Need to know the difference between, Source NAT and Destination NAT... My understanding is the Source NAT is No-NAT and destination NAT is the actual NAT.
Also, there are two type of natting, one method is to map a group of IP addresses coming on ingress interface to another group of IP addresses on egress interface. Other method is to NAT the ingress interface to egress interface. Which is one suitable for what scenario? what if there are 2 egress interfaces part of the same security zone?
