What does their fix look like? I guess you can't change this limit for all connections otherwise they'd have to buy more IP addresses for their NAT routers, so maybe they only fix it for SSH connections, them being few?

I had the same problem and did the ~/.ssh/config trick years ago. Interested in contacting my ISP so that they fix the problem for all users (although it might be fixed now, idk).

They will increase their "TCP established connection idle-timeout" from 1 hour to 2 hours and 4 minutes as I requested.

This shouldn't make much difference for them. Most connections are closed within a few seconds anyways. Long lived connections with no traffic are rare.

With no data whatsoever, I'm guessing less that 1% increase in NAT table size.
