One-to-One NAT - DMZ to inside - how do I make it work?

L4 Transporter

Folks.

I'm apparently having a particularly stupid day, because I can;t make something as simple as one-to-one NAT work.

Scenario is this.

I have an IP in my DMZ. I have assigned this IP to a particular server which is hosted on my INSIDE (secure) network.

All I want to do is take this IP address and NAT it to the inside address. Something like this

IP addresses have been changed to protect the stupid (me!).

So - request comes in from the web to 1.2.3.91, and I want to redirect it to 10.100.1.120 - only needs web browsing and PING.

but I can not, for the life of me, get it right.

I've got the following NAT rule

Original packet

Source Zone - Outside

Destination Zone - DMZ

Source Address - Any

Destination Address - 1.2.3.91

Translated Packet

Source Translation : None

Destination translation : 10.100.1.120

The security policy is as follows

Source : Outside

Source Address : Any

Destination : Inside

Destination Address : 10.100.1.120

I'm happy for anyone to point out where I'm being stupid and laugh at me - I know it's something obvious, but I'm banging my head trying to sort out what.

thanks

Apply the NAT from Zone --" Outside" to zone" Outside".  NAT lookup happens  PANFW before translate the original packet ( Public IP address).

Did that before I asked the dumb question. As far as I can tell, what I have now configured matches - and the damn thing still isn't working.
