<i>Assuming you have an actual modem, as well as this AT&T
"Gateway" device...</i><br>
<br>
I would personally use my linux machine as the "router", connected
directly to my modem (via eth0), and then connect the AT&T
gateway appliance (either directly, or through a dumb ethernet
switch that is connected) to my 2nd NIC (eth1), and use IP
Masquerading (iptables / ip_forward /etc.), to secure/isolate and
easily monitor the traffic on my network. This would of course
involve various DHCP and Static IP routing, but gives you much
better control, and the confidence that you can actually see what is
going on within your network, than most embedded router/firewalls,
imo.<br>
<br>
You can then use any number of the hundreds of network analysis
tools provided in common distros. (wireshark, sslstrip, etc.). Of
course, you'll spend hours and hours locking-down the 'router' w/
custom iptables firewall rules, but that's a good exercise to learn,
imo.<br>
<br>
I'm sure most would suggest using OpenWRT on a 3rd party embedded
device, but that's no fun. =p<br>

connected to an AT&T Gateway, other items such as an Apple TV,

1 of our quite knowlegible Luggers suggested I run mrtg to

through this router, however, since I am still totally blind, an
output would be

completely graphical. So I phoned the Leo Laport show on Saturday.
As comments
<br>
came in, an interesting suggestion. Some1 is betting a conflict
among my desktop
<br>
machine and the Gateway? So if this is the case, can some1 please
inform, can I
<br>
manually change an ip address of the local Debian machine? And
exactly what will
<br>
I type?
<br>
When the desktop is even disconnected from the Gateway, even
3minutes, the 2nd
<br>
Uverse box wakes up, but since I watch CNN International `alot, I
really `need
<br>
to find a solution. Several Uverse techs were sure it is the
desktop machine, no
<br>
matter what other items are wireless or ethernet, they will not
connect while
<br>
desktop is connected. Thanks so much in advance for suggestions.
This machine is
<br>
still running at 157 days.
