Usb eth0 adapter gets no ip from OpenWrt

Hi,
i'm not sure if this really a OpenWrt problem or not, my problem is that my lan to usb-c not get an ip from my OpenWrt router.

My network topologie:
modem/router(subnet 192.168.0.1) lan---> OpenWrt (subnet 192.168.1.1)

I also have 2 DHCP Server on every router once, actually behavior of my lan adapter it get's an ip like 192.168.0.X, then i've looked in my OpenWrt CLI with arp -a and didn't find my adapters mac address, but if i go to switch in luci i see the port is plugged in, then i went to my modem/routers webui and see there is my adapter (I don't know if is important it was shown on the same lan port as my OpenWrt lan port), now i have tested to disable dhcp on my modem/router, and now my adapter is fully useless, i attached the dhclient log:

The same behavior if got on Windows, Arch and on another Computer.
I have also tried to restart my OpenWrt, and add an ip with mac manually to the arp table.

OpenWrt Version 19.07.03 Archer c7 v5
My lan to usb-c: digitus dn-3024

Can anyone help me to resolve this problem?

opkg update
opkg install tcpdump
tcpdump -vni any udp port 67

thanks for the reply, here the output of tcpdump:

sadly it change nothing.

uci set dhcp.lan.force="1"
uci commit dhcp
/etc/init.d/dnsmasq restart

I've also rebooted.

It looks like you have other DHCP clients.
Can they obtain an address?

yes my laptop got over wlan a dhcp address and also my pc over lan.

You can try to capture the detailed DHCP message:

I suspect the problem is the missing DHCP option 61 aka Client-ID.
Check some other up-to-date Linux live disk like Fedora or Ubuntu.

I have it in any OS, with this adapter

You've reconfigured the switch so that ports 1, 4, and 5 are hardware switched at the WAN side eth0.2. Are you plugging Kali into one of those ports?

Since OpenWrt's WAN is still a DHCP client (the default configuration), eth0.2 is not going to answer DHCP requests. These requests should be answered by the main router plugged into one of the other ports. But if you're for example bridging directly into a cable ISP they only give you one IP.

Sorry for the circumstances, but thanks for the help @vgaetera, yes you're right i've configured lan port 3 as WAN and that was my problem, but i forgotten that i've done it, a lot of thanks @mk24.
