In openwrt, configure following:

/images/2021_06_07_07_36_24_553x374.jpg

Then in nuc(192.168.1.222) add following items:

# sudo route add -net 192.168.0.17 netmask 255.255.255.255 gw 192.168.1.2 enp3s0
# sudo route add -net 192.168.0.0 netmask 255.255.255.0 gw 192.168.1.2 enp3s0

While 192.168.1.2 is the openWRT’s wan address, while the 192.168.0.0/24 is its lan address range.

From now we could directly get to the 192.168.0.1/24 range.
