your cell carrier allow connecting hotspots to routers?
How to fix configs?
Yes, you can connect.
To be clear, what needs to be fixed doesn't seem to be in your config (which means there may be another router).
But to do this with the OpenWrt, you:
- Reset router to default
- Unplug/plug all Ethernet devices (your OpenWrt will be 192.168.1.1)
- (OPTIONAL) change to 172.16.0.1/255.255.255.0 if desired
- Unplug/plug all Ethernet devices (your OpenWrt will be 172.16.0.1)
- Go to Wireless, connect to hotspot as WWAN
- follow defaults to place in WAN firewall zone
- Done
Please use the LAN ports on the OpenWrt to setup, this will ensure there's no other network device issuing 172.16.0.0/24 to your machine connected by Ethernet...I'm not sure you understood that your OpenWrt config doesn't have such a network listed.
Does the wireless link from OpenWrt to the modem work? From OpenWrt are you able to ping the modem?

How to properly set up a firewall?
If you did this, it's already setup as WAN and LAN.
- LAN does not need DNS

After resetting the firewall settings file, there is no.
(default reset is firstboot && reboot )
I mentioned nothing about firewall except adding WWAN (see below) and you said you did not edit the file. There is a WAN and LAN by default, and WWAN is automatically added if you followed my steps above.
If you used command line, add WWAN network to the WAN firewall zone in /etc/config/firewall.
I don't have a web interface.
I don't have a /etc/config/firewall file.
Create a firewall file with such data?
config defaults
option syn_flood '1'
option input 'ACCEPT'
option output 'ACCEPT'
option forward 'REJECT'
config zone
option name 'lan'
list network 'lan'
option input 'ACCEPT'
option output 'ACCEPT'
option forward 'ACCEPT'
config zone
option name 'wan'
option input 'REJECT'
option output 'ACCEPT'
option forward 'REJECT'
option masq '1'
option mtu_fix '1'
option network 'wan wan6 wwan'
config forwarding
option src 'lan'
option dest 'wan'

What is CyberWrt!?!?
(The website is in Russian...and mentions EOL version 15.)
Please use official OpenWrt.

You're making a routed client. There are instructions in the wiki for that.
The default network and firewall is set up to NAT route to a wired WAN. The simplest way to set this up is remove the Ethernet port from the existing wan network and use a wifi client instead. This is all that needs to be done if the upstream network doesn't overlap the default lan IP range. If it does, you need to change the LAN IP for proper routing to work.
Another way is to make a new network with the client, which is usually called "wwan" (though you can name it anything you want subject to network naming restrictions), and add this network to the wan firewall zone. The "Join this Network" button on the wifi scan page is a script that does that. It usually works, especially if you click it only once starting from a default configuration.
Once you have Internet access working you can look at finer points like giving wan a static IP and opening firewall ports so you can log in from the WAN side. That only makes sense if you control and trust that network.
