How To Open A Port Range On A Cisco Router

Lets say you want application AAA to have access to UDP ports 5000 to 5020. Your internal address is 192.168.0.1. First create a rotary pool for inside NAT host. Then do a destination NAT with a extended access list:
“ip nat pool AAA 192.168.0.1 192.168.0.1 netmask 255.255.255.0 type rotary
access-list 102 permit udp any any range 5000 5020
ip nat inside destination list 102 pool AAA”
