hello, i have a BPI-R3 borad. When i use img(open wrt 21.02) from this forum。the routing is deal with HW.but the NAT/PAT is not work .i want chage the PORT/src IP through UI.but it can not work. and the hnat info like bellow. image

then i move to open wrt 23.05.5 and 25.12.3 come from openWRT offical website. the same operation as before. the routing is not deal with PPE but CPU,and NAT/PAT not work too! the PPE info like bellow

root@OpenWrt:~# cat /sys/kernel/debug/ppe0/entries | grep “112” 01bd8 UNB IPv4 5T orig=192.168.1.20:32330->192.169.12.112:2321 new=0.0.0.0:0->0.0.0.0:0 eth=00:00:00:00:00:00->00:00:00:00:00:00 etype=0000 vlan=0,0 ib1=1001e11d ib2=00000000 packets=0 bytes=0 all the entry is UNB. so how can i make the fastpath work with routing,NAT/PAT and so on?
