Approach to use cross-over connect as part of LAN

[Guest]

Computers A & B each have XP Pro and are connected by a cross-over cable to
share printer.
Wireless nic was installed on A for access to existing 3-computer LAN
connected to cable modem through router.
How do I get B to access the Internet??
(Am volunteer for charity org, so my time is worth less than another
wireless nic for B)
1) It seems that ICS on A with B as client would set up dueling DHCPs and
NATs??
2) Can I set up static IPs on all computers and have A address router for
gateway and have B adddress A as gateway??
3) Can this be done at all??

Thanks for any help,

ICS should work fine as long as the "existing 3-computer LAN" is not using
192.168.0.x addresses. ICS will provide DHCP only on the crossover
connection.

And yes, instead of ICS you could simply enable routing on A, but you would
also have to configure a static route on the router. How you do this is
product dependent.

As Doug Sherman said, you can set up ICS on A with B as client.

An alternative is to create a network bridge on A, combining its wired
and wireless network connections into a single connection. B would
then connect to the same LAN that A connects to for Internet access.
I've written a web page with details:

XP ICS - Network Bridge

If the network bridge doesn't work correctly, try the steps shown

Thank you for your response. I was so encouraged with Doug Sherman's reply I
didn't think about details until the middle of the night.
As existing LAN uses 192.168.0.x addresses, I should avoid ICS.
Is your alternative as simple as this?
1. Make ad-hoc connection between A & B maybe even with APIPA addresses.
2. Connect A to LAN through wireless.
3. Bridge between wireless & ethernet on A.

If the existing LAN has a DHCP server, you can probably configure DHCP
to use a subnet other than 192.168.0.x, thus allowing ICS.

Yes. You've already done #1 and #2. All that's left to do is #3.
