I am attempting to port forward port 80 from a secondary ISP to a web server. Going from the public address to 10.0.0.2. Considerable research shows my port forwarding statements are correct, but the traffic doesn't make it to the web server.

The path is from the ISP to the pix at 192.168.5.2 into a Cisco 2600 series at 192.168.5.1. The same router alos has a second ether net port on the 192.168.2.x subnet. Out of that router to Cisco 3640 on the 192.168.1.x subnet, to an ASA firewall to the 10.0.0.X subnet.

From the pix, I can ping the 10.0.0.x subnet as well as the 192.168.x.x subnets on the network. I have also tried forwarding port 23 to our AS400 on the 192.168.1.x subnet with the same results.

What do I need to do on either the 3640 or the 2600 series routers to allow the port forwarding to pass?
