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



We need more information about what you are trying to do. It sounds like
you have two routers, and one of them is described as being on the LAN, the
other is not. If these are both merely Internet routers, then you do not
need 2 default gateways; or you can configure 2 default gateways and give
one a lower metric so that it becaomes the 'default' default gateway. Does
one or both of these routers provide a gateway to some other network? If
so, you can use a static route to the other network pointing to the correct
router, and you do not need to set that router as your default gateway
unless it is your only connection to the Internet.
