Okay, so exactly how many times do you think we have to say in this thread
that by "NAT/PAT", we mean NAT/PAT as typically implemented in the very
cheapest routers in their default configuration?


Even the cheapest routers have a 'DMZ' configuration option that adds
a rule that, by default, sends all the traffic to a particular host.
And using that is a fairly common solution to bypassing problems with
port forwarding and NAT.
