Intro: I am running a Windows 2003 server with Dual NICs, the RAID controller recently gave up the ghost and a new motherboard and NICs have been put into the server. I somehow had this server working with the assigned IP addresses (I configured this a few years back), but I can no longer make it work. I can't remember what my gateway or DNS settings were, but I'll list what I have them set as now.
Physical Network Layout: Modem -> Router -> Server WAN NIC -> Server LAN NIC -> Network
Issue: Internal network has no internet connection.
The server connects to the internet fine, DHCP is working (configured on the server) and the network can connect to everything internally. I just deleted the DNS records and attempted to reconfigure, but I can't remember how I set this up originally. The only host record is the 192.168.0.1 IP address, and it is set to forward to the ISPs name servers. I ran the auto internet connection wizard in Server Management and set the DNS servers to the ISP's naming servers. I also have the ISPs name servers set in the router. If I ping the .3.1 address from within the network, I get a reply - destination host unreachable.
Desired Result: I'd like the internal network to have internet, and the LAN nic on the server to stay configured to the 192.168.0.1 IP address. I don't care what the IP address of the WAN nic and the gateway are, so long as it works. I did have it working before with these IP addresses - but again - I don't know what I set where to make it work.
Thanks for any assistance provided! :)
