ICS to two networks. How do you route between them ?

[Shawn]

Hi,

I am having a problem with my ICS.
It is setup at the moment with the 'ICS' machine (XP Pro) with three
NIC's
NIC#1 goes to cable modem (Picks up IP from Cable set top box.)
NIC#2 goes to LAN 192.168.0.1
NIC#3 is a pci wireless AP 10.0.0.1

All the clients on the ethernet lan (192.168.0.0) LAN pick up an IP
from DHCP and have internet and network access.

The AP is up and running and Wirless clients can connect, but NO
network access to the other network at all or internet at all.
Wireless clients dont pick up IP address.

Windows does add in a network bridge which i tried to configure, but
it made no difference at all.

How do I get the wireless network to talk to the Ethernet network and
share interner and File and Printing ?

Thanks gor any imput.

Excerpt from XP Help:
"You must enable ICS on the public connection of your home or small office
network. If you have more than one network adapter installed on your
computer, you need to choose the local area connection that communicates
with the rest of the computers on your home or small office network. This is
also called the private network connection. If there are two or more local
area connections, when you enable ICS, you must do one of the following:
Select one connection to connect to the rest of the computers on your
network. For information about how to choose the private connection, see
Public and private network connections.
If you have two or more local area connections, and all of them connect to
the rest of the computers on your network, you need to bridge the local area
connections before you can select the connection to your home or small
office network. If you choose to create a network bridge that includes all
of the local area connections to your network, the bridge is automatically
selected when you enable ICS. If you create a network bridge that does not
include all of the local area connections to your network, you can still
select the bridge as your private connection. For information about how to
enable ICS, see Enable Internet Connection Sharing on a network connection.
For information about how to bridge connections, see Bridge connections."

The wireless AP is in a different subnet than the LAN computers, which
will prevent the wireless and LAN computers from communicating with
each other. The wireless AP must use the same 192.168.0.x subnet as
the LAN. Here are two ways to do that:

1. Create a network bridge between NIC#2 and NIC#3, and use the
network bridge as the home network connection for ICS. Don't
configure the network bridge yourself -- let ICS do it.

or:

2. Disconnect the wireless AP from NIC#3 and connect it to the same
hub or switch that NIC#2 and the LAN computers connect to.
