That is slightly incorrect. It can forward unknown packets just fine, if
you ask for the right type of NAT. Don't think the restricted cone NAT you
get when you do many-to-one "Linux SNAT" is all there is to NAT.
In fact, you can do _stateless_ 1:1 NAT just fine in Linux with a recent
enough kernel and userspace, which by definition only deals with unknown
packets since it doesn't do any connection tracking (or it wouldn't be
stateless in the first place).
