Multiple Networks On XP Computer

[Guest]

I have a client with two XP Home machines. He has DSL connected to one, and
shares that through an ethernet connection to the other computer. He has File
Sharing disabled on that connection, for security reasons. He wants to add
yet another physical network between the two computers for an internal LAN.
This one would allow File Sharing between the computers, yet be separate from
the Internet connection. I have put in another NIC and run a crossover cable
between the computers. I have not been able to get them to talk on this
connection. Is this going about it the hard way, or how do I set this up for
this internal LAN?

If I understand correctly, the host machine has two network
connections: a shared DSL connection, and an Ethernet connection to
the client computer.

If so, there's no need for another NIC in either computer or for a
second network between them. It's OK to enable File Sharing on the
existing Ethernet connection, because it uses private IP addresses
that are inaccessible to other Internet users. In particular, XP's
Internet Connection Sharing assigns a private 192.168.0.x address to
each computer's Ethernet connection.

Only the host's shared DSL connection is exposed to the Internet.
That connection needs firewall protection, such as XP's Internet
Connection Firewall (RTM and SP1 versions) or Windows Firewall (SP2
version).

Get a Router/Firewall that has four port and connect the PC directly to
the router and the router connect directly to the DSL modem. This way
you do not need to use ICS to share the broadband connection. With this
set up you do not need to leave the one PC on all the time to be able to
have access to the internet from the second PC. Since the route is also
a firewall you do not need to use XP's Internet Connection Firewall. You
only need one NIC card in each PC.


The configuration information may not be the same for you setup, just
depends on who you ISP is, but take a look at the following setup to see
what I am referring to.
