This is a via a local LAN but yes that would be a possibility when
masquerading. [Thinking about this, though, if the routing tables on
the particular machine which I'm logging in *from* are not set up
correctly, it *might* be using the default gateway for it's
connections. Just checked - auth.log is giving that machine's correct
name.]

Most likely but I checked syslog; I figured that there might be
mention of it "User has been idle 2 hours. Disconnected." but there
was no mention of it.
Another person wrote back and simply stated "debian-user"; I thought
this might be a daemon or cron job that is periodically called which
disconnects idle users but I have not been able to find it.
Oh well. Thanks.
