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

Thanks for all the tips -

3 how do I move it to the top of the binding order?

4 Tips on the routing would be helpful too.

6 - ? I have a network card connected to an unmanaged switch that the
network card plugs into which goes to a firewall which goes to a router
which goes to the internet - not sure if you are referring to anything along
this line
