Multi Nat

[fortuneplus]

I've just upgraded from a Vigor 2660 router to a cisco 1721 and am trying to replicate my configuration, so please bear with me if my terminology is incorrect.

I have a ADSL Wic installed and have a static IP address from my ISP as well as a block of 6 additional IP addresses.

I've configured the router to connect and have entered some port mappings which work on the static IP address.

What I need to do is to configure the additional IP addresses so that I can do the following

External Address 1 Port 80 -> Nat -> Internal IP Address 1 Port 80

External Address 2 Port 80 -> Nat -> Internal IP Adress 2 Port 80

Can any one help with info or point me in the correct direction with the documentation

Unfortunatly my level of access will not let me look at the link. Sometimes I get the feeling that cisco don't want you to learn!

Is there a public link to this info?

Ok I've got the port mapping working but I must have done someting wrong as a traceroute seems to bounce between my ADSL static address and my router's next hop.

I've set a default gateway to route everyting back out through the ATM 0 IP address by using

ip route 0.0.0.0 0.0.0.0 Dialer1

but do I need to overtly set a route out for my "extra" IP addresses which are not in the nat pool
