Hey Benny!

 BP> not working eksample that works in pratice

Yes it is.  In fact it is NATing for 3 smartphones for about a week now and
have yet to hear a complaint from any of them.

----- /etc/sysconfig/ipv4-masq starts
table ip nat {
  chain prerouting {
    type nat hook prerouting priority 0; policy accept;
  }
  chain postrouting {
    type nat hook postrouting priority 100; policy accept;
    oifname "eth0" masquerade
  }
}
----- /etc/sysconfig/ipv4-masq ends

I start it up in the wireless rc script using these two commands;
  echo 1 > /proc/sys/net/ipv4/ip_forward
  nft -f /etc/sysconfig/ipv4-masq

It's just that simple.  Mind you the iptables NAT/masquerade wasn't anymore
complicated.

Life is good,
Maurice
