Cisco router in between Pix and Switch - routing needed?

I Have a Cisco 2621 router that I am going to place in between my Switch and my PIX-501 to collect and export netflow. I really just want it to collect the Netflow and pass on the traffic to the pix. What commands would I need to use to do this (if any)
here is the format of the connection Legend (inside ip-[hardware]-outside ip)
Desired Setup

I already have the config of the 2621 setup this way and I'm going to test it tonight after hours but I wanted to find out before if I need any other routes to make the passthrough happen.

Also does there need to be any other changes to the PIX other than changing the inside IP? It is the gateway for the LAN. So with the desired setup the Gateway would be changed to the 2621 and traffic would be passed to the pix I guess.

The 3560 needs a default route via (the 2621) and the 2621 needs a default route via (PIX).  The PIX needs a route to via (2621) and the 3560 a route to via (2621).  That should do it these are your only subnets.

Does the "ip route" work on the pix-501?
Drop the "ip route" portion.  It's just:

route inside
