Outside Interface IP address

ewong0088 — Mon, 11 Mar 2019 13:56:07 GMT

I woder if using ASA or PIX, can I set up the outside interface with 1 IP then for outgoing (on the same outside interface) with another IP address. For example: outside IP 1.2.3.4 then somehow for outgoing(return traffic if you will) the IP address to be visible is 1.2.4.5 (partner requirement, don't ask 🙂 ).

Doing this on Linux iptable already and now is thinking to change it out to something else,i.e. ASA or PIX.

Thank you for your hep.

use :

nat (inside) 1 0 0

global (outside) 1 1.2.4.5

All outbound traffic will be translated to 1.2.4.5

If you use ;

global (outside) 1 interface

Interface ip will be used for xlation purpose.

Do rate helpful posts.
