Possible to have two virtual IP addresses on a CSS?

I've searched the forum but can't find a specific answer, so I'll ask outright.

Can a CSS advertise two different Virtual IP addresses?

We need this as we have two physical locations for our website, but if one site dies all traffic will be directed to the other one. We are using PIX as the front-end firewall, but it cannot NAT two external addresses to one internal address.

The solution is to have two Virtual IP addresses on the CSS, so the PIX doesn't need to NAT.

We are still in design stage, so don't have kit to play with, so thanks for all your help!

Re: Possible to have two virtual IP addresses on a CSS?

Yes - There are several ways of doing it, but the one that cisco intended for such situation, would be using a VIP range (if the addresses are consecutive).

Ex : vip address 192.168.1.1 range 2

If the addresses are not x and x+1 (or x and x-1) you would have to create a content rule that holds the second vip, and is defined in the same way as the primary vip (same services etc etc) - Makes you wonder why there is no "vip address x.x.x.x secondary"
