You need to configure 'nat inside' on E0 and 'nat outside' on your dialer
interface. Then configure a ip nat statement, in it's most basic for it
will be something like this:

interface Ethernet0
ip nat inside
!
interface Dialer0
ip nat outside
!
ip nat inside source list 100 interface Dialer0 overload
!
access-list 100 permit ip any any

Martin
