I have Windows Small Business Server 2003 premium edition on my new server box, this hosts a webapp on IIS. It has set up a DNS Server to solve requests to the webapp.

I have a linux server/router that has does DNAT and portforwards port 80 to the new box. My linux router serves as a firewall and dhcp

When i plug the SBS2003 server to the network, it leaves everyone on my network without web browsing, it looks like the DNS requests are going to the new server. I configured the DNS forwarders on SBS2003 to my ISP dns but it doesnt work...

Is there something i am missing?
