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 220.127.116.11 /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
