About nft forward

Hello, all
I meet forward problem when use openwrt with 1wan 1lan, the device behind lan cannot connect to device out of wan, look at nft tables, it seems forward is good, I'm not good at nft, can somebody help me.
I have two net device in my device, eth0 use as lan, and eth1 use as wan
