Assuming your DSL line is getting it's IP through DHCP, you need to do
something like:

   interface Serial0
    ip address negotiated
    ip nat outside

   interface Ethernet0
    ip address 192.168.x.y 255.255.255.0 (your LAN address)
    ip nat inside

   ip nat inside source 10 interface Serial0 overload
   access-list 10 permit any

If instead you have a fixed DSL interface, you can use a static IP
definition; the "negotiated" part allows you to pick up DHCP info.
Also, I haven't done DSL on a 3600 so it may not be "Serial0" but some
other name.  "sho ip int brief" will tell you the names.
