TCP keepalives get sent so rarely that they don't keep NATed connections alive. (Linux's tcp(7) says the first one is sent after 2h of idling)
Its the same for windows systems, 2 hours. All routers SHOULD keep the NAT connections open for at least that long.But its not always the case, a few years ago I had to get a FIX for an Alcatel Speedtouch Pro since its was originally programed to drop TCP connections after 15 minutes.
