Installing and Using OpenWrt Network and Wireless Configuration

hi to everybody. I'm trying to use OpenWRT on a custom board. LTE works fine, but computers connected via cable (ethernet) don't have internet. I've pinged 8 8 8 8 and downloaded via wget on OpenWRT device. here is the output of ifconfig command:

which DNS IPs are shared with the clients through DHCP ?

The wan network is named "wwan0", but in the firewall you have "wwan".
