We recently assisted a client with the relocation of their website. The site moved from inside the domain to a hosted site; the website still has the same name as the local domain.
Updated global DNS settings and the world can navigate to the website. Updated the local DNS A record by simply inserting the global IP where there used to be a private IP. One can ping the website via URL or IP successfully from inside the LAN. Performing an http connection test is successful, too. However, no one inside the local LAN can navigate to the website. Depending on which browser one chooses to use, the message is basically that the page cannot be found. Chrome cannot find the website, for example.
I'm open for suggestions; thanks ahead to anyone who has a moment to respond.
