I have two home PCs (WinXP and WinME) sharing a broadband internet
connection via a NAT router. I wan to make each machine completely invisible
to the other. The thinking behind this is, if one machine gets a worm/trojan
etc. the other machine will not get infected because there will be no TCP/IP
communication between them even though they share the same router.

Is there a way to do this without wrestling with IPSec/local security policy
or installing a personal firewall on each machine? I do not want the users
making decisions on what to block/allow etc..

Basically my network will be:

Router 192.168.0.1

Computer_01 192.168.0.2

Computer_02 192.168.0.3

(the IP address above are not set in stone, they're just to illustrate a
possible config)

I just want to set it up so Computer_01 has no possible way of receiving a
single packet from Computer_02 and vice versa, but they both must access the
web.

What is the "easiest" way of doing this?

Thanks,

Paul
