Multiple gateway on single nic question

Hi,

I've got a query about using a number of IP addresses across 2 subnets which
are assigned to one NIC.

My question is, is there a way for Windows to force all IPs on a certain
subnet to go to the assigned default gateway and the same with the other? as
at the moment I'm receiving a number of alerts on my firewall which shows
that the IPs are sometimes trying to send data on the first default gateway
in the list, then trying the second one - the correct one.

For example I have the following example config:

10.1.0.0 subnet
10.2.0.0 subnet

It appears that sometimes the 10.1.0.0 subnet IPs sometimes try to go over
the 10.2.0.0 gateway and vice versa.

There's nothing wrong with the data transmission as its all working, I'm
just trying to cut down on network traffic and the amount of alerts I'm
receiving in my logs regarding this.

I'm using Windows 2003 Standard SP2, if anyone can give suggestions that
would be great.

Hello Marcus,

Your posting is not really clear. If you have to subnets you have to connect
them with a router. In every subnet you have a default gateway ip address
and the router knows the way to the other subnet.

Like Meinolf I am a bit mystified by your post. Why do you have two IPs in
different subnets on one NIC? Is it just on a server or on all the machines?
Since they all go out the same firewall, what is the point?
