This tutorial is meant to show how to use nftables to build a router suitable for a home or boat.
Setup
Make sure that ip_forward is enabled in the kernel.
cat /proc/sys/net/ipv4/ip_forward
0
This shows that it's disabled. To enable it, write "1" to that virtual file
echo 1 > /proc/sys/net/ipv4/ip_forward
cat /proc/sys/net/ipv4/ip_forward
1
