NAT on Cisco 1720

Well, I'll like to have my cake in plate :) Can I have the commands that I can run!

Do you already have NAT functioning for outside access, such as for browsing etc from the private network?  If that is already set up and you just need to create the static NAT rules for inbound access, it would be something like:

ip nat inside source static tcp 192.168.0.231 80 209.1.1.1 80

where 209.1.1.1 is the public IP.  This would map port 80 to port 80 on the inside, but you could easily change the port numbers on the inside if you wanted to.

If you do not already have translation of any kind working, you will need to set up dynamic NAT:

ip nat pool funky 209.1.1.1 209.1.1.1 netmask 255.255.255.248 overload
ip nat inside source list 1 pool funky
access-list 1 permit 192.168.0.0 0.0.0.255

interface e0
ip nat inside

interface s0
ip nat outside

This example will PAT the external address 209.1.1.1 and allow all hosts on the 192.168.0.0 range to use the PAT address.  I had to guess on the network masks as I do not know the size of the networks your interfaces belong to.
