Cisco 1700 Dual WAN Config

I've got a Cisco 1720 router and 2 WIC 1-ENET's and IOS v 12.3 (not sure of the sub version, don't have the router in front of me) that I would like to setup as a dual WAN router. First I need to know if the

1720 will even do what I want with the IOS I have or if I need a new IOS or different router. Second I need some help with my config if I can do it. Below is what I'm trying to accomplish.

FastEthernet0 - Internal Network ip 192.168.30.1 providing DHCP to internal network

Ethernet0 - WAN ip DHCP (Connected to Cable Modem) Get next hop through DHCP Route all traffic through this interface except what's defined for Ethernet1

Ethernet1 ip 66.224.2.13 Next hop 66.224.2.1 Route all traffic destined for 66.224.2.0 Network through this interface

Here's my current config: I may be way off on this as this my first attempt at cisco routers.
