Nat and Static internal IPs

I am attempting my initial setup of NAT, and nothing is going well. I have a dual NIC setup in the server, and have assigned all computers static IPs (for various reasons outside this scope). That is just about where everything dies. I have set up client gateways to point to Private interface on the server. The gateway on the Private Interface to the server points to the public interface. Everything inside the network works great, but I can’t get an outside connection from the client. PLEASE HELP!!
