Cisco 1720 NATing Issue

[popotech]

Hello,
As soon as you figure someting out your boss drops another pile of s#$% on your desk. Here is what i am looking for, i need to setup NATing on my cisco 1720 router. Right now it is being used for our CDPD, cellular digital packeted data, connection. Here is what we need it to do, our CDPD line is used to connect our 50 odd laptops out on the road to our building. Our network internally is comprised of about 100 pc all 10.1.1.X ip schemes, running roaming profiles with Linux Red Hat/Samba 2.2. What we want to do is join the laptops to our internal linux server domain via the cdpd connection to enable anti-virus updates and windows updates. Now here is the problem we are having, a certain phone company that handles our CDPD line tried to setup nating on the cisco 1720 but to no avail was not successful. The other catcher is that the nating has to be setup for a laptop to make a request and basically come into the network receive the info it needs and the router has to know how to send it back and re-nat it back to the orignal ip addres it came from. ex.

//////////////////////////////////////////////////////////

a.) 166.150.139.X makes requests
------------------------------------->
b.)routers recieves request and nats 166.150.139.X to 10.1.1.2XX --
------------------------------------->
c.) router then allows it into the network with the 10.1.1.X address --
------------------------------------->
d.) hits the router on the way back out --
------------------------------------->
e.) router nat's 10.1.1.2XX to 166.150.139.X --
------------------------------------->
f.) laptop recieves ifo

///////////////////////////////////////////////////////////

So that is why i came here, never been let down once. Here is the ip schemems for the laptops as well as the router config file.

Outside:
Laptops 166.150.139.X (all laptops have static ip)

Inside:
PC's 10.1.1.X (all static ip, No DHCP)

Here's the config file:

Any help offered on this situation is greatly appreciated.

Still doing some research but found out that overlapping is the way we'll need to setup NATing on the router.
