Dual ISP's

[Solo4357]

I have a weird situation.. I have PIX nating my servers. However I got a new MPLS connection with it's own internet. Before the path a computer would take was to the hub router--> Pix --> out. Now I want the traffic inbound from the old internet connection to still work but everything else to go out the new router. Do I set up a secondary ip's on the affected servers? How do I route properly? Any help would be great!

To expand what I'm asking...

I have old isp with static ip's natted to a web server. Web server is on the internal network. The internal network's default gateway to the internet is on the new isp. I want the webserver to go to the new internet UNLESS a request is made through the old isp, then route back out the way it came in. Is that possible?

I will be switching everything over but I can't at the moment... any ideas?

This should be easy enough to do. A couple of questions first. Is your current config actually like this:
internal router -> PIX -> ISP Router

Is your new config going to look like this (assuming your config is as above):

                        >ISP1 Router -> Internet
                       /
internal router -> PIX
                       \
                        >ISP2 Router -> Internet

What model PIX are you running??

So you want all inbound internet traffic (which includes return traffic) to come in on the MPLS circuit/interface, and all outbound traffic to go out the way it was before?

pix 515. Basically all outbound to go out the new internet but some or all the inbound to come in the old one (just for some websites) and still go out the old one.
