iptables: No chain/target/match by that name

[Christopher Bianchi]

hello ! i'm trying to configure nat portforwarding for my virtualbox,
not with VBoxManage but with iptables, but the problem is this:

ienabellamy at charlotte:~/Bin$ sudo iptables -A PREROUTING -p tcp -m tcp
--dport 80 -j REDIRECT --to-ports 8080

iptables: No chain/target/match by that name

The error means that i'm missing some module ?

thanks for the help !
