My laptop is happily displaying on my monitor (through a KVM) here at
the office. Perhaps there is a GPS device that disables the external
video port when I am more than 10 miles from the office. Hopefully, I
will find a better explanation.
Much thanks to Bill Sconce for being there to set up a VNC connection
and allowing me to drive from his laptop.
Let me provide some URLs in a clickable form for any folks who are
interested:
http://iptables-tutorial.frozentux.net/iptables-tutorial.html
iptables is the IP packet processor that provides a stateful firewall in
Linux.
This page covers much more than just iptables. It provides detailed IP
protocol explanations.

Short example of using bridging and ebtables to control traffic on the
ethernet frame level. Another case of controlling local packets without
regard to the IP addressing.

Documentation part of the openwrt web site.

Contains the block diagrams to show internal operations.
In pushing things around just now, the external monitor went blank.
It's a hardware problem! My cable here is pretty stiff so it normally
provides some upward pressure on the external video connector. With no
pressure, the screen goes blank.
