PIX515E: NAT one external IP to two internal machines

[rbauerschmidt]

Can you NAT External IP to two different Private IP's? Using a Pix515e version 6.3(4)

For example I want to direct smtp traffic on public ip address 1.1.1.1 to a spam filter(10.1.1.2) but still want the mail server(10.1.1.99) to send mail outbound as that same public ip address.

use static command

u can consider the below sample config

static (inside,internet) tcp 1.1.1.1 465 10.1.1.2 465 netmask 255.25.255.255

static (inside,internet) tcp 1.1.1.1 995 10.1.1.2 995 netmask 255.25.255.255

static (inside,internet) tcp 1.1.1.1 smtp 10.1.1.99 smtp netmask 255255.255.255

change the port according to ur spam filer uses & be sure that the public address is not included in your global list if any

Hope this wiil work & rate if it
