We have Windows Server 2003 with 2 NIC. Both NICs are in different subnet.

NIC 1 - 192.168.15.X All domain clients are in this range (getting IP from DHCP)

NIC 2 - 10.0.0.X This is in router IP address range. Two machines which are not under domain are in these range only


Router default gateway - 10.0.0.1. Router has NAT enabled with one public IP address. From which we are accessing Internet

My question is how could server NIC 1 contact NIC 2?

To contact NIC 2 from NIC 1 and vice versa...

To do this which is the best solution,
1. enabling LAN NATing using RRAS
OR
2. Add route for both these IP range.

Very urgent requirement. Please help me out.
