I'm sure this is fairly simple for most but how would I set up NAT for a router with two connections? Config is:

version 12.3
ip subnet-zero
!
interface FastEthernet0/0
 description LAN / Firewall Connection
 ip address 192.168.1.1 255.255.255.0
!
interface Serial0/0
 description to ISP Circuit T1
 ip address 1.1.1.2 255.255.255.252
 service-module t1 timeslots 1-24
!
interface FastEthernet0/1
 description Connection to Cable Provider
 ip address dhcp
!
ip classless
ip route 0.0.0.0 0.0.0.0 Serial0/0
ip route 0.0.0.0 0.0.0.0 FastEthernet0/1 10
!
end

Not sure if I need the nat on the FE0/0 or if it's a global statement.
