Static Route Help

I am in the process of installing a new network. New T1, new sonicwall
pro 3060 firewall, the works. The WAN port on the sonicwall is a
static public ip address. I have the lan on a private network. What I
need to do is get a public ip address to function within the private
network. Not using the DMZ. I am wondering if this is even possible. I
am very clueless to static routes. Any help would be appreciated.
