How to set NIC to be default

[Guest Miha]

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

 

 

 

Regards,Miha

Think you're probably in the wrong Newsgroup for this one

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.

Re: How to set NIC to be default

 

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!
