    You're on the right track. PAT port redirection is the only way I know of to get what you're asking for from a PIX. The syntax for the rules above would look like this:

    static (inside,outside) tcp https https netmask 0 0
    static (inside,outside) tcp smtp smtp netmask 0 0

    Because you are doing this from the outside in, you will need complimentary access-list commands to allow the traffic. You will also want to be sure that the outside addresses aren't also used in a global pool, another static that doesn't use specific ports, or the address of the outside interface. (You can use the outside interface address, just replace '' with 'interface' in the static rule(s).)
