Hello All,
I would like to configure this, anyone knows how to get this done?
Requests coming to IP address 10.1.1.1 port range 10000-40000 should be forwarded to 192.168.1.1 20000-20200.
Rgds,
Ceyhun

The feature for forwarding a range of UDP ports is not supported on Cisco devices.
An enhancement request has been filed
for this already.
Details of the enhancement : NAT implementation to support port-range forwarding
Symptom:
Impossibility to forward a range of ports to a single IP address with an easy to use command.
Conditions:
NAT configuration on router running 12.4 requiring port forwarding
Workaround:
Add as many static nat entries needed as the amount of port that should be forwarded. Try the foll if it works:
ip nat inside source static x.x.x.x y.y.y.y route-map NAT reversible
access-list 101 permit udp

Hi,
That answer can't be resolution of the problem. Because it can't make "port address translation" , only accept stated port range. And I think it doesn't be possible with nat config.
Requests coming to IP address 10.1.1.1 port range 10000-40000 should be forwarded to 192.168.1.1 20000-20200.
