Simon, this sets up dynamic NAT translation using the "interface"
specified.
Say you have a router with private address on inside (ethernet) and a
public address on the serial connecting to your ISP, serial 0/0.1
(64.90.8.33) for example.
ip nat inside source list 1interface serial 0/0.1overload
This translates the inside folks who past list 1 to NAT out using the
address of s0/0.1(64.90.8.33) using PAT. We do this on most of our customer
running 1720's.
