Hi,

I have a website(abc.compnay.com) hosted in a local lan the ip being 192.168.x.x and all my users are able to reach the website by internal dns. The same website is nated externally and dns published in the public dns for external users.

In case there is a disconnect to the website fromt the lan side but wan works fine (website works on the public ip but not lan ip) then how do i redirect my internal users to use the public ip rathen than local in the DNS. 

DNS is hosted in Windows 2008r2 box.

Hi,

Add a public dns server as second choice on your clients. Either your ISP's DNS, or Google (8.8.8.8).

So, when users try to access www.yourwebsite.com and your local dns cannot be accesed, the query will go to the next one. Which is the public DNS, and that should be able to resolve www.yourwebsite.com. Have in mind that only www (browsing) will work. If you use Active Directory, your client wont be able to locate any services, if no local DNS is available.
