gateway_enable sets net.inet.ip.forwarding to 1, so that the host will
forward packets from one interface to another. That's what a gateway
nat is Numerical Address Translation. It's a function that a gateway
can do as well as forward packats, and makes it possible to hide
internal IP addresses and have multiple machines share an IP
address. Just having forwarding on won't do that.
