Hello,
We have this IBM server machine is running an AS400 with HTTP service. Our clients can access the website since it was NATed using Sonicwall.
However, I noticed in the access_log that all incoming logged IP addresses were from our Sonicwall. So I checked the Sonicwall NAT policy and discovered that all source IP address of incoming traffic were being translated to X0 (Sonicwall IP). So I changed it to "Original" so it won't be translated and the server can log the real public IP address of the clients. However, after changing the Sonicwall policy to "Original"... our clients can no longer access the website. I had no choice but to revert it back to the old settings.
Does anyone have any idea why our IBM HTTP server only accepts incoming traffic that have IP address of our Sonicwall? I am not familiar with the IBM HTTP server...
