How to set NIC to be default

Hi



Have a problem with setting one of two Ethernet adapters to default.

Win2003 Web Server, 2 NICs are connected to a switch which has two firewalls
connected to it.



1 NIC 190.191.0.18/16 GW 190.191.2.1

2 NIC 190.191.0.17/16 GW 190.191.0.1



First NIC routes through a firewall that has access to the internet, second
NIC routers through a firewall that has access to LAN and Internet.

But after restarting server, or disabling/enabling second NIC, default
traffic is always routed through second NIC through GW 190.191.0.1, but I
want that internet traffic is always routed through the first NIC that has
GW 190.191.2.1?

So in other words I want to achieve that first NIC will be default adapter.

How can this be done?

Thank you in advance

You should not have two NICs enabled which are in the same IP subnet,
unless they are teamed. You can only have one gateway per machine, not one
per interface.

What is the purpose for this unsupported configuration? It doesn't make much
sense. And why are you using a class B network mask?

If you want it to work you need to create a routing table on your server and
tell it which addresses to use with which interface. In order to do that you
first need to define the traffic that you want to see over the 0.17
interface. What is the subnet range that you want to use via 0.17? After you
have done that, you send the rest through 0.18.

Yes that was the problem. I deleted gw on the second nic and now it works
like we wanted.
Thanks!
