I have two Win 7 PCs and two Win XP PCs, all Pro versions and several

Would it be beneficial and or doable to have only one PC, call it the
master, connected directly to the internet through the ATTUVerse modem?
What are the pros and cons?

If so, can someone explain or point me to a how to for one point
internet access.

My definition of one point internet would be to have the LAN
disconnected from the internet but PCs have access to the internet
through the master PC therefore I can monitor all traffic to the
internet on the master PC.

Would I need additional hardware beyond the two switches and secondary
router that I already have? Just reroute differently.

One limitation of ICS under Windows, is the LAN segment on the right
of that picture (labeled "ICS"), is fixed at 192.168.0.x subnet. It's possible
if you set up the PC_with_two_NICs under Linux, you might
have more choices on the subnet. This is only an issue,
if you're trying to avoid "upsetting" the existing setups.

I have set up ICS in the past, but don't remember anything
of the experience. Maybe someone else can give a rundown on
the operational characteristics.

When you string a bunch of routers like that, sometimes you manage
to "partition" or isolate the file sharing on one PC from the other PCs.
If the PC_with_two_NICs is not doing file sharing, then chances
are the above diagram will work OK.
