I have a linux box using apache that was working normally.

I had to install a sonic wall firewall using NAT

I configured the firewall for one to one NAT

I also have to two windows boxes behind the firewall

The one to one NAT works on the windows boxes without any issues

I changed the IP address of the Linux box from an external IP to an Internal IP

I can ping the linux box from inside the firewall. The FW, and the two Windows boxes can see the Linux box, and I can do anything with the linux box from inside the firewall.

However, the NAT'd packets seem to be droped by the linux box.

I can not ping or address the linux web server or do anything from out side the fire wall.

I have tried to switch the IP's around - I used the ip's on the windows boxes that work and tried them on the linux box. no go.

I think that the Linux box is dropping the packets because they are NAT'd.

Add'l Notes:

The Linux box was set up with a firewall - which I disabled.
I am using webmin interface
I am using apache server

NAT hides the net behind your NAT box from the outside
you need to forward the needed port(s) through your sonicwall
