Setting up Windows Server 2003 – WAN

I am looking for help to set up WAN connection with Windows Server 2003 through ‘RRAS WIZARD’. I have installed two network cards, but the problem is I don’t know how it can be configured. I am using DSL Modem for internet connectivity and there is no router installed. There are four ports in the DSL modem. Server IP is 10 dot 10 dot 10 dot two, MASK is 255 dot 0 dot 0 dot 0, Def. Gateway Ten dot Ten dot Ten dot 1 and DNS is 10 dot 10 dot 10 dot 2. These are the network parameters and there is no internet connection. I want to get internet connectivity on my two client systems which I have added to the domain. If anybody knows the solution to solving this, please help me. I will thankful for all your help.
