Cisco 871 NAT config assistance needed!!!

I am configuring my 871 appliance with IOS 12.3 with DHCP and NAT. DHCP config seems to work cause it supplies ip addresses to workstation I connect to it. With a ip address assigned work station cannot connect to the internet. I think that may be a issue with my NAT configuration. wondering is some of you guru's can give me some insight on what im doing wrong. My running config is below.

fyi... int f4 is connect to another nat'd non-cisco router that works
