We have a server with 2 NIC's (1xLAN NIC & 1xINTERNET NIC)

LAN NIC (192.168.16.100) goes to a switch which connects all the workstations on our network to utilise the servers files and programs (Exchange, File and Print services etc). The Server acts as a DHCP and it issues IP's to all the workstaions with the range 192.168.16.X

INTERNET NIC (192.168.0.1) is connected to our DSL Router which has the IP of 192.168.0.2. The internet is then tunneled to the workstations as listed below:

The Web - Router (192.168.0.2) - INTERNET NIC (192.168.0.1) - LAN NIC (192.168.16.100) - Workstations (192.168.16.X)

Is this setup correct? Whilst the internet does work like this on our workstations, I can't help but thinking that the DSL router and INTERNET NIC should be on the same IP Range of 192.168.16.X
