Our office was just set up with DSL service through a 678 router from Qwest. Along with our router and DSL service, we received 5 static IP addresses. I have set up the 678 as a DHCP server to automatically assign IP addresses to each of the computers on the network. However, the next step is what I am having problems with. I need help in determining how I can configure the NAT on the 678 to map the internal (private) IP addresses to the 5 (public) IP addresses that we received from Qwest. Any and all help would be greatly appreciated.

You have to use dynamic nat.
First you create an IP address pool with the 5 IPs that you have:
ip nat pool
{ netmask
[ type { rotary } ]
and then you create the translation INSIDE -> OUTSIDE
ip nat inside source list
If you still have problems, look at

Thanks for your response. I looked at the documentation for the Cisco 678 but I can't find anything regarding dynamic nat. If I use the syntax that you described, will it work?
Thanks again,
