since the netfilter/iptables NAT implementation is fully dynamic
stateful NAT, you cannot use any of our nat features without connection
tracking.

It is also not possible to do NAT in a safe way, if connection tracking
applies only to certain packets.  Because unless we lookup a connection
tracking entry, we don't know which NAT bindings to apply to the
particular packet.
