I have a win2003 server that im using for a gateway, it has two nics in it and im having problems getting it to work properly.
I have the cisco router plugged into an 8 port switch which is where i have the web,vpn & gateway/dns plugged into.  Then on the other side of the Gateway i have that nic plugged into a switch which branches out to office.  How do i setup the two nics in the gateway to work properly. Also atm i am using the cisco router as a dhcp can i still use it as dhcp or do i need to move the service to the gateway server? My network information is

I would disable DHCP on the Cisco Router.  Configure your Nic which connects to the Cisco router with a address of



Configure you LAN nic on your Server to the folowing

IPAddress (or whatever you have your LAN Set to)
Gateway    <BLANK>

Client Address should be given out by DHCP on the Gateway Server.  Addresses should be

IPADDRESS -  (or whatever range you want)
DNS             192.168..0.1

Now Go to RRAS and Configure this as sharing the internet.  Choose your as the Internet Card.  Everything should work.

Ensure you setup your DNS Forwarders to point to your ISP
