How to do unidirectional NAT on ASA 8.25 version or Pre 8.3?

Trying to do unidirectional NAT on certain server from outside, different unidirectional NAT when server goes outbound. I found for 8.3 and later. I will appreciate if you have any information on this.

Hi Mohan,

Hi Mohan,

I think you are referring to twice NAT on the ASA:

Hi Aditya

Hi Aditya

No I am referring to unidirectional source NAT. 

1) 10.10.10.1 (client) -> 192.168.1.1 (server)

10.10.10.1 NAT to 172.16.1.1 Outside Zone to Inside Zone

2) 192,168.1.1 (server )-> any destination 

192.168.1.1 NAT to 172.16.5.1 Inside Zone to Outside Zone 

*IPs are just for examples.
