I am configuring a Cisco Router and would like to do NAT so there is a one to one translation from the inside private network to outside public network.
For this example lets assume that 10.10.10.0/24 is a block of public IP's and 192.168.1.0/24 is my private. I'd like the addresses to translate as:
192.168.1.1 -> 10.10.10.1
192.168.1.2 -> 10.10.10.2
...
...
192.168.1.25 -> 10.10.10.25
...
192.168.1.99 -> 10.10.10.99
...etc
Is there a way to do this on 3825 router? It's easy to do on ASA or PIX but reading through the Cisco documents it looks like the routers randomly assign an IP from a pool. I need the last octet of the IP to match on the translation so I can track down which user got which public IP.
