Nat translation limits might not only be related to his first hop nat device
In the home, but these days with the exhaustion of ipv4, the second hop
carrier grade nat (cgnat) device in his upstream provider could be limiting
also.
I run a cgnat for an isp and allow 2500 ports per customer private address,
and time out those translations at 120 seconds. It's possible to hit a
limit there. I see it sometimes.
