Can anyone give an example of how to setup a Cisco 1605R to a DSL line through Cisco's IOS? I need NAT and port forwarding (e.g. web server). The configuration I have does not let anyone on the internet:

interface Ethernet0
ip address (my LAN ip and subnet)
no ip directed-broadcast
ip nat inside
shutdown
!
interface Ethernet1
ip address (my external address and subnet)
no ip directed-broadcast
ip nat outside
shutdown
!
ip default-gateway (my isp gateway)
ip nat inside source list 1 interface Ethernet1 overload
ip nat inside source static tcp (Lan IP) 80 (external ip) extendable
ip nat outside source list 100 interface Ethernet0
ip classless
ip route 0.0.0.0 0.0.0.0 (gateway address)
access-list 1 permit any
access-list 100 permit tcp any host (external ip) eq www
!
line con 0
transport input none
line vty 0 4
login
!
end

What is wrong with this?
