Port mapping with a PIX

Can I map multiple public IP's to a single private IP with portmapping?

Lets say I have 2 public IP's:

1.1.1.1
1.1.1.2

I have 1 internal server
2.2.2.1 (smtp and http)

Can I do this:

static (inside,outside) tcp 1.1.1.1 smtp 2.2.2.1 smtp netmask 255.255.255.255 0 0
static (inside,outside) tcp 1.1.1.2 http 2.2.2.1 http netmask 255.255.255.255 0 0

Is it ok to do this? Two public IPs are port mapped to one internal IP, but on different ports. The reason I want the IPs to be different is because we will be adding another box which will be the http server. Then I can point one IP at one box, and one IP at the other.

Im pretty sure this is ok, but want to be sure before I make it live. Thank you.

Sure. no problem.
As long as you don't try to map 2 public IP's to the same port, or 1 public ip/port to 2 different internal systems then you're OK..
One of the benefits of the PIX...

'Tis true...the way you have the static statements is correct...

The order of your parameters in the static statements is correct.  One thing I just noticed, however, is that "http" in the 2nd static needs to be entered as "www" or just "80".
