I have a transparent firewall (ASA) running 8.4 in a 10.1.0.0/24 subnet and I need to NAT anything entering the inside interface with a 10.x.x.x address to 192.168.1.2.. please can someone tell me the code to do this

Thanks

Hi,

Yes you can nat traffic on transparent firewall from ASA 8.0.2, you would need the following nat statements:

nat (inside) 1 10.0.0.0 255.0.0.0

global (outside) 1 192.168.1.2

Have a look at this guide, for more info:

Hope this helps.

Thanks,

That syntax does not work for 8.4

oooopsss I am sorry

Here's the syntax:

object network internal_subnet

subnet 10.0.0.0 255.0.0.0

nat (inside,outside) dynamic 192.168.1.2

Sorry, I just overlooked it.

Thanks,
