I currently have an issue with my Barracuda NG firewall in Azure. I have some web apps in Azure and the way Microsoft has Azure web sites set up is you can only get to them VIA the DNS name. Microsoft does some type of PAT/NAT translation. If you try and just hit the IP address you will get a 404 error. but if you use the DNS name Microsoft will redirect you to the web server where they are hosting it.
what I am trying to do:
I want to have a DNS name that we setup on our server/domain that points to the outside IP of our Barracuda NG firewall in Azure. I want to set up a rule so it goes from that to the DNS name of the Web app in azure. (I cannot use the IP address of the web site for the reason I stated above).
