Nat translation

How do I set my pix 525 nat translation to hide internal IP addresses to the maximum extent possible. I need to configure the NAT firewall so that outbound traffic appears as if the traffic had originated at the firewall.

Hi,

You need omething like :

nat (inside) 1 0 0

global (outside) 1 interface

HTH,

Please rate if it helps,

What is HTH

Should the global outside point to the router?

Not sure what you're asking there, but the above commands mean that everyone one the inside will be translated to the outside address of the pix.

Hi,

HTH is Hope That Helps. :-)

If the interface names are the 'inside' and 'outside' then you just go ahead and paste the commands sent to you earlier. Global outside is not a route command so it does not point to any other device. This means the traffic that needs to get NATed/PATed will be NATed/PATed to the outside interface of the PIX.

Hope That Helps,

Please rate if it helps,

Regards,

Kamal
