Changing default IP address when running server on two subnets?

[Fox1977]

Hi there,

I have a windows 2003 server with two network cards in running on two seperate subnets. These are running behind a firewall that (at present) doesnt route between the subnets.

I have had to add the second card to the server in order to add the additional subnet as we needed to use more IP addresses. This server is in a data centre running a number of websites for our company.

The server is running with the two subnets and by default all of the outgoing requests are going out on the new subnet. This is a bit of an issue as the server is part of a bigger network and there are a lot of routing rules in place. How do i get the requests to come from the server with the source IP address as the first subnet that was running on there?

I have gone into the network connections > advanced > advanced settings and changed the order of the network cards so it uses the first network card/subnet but it still hasnt applied the changes. Why i go to an IP lookup website it still lists the new subnet as the source.

Any ideas? Does the server need a reboot for the changes to apply?
