Routing between subnets

  1. Based on your post I would add a second NIC in the mail server on the 192.0.3.x network.

  2. If you’re using a general purpose router (Cisco, for example) you can add another interface for your router on the 192.0.3.x network. It will work seamlessly to the 192.168.0.x clients, assuming that router is the default gateway or sych’d up with your other routers via a routing protocol.

[quote=“sureideas”]Hi,

We currently have two subnets on our network as we are in the process of moving to Windows Server 2K3.

All our new machines in the AD are set to use the 192.168.0.x range, and all old machines not yet migrated are using the 192.0.3.x range. Currently our mail server sits on the 192.0.3.x range and we are giving all the new machines dual ip addresses.

What we would like to do is change the address of the mail server to the 192.168.0.x range and do some kind of routing so that all machines in the old range can still access the server.

I’m not sure about the best way of doing this, either installing a second NIC or buying a router?

Any help would be appreciated.
