RRAS

I have a server 2003 PC with 2 NICs installed .I also have a linksys wireless router with dhcp disabled ……so I have static addresses to my wireless clients…..this router is connected to my modem . I’m trying to provide internet access to clients in my internal network and to my server…..so my question is , how do I configure these NICS and RRAS seeing as the address on my external nic is a static address.My server is configured to provide DHCP, DNS to my internal clients. I can communicate with those clients but I cannot get the server or the clients to gain access to the internet.I should also mention that this is also being done on Virtual pc 2007
