Config error.

iptables-nft and fntables are not the same.
-j CT works with 'connection tracking templates',
but the nft equivalent sets the helper directly.

So, for iptables (and iptables-nft), the rule needs to be
executed before conntrack lookup.  With nft it has to be done
after conntrack lookup.
