PIX 515E - Two ISP's - Trying to create static routes for individual hosts

I just got a second ISP in today which I planned on using to have a couple web servers use, while leaving the rest of my users/servers using my primary ISP as they have been.  

What I was trying to do was create a static route for individual inside hosts... ie -  
192.168.1.10 255.255.255.255  -->  external_gatewayIP_of_2nd_ISP

When i do this, it tries, but renders that host unable to get anywhere on the internet.  I couldn't even access the inside interface (192.168.1.1) from that host (via telnet) after I added that route.  

How can I configure the pix so that I can have 1 or 2 servers nat out through to the 2nd ISP interface?

No can do I'm afraid.  A PIX cannot have 2 gateways out for the simple reason that regardless of which network you are coming from, you still to route a default gateway network of 0.0.0.0 to a destination, and you can only have one default gateway.

If you have 2 ISPs, you *can* use BGP between 2 border routers to load-balance and/or provide redundancy.  A pix though, cannot route default 0.0.0.0 out to any more than 1 destination.

So I need a second Pix to do the job and change the gateway on those few internal hosts to point to the second pix to make this work?
