Hello,
I have a simple question. Is it possible with cisco router to forward port range to an internal nat host. I have to forward like 100 RTP ports & i m stucked. If yes please provide the cisco documention like so that i can figure it out. If not is there any alternatives without buying any expensive hardwares ?

Hello, i think it is possible to forward a range. You can do it like this maybe:
E.g.
ip nat pool p2p 192.168.1.10 192.168.1.10 netmask 255.255.255.0 type rotary
ip nat inside destination list 100 pool p2p
access-list 100 permit udp any any range 2000 5000
You specify the range within the ACL itself perhaps? There are examples out there, just google it. I haven't been able to find Cisco documentation on it yet.
Hope this helps.

Tried that way. It won't work. Used the route-map method too. Any more ideas ? Have you tried it yourself ?

Hello
I am not quite sure of this request but it sounds like cisco pam could be of use, Please review the link below it may be of help.
Pam can port map on system/host specific or user defined ports
