I am inexperienced with IIS so I have a few questions about bindings that I am hoping someone can answer
I have an IIS 6 server win one public ip and three websites. I can get to websites from outside the network. But I can not get to them from inside the network. I want to do so without adding any local DNS records or making any changes to hosts file on
anyone's computer. I am not that familiar with IIS host bindings, so I’m not sure if I’m missing something.
Website name , IP address, Port, Host header Value
Default Web Site default 80 (blank)
Website 1 default 80
Website 2 default 80
Website 3 default 80 www.publicname3.com
Reason's why I think the firewall is set up ok:
I'd prefer to create any forward lookup zones in DNS on my domain controller. I know that I could do that to probably work around this problem, but I don't want to be have to manage a whole bunch of DNS records.
Does anyone know if there is anything else I need to do in IIS to get these three web sites to work internally? Am I missing some kind of host header setup some place in IIS?
Thanks a lot for any help,

That is happening because you are using host headers. You can add the internal IP address mapped to the DNS name in your local hosts file and you'll be able to browse the sites on your internal network.

I would like to follow up with what the fix was. The issue was with our Sonicwall firewall. One of the loopback NAT rules was corrupt. The settings appeared correct. We deleted the NAT rule and recreated it with the same settings and the problem is
