In your topology, you have fa0/1 connected to the cloud... I thought you can only use serial interfaces to a cloud...pls help...

Nice example, but, how would you do this with a dynamic ip address. I have a network consisting of a few 1601's (using VLSM) and I would like to add internet to them. I have a dsl modem that will hand out a public IP but it always changes. All the NAT example that I see use a fixed IP, how would it be different for dynamic? Thanks...
If your 1601's are ... ( 1 year ago by westgatenetworks)
If your 1601's are running IOS 12.1T or above, they should have a command to dynamically assign an IP to an interface. So instead of assigning a static IP on int fa0/1, you just do these commands:
int fa0/1
ip address dhcp
Your Interface will then pick up a dynamic address from your ISP and NAT will run without problems even when the interface address changes. I hope this helps!

The assumption is that there is a DSL or cable modem attached to the int fa0/1 interface.

You shouldn't have to "double NAT" anything, you either let the DSL modem/router do it or the Cisco, one or the other. The best thing to do is turn the DSL router into bridge mode, let it do the PPP negotiation for you and set the Cisco fa0/1 for dynamic. The dynamic or static IP addressing has nothing to do with the performance of the NAT, as your interface needs an ip address before the NAT will work at all.
