Required? Technically, no (although it's a good idea for many
reasons in most situations).
..
Quoting from <http://lists.openwall.net/netdev/2007/09/27/55>
" Stateless NAT is useful in controlled environments where
restrictions are placed on through traffic such that we don't
need connection tracking to correctly NAT protocol-specific
data.
What restrictions would those be? The only one I can think of is
when the NATting is 1-to-1 with respect to internal and external IPs.
