I have a Firewall, with 3 interfaces, One inside and 2 outside. I need to hide the 2rd outside Network from the Inside Network, and need to know how to write the NAT for this.
for a better explaination. The Inside interface is 10.152.0.1/16, Outside interface 1 is 204.139.69.14 and Outside interface 2 is 192.168.0.1.
My network already uses the 192.168.0.0 network, So I need to know how to hide this network from my inside network.
thanks

You can create static 1:1 network NAT for the whole 192.168.0.0/24 outside2 network.
You would need to NAT the whole network to a different unique network so it does not overlap with your inside 192.168.0.0/24 network.
Assuming that we are going to NAT it to 192.168.50.0/24 network:
static (outside2,inside) 192.168.50.0 192.168.0.0 netmask 255.255.255.0
From your internal network, you would need to access the corresponding ip address, for example:
If you need to access 192.168.0.10 (outside2) from the inside, you would need to connect to 192.168.50.10.
Hope that makes sense.
