Re: Two NICS - Windows XP - I don't want any traffic between them

OK, I'm not familiar at all with this kind of device. Unless this is a VoIP
network or the phone box dials up the Internet, I don't see that it needs a
default gateway or other routing configuration. However, if it is trying to
route packets to the Internet through your XP machine, you would want to
enable routing on the XP machine. Also, you might need to configure a
static route on the LAN router so that it knows where the where to send
packets destined for the NIC connected to the phone box. Try:

1. Open Network Connections. If a bridge has been configured, delete it.

2. Remove the default gateway from the configuration for the NIC connected
to the phone box.

3. Move the LAN NIC to the top of binding order.

4. Enable routing on the XP machine.

5. Make sure that the phone box NIC and your LAN are on different subnets.

6. On the LAN router configure a static route to the phone box subnet which
points to the IP address of the LAN NIC.
