I want to share my internet of eth0 to the wlan0. So I followed this tutorial:
https://wiki.archlinux.org/index.php/Internet_sharing
my Kernel version is 4.1.15
The modules I already have loaded are:
nft_chain_nat_ipv4, nft_nat, nft_masq, nf_tables_ipv4
I set /proc/sys/net/ipv4/ip_forward as 1 as well.
Then:
nft add table ip nat
nft add chain ip nat prerouting type nat hook prerouting priority 0 ;
nft add chain ip nat postrouting type nat hook postrouting priority 100 ;
worked fine. nft list table nat also shows the NAT table.
Then:
nft add rule nat postrouting oifname eth0 masquerade
shows
<cmdline>:1:1-49 Error: could not process rule: No such file or directory
It seems I have to load another module? Or what did I do wrong?
update: I solved the problem myself. It seems the modprobe is very intelligent and every dependencies should be loaded automatically.
My problem was: the folder name of the module under /lib/modules is xxx-yyy. But my the uname -r on my pc shows xxx. So I changed the name of the folder from xxx-yyy to xxx. Everything works fine now.

It is probably easier doing bridging.

@RuiFRibeiro Hi. I already successfully did it with bridging. But just want to know how to do it with NAT

Why NAT? Do routing between internal networks.

@RuiFRibeiro Cause I want a static address for the wlan0, which can only be done with NAT. If I bridge them, I cannot visit the device with a static ip.

make sure that theiptable_natmodule is unloaded, and what will happen if you remove theoifname eth0section from the command.
