Inbound NAT cisco 800 advice please.

I am looking for a router that can provide nat on inbound connections over ISDN. I am considering the CISCO 800 series.
As an example the requirment is to route from a private network to a 192.168.0.0 mask 255.255.255.0 network. Another connection is already setup to route through the firewall to a 192.168.0.0 network. What I need to do on one of these connections is install a router at the remote site with an address of for example 192.168.10.0 and then use static or hide nat to communicate with the devices behind the router. eg a call from local to 192.168.10.10 is routed to 192.168.0.10 at the remote site. Is the cisco 800 series suitable for this?

Thankyou in advance.

Let me understand.....

you are trying to connect two private address spaces over the internet? with NAT? if that is the case it will not work. What you will need some sort of VPN configuration which is available on cisco routers.

NAT only translates internal Address space to an external routable IP. Basically it keeps a table of the NAT'd connectoins in the router so the box on the inside can communicate to the outside world.
