nat 0 question

[tsrader]

In what type scenarios is NAT 0 used? Confusion as to why / how this is used.

Thanks

This is most commonly used to exempt traffic from nat for use on remote access and lan to lan vpn tunnels. Or any scenario when you want traffic not to be natted. For instance communication between inside and dmz interfaces.

In my scenario too. Only when the inside network access the DMZ network... They access with the original ip address
