Hi @yipingwang
Flashed all firmware generated by core-image-minimal from yocto and borad bootup good.
[Internet] ----- RGMII1(eth0) --*-- LS1046ARDB --*---(eth2)SGMII1 ----- LAN network
WAN eth0 got IP from my router as DHCP client.
on LAN eth2 i am running DHCP server so client on behind eth2 is getting IP address ,
but i am not able to ping from eth2 to eth1 or clients on eth2 cannot access internet,
so we need install any kernel or user level package to get networking stack working in this case?
NOTE: enable forwarding and disabled all iptables but same issue
thanks please help in this urgent case
