Not sure why are arguing with the author.
He didn't say that we were allocating a port for every internal port.
There have been extensive discussions on the jool list about how to make it
work better with netfilter, but there are challenges since netfilter is
currently IPv4 only or IPv6 only with different tables. And locks and RCUs
to deal with.

But, they aren't all available, because we can't share a port with NAT44.
