NATing Port Range - IOS

Hi,

I'm trying to nat a port range in IOS (12.4) router.

What I like to do is:

anyone form the internet Y.Y.Y.Y hitting my IP address of my outside router
interface Z.Z.Z.Z on ports 10,000 to 20,000 -> forward them to a internal host
(keep the ports) X.X.X.X.

I'm have success when I configure each ONE port per each line - but when ever
I do port range using either pools, ACLs, route-maps with my NAT I'm not able
to get this to work. Again - it works when I do example: port 10,001 to 10,001
but when I do range from 10,000 to 20000 - no luck.

Anyone ever tried this? Is this even supported in IOS? One would think this is
a simple thing to do - but I've been having issues for some time now trying to
figure this out.

Thank you for help.
