I want to map HTTP (80) and 5080 port of router (192.131.185.207) to 80 and 5080 ports 192.168.0.96 this lines:

...
ip nat inside source static tcp 192.168.0.96 80 interface Dialer1 80
ip nat inside source static tcp 192.168.0.96 5080 interface Dialer1 5080
...

but it doesn't work. Can you help me?
