    I would disable one of your NICs and only use one to connect to the switch.

    You need to use the built-in DNS server on the DC for name resolution, so configure it and use Forwarders  (Forwarder Tab) for name resolution on the internet.  Also make sure your clients are using it for DNS or you will have real trouble with your Clients logging onto the Domain.

    You can configure your router with any address as long as it is in the same subnet, and is not in the DHCP configured Scope on your server.  But I prefer either using the first or last IP addresss, so your Router and (Default Gateway on all clients/server) address would be  This should be either statically set on the systems, or can be pushed out by your DHCP server.

    Your DNS server on your DC will be the same address as the static IP address of your server.  (

    Subnet is all class C, and Classful, so your configs are correct there.

    Actually, this is a pretty simple setup.  Just make sure that your server has the IP address hard coded (static) and your DNS is working properly.
