Hello,
I've a big problem and I hope that someone can help me,
I've the win2003 server, with DHCP,DNS,RIS,RRAS... etc configured and Two NIC cards, one for the Lan and one for the Wan and I've a static IP address from my ISP.

The problem is I've an ADSL line for internet configured on CISCO router 800 series, with the following configurations ( see later - pre-cofigured by the ISP ) , where the static IP address is configured on the ATM0 interface of the router and I've at the same time to give the same IP address on the Win2003 server WAN interface, moreover I don't need to use the dhcp on the router ( I'll stop it on the router ).

In brief my server will do everything, I need to use the Router as a modem.
What shoud be modified on the following router configuration to do that.

Greetings

Your NAT'd IP address is what is assigned by your ISP (?? ). You can't use that same IP for your server while at the same time connect it to your Cisco router. You'll have to use a different IP address for your server. If you disable DHCP then put your server in the same subnet as what's configured on your Ethernet0 interface.

Is there any particular reason you feel that you have to use the same IP on your 2003 server?

Casey
