> hash:net,net

daddr and 255.255.255.0 vmap { 10.10.10.0 . 10.10.20.0 : accept }

> hash:net,port,net

% nft add rule tablename chainname ip saddr and 255.255.255.0 . tcp
dport . ip daddr and 255.255.255.0 vmap { 10.10.10.0 . 80 . 10.10.20.0
: accept }

% nft add rule tablename chainname ip saddr and 255.255.255.0 . iif
vmap { 10.10.10.0 . eth0 : accept }
