Fwd: [Gllug] ssh timeout

[Minty]

(bah, and to the list this time...)

I am indeed NATing outbound.  Just to add to the confusion, a ssh
connection I opened around 9pm tonight was still happily sitting there
4.5 hours later having been idle for at least 2 hours, which is plenty
longer than typical.

Any clues to the kernel value in question?  (I have googled, but this
ain't my hottest area).  Best guesses so far might be something
connected to
