OpenWRT on DIR-320NRU: how to distribute Internet from a 3G modem to a local network?

Question

network hardware

Successfully installed OpenWRT on DIR-320NRU, Huawei E173 modem was also launched. Now the Internet works when connected via WiFi, but does not work via LAN. I don't have much experience, please help. There is a web-interface and an ssh-console, with the commands of which I am practically not familiar.

Answer 1

Place interfaces in the same zone in the firewall.
