Multihomed XP System and Routing Question

[Carl Muffoletto]

I have an XP box with two NICs each connected to separate networks, a
wireless and a wired. Clients on each network can reach clients on the
other, so the my dualhomed machine must be routing between the NICs. I would
like to disable this.

I checked the registry and IPEnabledRouter is set to 0 (zero)
(HKLM\System|CurrentControlSet\Services\Tcpip\Parameters). So I don't even
understand how the NICs are routing to separate clients on separate network
much less how to disable that function.

Can't find any useful info on the MS Knowledge Base. Anyone have an
explanation or suggestion?

Open the Network Connections folder and see if the network connections
for the two NICs are part of a network bridge. If they are, right
click and delete the network bridge to separate the networks.

Yes there is a bridge created by VMware. Of course that bridge didn't exist
until recently when I installed VMware workstation so I could run WinMe and
XP simultaneously. That's why I am just now seeing the clients on each
network connected to each other.

Thank you very much Steve for the advice.
