Below is my router that's performing NAT. What i am simply trying to do is perform NAT based on the destination address. Any connection coming from inside targeting 172.16.1.1 and 172.17.1.1 routed on the outside subinterfaces, i would like to NAT overload using outside subinterfaces.

for example connection from inside (any) to 172.16.1.1, NAT using Ethernet0/0.60 address (192.168.60.1)

All seems to work fine. But just wanted to find out if this is the best way to perform destination NAT?

interface Ethernet0/0.60
