Hi. I have setup this NAT all ok. I do have a concern around security however. I know essentially that all NAT will do is hide the internal IP and doesn't provide sufficient security against targeted attacks over port 80. Essentially port 80 is open to the outside world to an internal IP which is not great from a security point of view.
I am aware there are better ways to do this - DMZ etc - My question is how common is it that this type of NAT would be setup. Have engineers seen this configuration frequently?
