Restrict access to public NAT port to Network range

Hi,


I am needing to restrict access to a outside NAT translation to a specific IP range and deny the port for all others. 


The current NAT statement is;


ip nat inside source static udp 192.168.10.50 5060 interface Dialer1 5060

ip nat inside source static tcp 192.168.10.50 5060 interface Dialer1 5060


I would like only IP range 125.213.160.0 /22 to be able to access port 5060.


The Dialer 0 interface is used for other port translations and also as the access from internal to external for users.


The router is a 2911 running IOS Version 15.1(4)M1

      

Thanks.
