From what I understood in the documentation, alias command works when you have external DNS and internal client queries the external DNS for an internal host. I have the opposite. Simplified situation is this(really is much more complex)
DNS on inside interface (so that it is protected). PIX has outside and outside2 interface. Internal web server on inside interface will have a different static for both the outside and outside2 networks. DNS server will also have a different static command for the outside and outside2 networks. Will the pix translate ip address of web server in the dns response if a host on outside interface queries DNS server on inside interface, and by the same token, will it translate IP address of web server in DNS response of a host on outside2 interface queries DNS server on inside interface?
