Ok here is the scenerio. I have a public IP address of x.x.x.x that is nat'd to 10.1.1.1. Traffic is sent from the ISP to 10.255.255.2 which is the WAN side of my Sonicwall. The Sonicwall then sends traffic of 10.1.1.0 to IP 172.31.0.2 which is the Outside Interface of my ASA. Traffic is then supposed to go to 10.1.1.1 which is a server on my DMZ interface of the ASA. Problem, I can see traffic coming in the ASA and being sent out to the 172.31.0.0 Interface, but it never gets to my server. As a test, I can put a laptop on the 172.31.0.0 network and use 172.31.0.2 as its gateway and I can get to the webserver. I'm thinking it has something to do with NAT on the ASA but not for sure. I have suppplied a simple diagram for what I have.
