just setup your E0/0 port for the Internet side. If you can't use the 'ip address dhcp' command, you'll need to upgrade your ios
interface eth 0/0
 ip address dhcp
 ip nat outside
 no shut
interface eth 0/1
 ip address
 ip nat inside
ip nat inside source list 1 interface ethernet0/0 overload
access-list 1 permit

If you need to clone the MAC address from your first installation, you can use another interface command on e0/0 to set the mac address to whatever you need it to be.

Get it working, then you'll want to lock it down with some basic good security.
